Gear Esoterica


No, I don't mean gear a la BPL. Or even paddling or ski gear (collectively known as WHITE water gear).

I mean gear as in bike gears and ratios between front and back for the kind of riding I like.

MC has shown me the amazing La Marg-rie combo and I want to put on a freewheel, one that will match my speed and terrain.

Last summer I experimented with a Middleburn ProTrials bashguard 16t up front and a White Industries DOS ENO freewheel 16/18t in the back. For shifting I used a wee old (1972) Campagnolo Nuovo Record der that is very short cage. What does that give me? It gives me shifting, simplicity, and plenty of clearance on brushy trails and rocky beaches/gravel bars. It gave me the two gear ratios I used the most -- or close to them -- from the old hellbiking days: 1.00 and 0.89

That set up was great on the beaches of the Lost Coast and would go on my bike again for that trip, except that I did want a slightly higher gear too: mostly to keep up with Doom.

Right now, daily I ride the same DOS ENO out back and a Middleburn double up front, 27 by 38. That combo works well for town riding summer and winter (for me). Summer time and when the winter roads are well plowed and icy I use the big chain ring on roads and the little chainring on trails. Winter time I use the 27t front and the 18t rear for soft trails and the 27t and 16t rear for harder ones. It's amazing (to me) what a gear difference of 0.2 does on "slow" surfaces like snow and wilderness trails and "trials".

But now I am planning a wheel-set for something more mountainous. My experience when off-trail (or animal trail/gravel bar riding) in wilderness mountains, is that most of a day is either down a drainage or up a drainage. In other words, I could get by with one DOS freewheel all day.

Heading up a drainage or riding caribou trails of North Slope gravel bars most of the day? Then go with a 17/19 t DOS in the back and 18 t Middleburn up front, giving nice low spin gears of 1.06 and 0.95. Heading downstream all day, where the major variability is going to be sand spinning or cobble plowing vs vegetated smooth pea-vine bars? Then go 16/18 t in back to push 1.00 and 1.13 ratio.

How to carry both? two rear wheels. One run as front one run as back, swapped appropriate to the day's anticipated riding.

Of course my dream rig would be a 20/16t White Industries DOS ENO as that would give two versions of gearing that differs by 0.2.

Yakutat to Glacier Bay: Lost Coast South



Last summer a bunch of us got an email from MC saying he had a packraft and wanted to match it with his fat bike. Wasting no time, I pitched the route I'd bought a 907 for: Yakutat to Glacier Bay, the Lost Coast South, a route Dick Griffith did in the 90s and told me was the "best trip in Alaska."

Well, I have heard that about a lot of routes, and claimed that for a handful of my own, too, so while I considered it, I never attempted it. Mostly because I was unsure of what ocean water packrafting would be like. I hated lake paddling in the old stubby boats (pre-2011), I knew, and so thought that the ocean was just like a freekin huge lake. Nope.

What Hig and Erin pioneered was packrafting biggish crossings. Dick had used an airplane to hop over Lituya Bay and had flown in to the start, down by Icy Point. After the peripatetic couple gushed about it on blog, book and lecture, I wanted to do it even more, going so far as to scheme and join Skurka on his trip, but instead settled for the Wrangells with him in May 2010.

As for what part of the Lost Coast appealed most, going south was better than re-creating the Eric/Dylan bike route north, as the north route (now something of a backcountry bikenraft "trade route: with this pair and this Italian soloist repeating it) looked challenging but not that appealing nor wild. Heck, there are logging roads and lodges and lots of non-wilderness between Yakutat and Cordova, dissuading me from that route.

Plus by going south Eric (gear maven) and Dylan would want to go, too, as their trip sounded punishing and I was sure they'd like to "complete" the Lost Coast.

The southern Lost Coast looked burlier, wilder, prettier, more mountainous -- my kind of route. And if risk-averse Andy could do it solo, then certainly we could do it with bikes.

"World Class bear trails" had been noted by all, too.

With beta from Skurka and Hig providing comments like "A bike?" and "La Perouse? Yea, just walked on by!" and even both of them saying their route over to Brady Glacier/Taylor Bay from the outer coast was "bad", I felt prepared.

Looking at the map and Google Earth, it was clear that the route fell into roughly three pieces that reflected the fraction of pedaling that would be available.

The first piece to just south of Dry Bay and north of the creek to the Grand Plateau Glacier looked like a long beach ride, punctuated with some boat crossings.

The second piece looked like about half pedaling, half pushing/carrying past glaciers and rocky points, ending down a bit south of Icy Point.

The third piece looked like pushing and paddling and Eric and I had different ideas about how to get over to Taylor Bay and MC and I different ideas about how to get to Icy Straight.

Earlier, I posted some stats about the route and Eric posted pics and MC a nearly viral video.

In general, the first half is dry.

For some dumb reason, neither of our first camps had drinking water.

The riding nears boring, but has some super cool driftwood and dune sections, and you'll want more than one gear. I had two and liked them both. The views of St Elias to the north and Fairweather to the south are great as long as the weather is nice. If the weather were bad, I am thinking you'd have headwinds and rain.

Dry Bay would be a great destination, if you wanted a short, less committing trip. Even as an out and back.

We got off the plane, packed our bikes, ate dinner and road to the beach, then pedaled to the Situk and camped. We boated across Situk River in the morning and made it to a couple hours shy of the Alsek. We crossed the Alsek as the tide came in and it was easy. We had coffee on the south bank. My point is the down an back could be, like, a three day trip.




The good beach continues down to the big boulders just before the northern outlet of the Grand Plateau Lake. Bear trails take you to the put-in at the lake where we found a note from Gordy and Thai. A funny note, about how silly we were to be riding bikes. It was on a Lindt chocolate wrapper. It was a delight.

We paddled the entire length of the lake -- first half in the twilight looking for a beach to camp on and finding one that was scary when a mini-tsunami followed a five minute calving event. Doom slept on his boat that night.

The next day we paddled through amazing icebergs to the far end of the lake and then stumbled through bad Class IV brush with devils club, raspberry, nettles, and a giant curious bear that about got Doom pooping his pants when he bumped into it in the thick forest and it huffed at him.

Great beach riding starting on sand, increasing to gravel, then on to cobbles, and finally boulders leads to the spectacular Cape Fairweather. Here we alternated between shoving bikes down bear tubes on the wooded bluffs or stumbling and lifting loaded bikes over big boulders on the "beach".




Beyond we had great riding with remarkably constant beach backed by uniform forest. See Eric's clip here. We pedaled onward at the amazing 6-7 mph (we had a tailwind -- generally we get 4-5 mph and sometimes only 3 mph in soft sand) and camped at pretty Eagle Creek, a few miles north of Lituya Bay.

Thankfully the notorious Lituya was easy and calm but I was nervous in my wee Scout and steep but short swells as we poked out into the bay. Near the far shore a wicked fast current whipped us out toward the mouth and I ferried like I was in a river to get out before going too far. More pushing on stubby bear trails past a fantastic sea lion haul out led to more riding. But again, the pushing was very bad before the good riding, very BAD (not like the photo below).




Unlike the mountain hellbike trips of the nineties, this beach riding offers a less frequent split of riding vs pushing/carrying. Here on the Coast it's like, OK, two hours riding followed by two hours stumble-f*cking. Hellbiking was more like 5 minutes riding, 2 minutes pushing, 3 minutes riding, 7 minutes pushing. I exaggerate, but both seem to be about 50% non-riding to 50% riding but in different scales of time. On the coast it can be an entire day of riding, followed by an entire day of boating, followed by an entire day of pushing. This was new for me.

As we headed south the coast became rockier, not with boulders so much as with bedrock, rideable, challenging bedrock. There were some tough creek crossings, pinned between whitewater and surf, through rounded, polished boulders slick with green algae. Check the video below for some of that nasty action. Watching me with my bike over my head terrified the others. But watching them man-handle their frame-bag loaded bikes -- at one point Parsons just dropped his bike and watched it float nearly out to sea -- convinced me that over the head was far more stable.




We camped in view of La Perouse, an enormous surging glacier that had poked its brown head out into the Pacific, not fully, but enough to block the easy walk that Hig and Skurka had encountered. In fact, just a week earlier Thai and Gordy snuck by scrambling on boulders of ice, but we found the ice calving into surf, even at low tide.

Still, I pushed us into a dangerous situation, below calving ice and calf deep in surf that surged past ice blocks and boulders. When we turned a corner after an open area of easy walking, only to see massive cliffs shoved into surf, it was clearly time to retreat and sort out other options.

At one point on the way back a massive chunk of ice collapsed with in thirty feet of Doom, a terrifying moment that got us all running.

Dylan and I liked the idea of going over the glacier as opposed to Eric's idea of a surf launch. My boat was just too tiny to hop in easily with its fat bike cargo and narrow little slit through a mylar spray deck.

"I won't go first," was my cowardly response, "but I will go third." That way I'd see how likely I was to swim getting out past the breakers.

Following Eric's bold lead, we surf-launched our bikes. It was cool and felt clever, sneaky almost, like we were getting away with something risky as -- a mile or more from shore -- we paddled a few miles of the Pacific Ocean past a huge glacier.

Thankfully it was sunny and calm and warm and Doom took my front wheel and the only carnage was MC surf crashing and swimming at the landing. A six foot wave toppled him. The rest of us surfed in sweetly.

South we rode, sometimes pushed, crossing Little Bastard (my name) and Big Bastard Creeks (by raft -- also my name), two slimy, steep, cold streams draining Finger Glacier.

My favorite riding and where I found my two gears, one brake, and rack allowed me to ride more than the others, despite their massively higher skill level, was the bedrock spires and cobble beaches north of Icy Point. With no weight on my bars and a front brake and lower gear -- gosh it was sweet!





Written on my map these words capture some of the exuberance:
Best riding of the trip! Always challenging, always unexpected. Doom and I out front, swapping leads, grassy trails past rocky spires, weaving and dropping into chutes, all unexpected, unpredictable, unlikely, improbable and rideable! Awesome.
By the time we made our solstice camp past Icy Point our routine of twelve hour days followed by twelve hour camps set next to running fresh water was set. We got wood and set up 'mids and I heated water up in a big one gallon pot, but these are modern days and everyone ate food out of their own private plastic bag filled with water from their own private cook pot. At least we shared the fire and sometimes the tent, although I usually slept outside by the fire where the bugs were not bad. In the morning our group showed some unity when we all had coffee from the gallon pot. Yum.




Always the ballsy boater, Eric had us put in directly to Kaiknau Creek and float its splashy current into Palma Bay where he and Mike promptly paddled as far out to sea as they seemed to dare. Must have been an optical illusion for while I paddled straight for a point, Mike and Eric seemed to paddle further out to sea, presumably paddling for the same point.

Always the adventuring thrill seeker, Doom called up a whale that blew its spout on him in the deep bay. Startling as the bear!

We'd hoped to get out at Astrolabe Point for a break after La Palma, but the little lagoon was slimy with kelp and stinky with a dead harbor seal. Only Eric and Dylan climbed out. I peed and bobbed in my boat and we moved on, finding a cove on Sugarloaf's east side with driftwood, hot coffee, and a beach.

Paddling the calm inlets and bays was a treat and we were often visited by hummingbirds as we made our way toward Graves Bay. Near Libby island, Eric found a leak in his raft's valve (c. 2003 model, I think) and he patched it before shoving off again.

Our camp at Graves Harbor was even more idyllic than the last, made more interesting by a bear visit in the morning.

Eric had planned out a route that linked lakes and ponds, but these were mostly dry, muddy, rocky and brushy and it took us six hours to go three miles. See the map for a better way that requires a quick climb then a long paddle.

The brush was so bad that we blew up for a pond less than 100 yards long and THAT saved us time. On the far side of that pond we picked up a meadow, leading to a bear trail and another short lake paddle that took us to the newly grown brush beside the Brady Glacier.

Amazingly, isostatic rebound has changed the face of the water bodies marked on the USGS maps made in the 1950s. The islands shown on the eastern side of Taylor Bay are now peninsulas.

We made another dry camp and nobody but stubborn ole' MC wanted to bushwhack even a mile to Dundas Bay. So we democratically dragged our boats across mudflats and paddled Fern Harbor, then paddled out into North Indian Pass and Icy Straight.

These were idyllic waters for our boats, despite all the terrible stories and dire warnings Eric and Mike had heard from non-packrafters. Once again I recalled risk-averse Andy and Hig pointing out that Icy Straight is fast and safe and easy.

Like those saltwater explorers, we, too, made good time, pulling out for water to drink at the west side of Dundas and then paddling whitecaps over to the east side. We waited for the incoming tide (so much quicker!) at another creek opposite Lemesurier Island, hunkered in a short camp till morning, again waiting to ride the incoming tide, then cruising as fast as 5 mph without paddling as we took the tide into Glacier Bay and Gustavus, with whales all around.

An altercation with an uptight, quizzical park cop killed our buzz. Dylan got a $200 ticket for peeing into the water (we split it five ways) and threatened us with our un-permited trip.

Afterwords we pedaled into town feeling triumphant but let down by the Park Service again. What's wrong with them?

Gustavus seemed neat. We had pizza and beer then got on the 5:45 PM flight back to Anchorage, our buzz back and glowing.

"Best Trip In Alaska"?

For us it was during those ten days in June when it never rained and we saw the wildest coastline America has to offer.

All by fatbike and packraft, my favorite tools for exploration.

Magical Mystery Tour: Yakutat to Glacier Bay on fat bikes and packrafts




Over at the the captain's blog is a bit on a trip so rich and so good that I can not write adequately.

I shot essentially no photos, only these "accidents": Be sure to click on them and see them in their big glory. MC has posted some beauties.

But lots of video: 70 gigs of video -- and that's just mine. All with the new HD GH1 and Go-Pro.

I can offer up some stats:
  1. 225 miles total.
  2. 135 miles riding every sort of beach sediment you can imagine.
  3. 65 miles paddling lakes, rivers, streams, ponds, sloughs, oceans, bays, fiords -- we used our boats 25 times.
  4. and 25 miles of mostly stumblef*cking.

The powerhouse Lost Coast Pugsly team of Eric Parsons and Dylan Kentch, with Mike Curiak of fatbike Idita-routes and "Doom" Steve Fassbinder got me through with humor, at least two fires a day, and cowboy coffee every morning.

We saw more eagles than sea gulls. Enough bears to make it interesting, but not so many as to be stimulating. We saw sea lions and whales, suspensefully close.




We saw no one else for days, but got a note from Gordy and Thai deep in the wilderness. They walked the coast to Gustavus and then skied the Fairweather Range back, we heard. No word yet on their trip completion.

For me this was among the top ten trips, ever, and would make for a long challenging Wilderness Classic.

Our camps read like a geography of this wild coast: Situk River, Dry Bay, Grand Plateau Glacier, Cape Fairweather, Lituya Bay, La Perouse Glacier, Icy Point, Graves Harbor, Taylor Bay, Icy Straight.

The bike and boat combo was the only way for us to go. We looked forward to the miles and miles of sand and gravel, even cobble beaches, as they were all rideable. Only when the boulders got to be the size of American sports balls (hardballs, softballs, footballs, basketballs) and cliffs of ice or rock met the surf did we set on pushing and portaging our bikes or paddling our boats.

There are highlights:
  1. Watching Dylan eat his 3 lbs of cookie dough straight out of the gallon ziplock while bobbing in 4 foot swells in his packraft.
  2. Hearing Mike share stories about a mutual friend whose initials are RR and who lives a bit north of Anchorage.
  3. Following Eric's lead into the Pacific breakers off La Perouse Glacier, his Surly Pugsly bravely crashing surf on the bow of his old leaky Alpacka.
  4. Riding with Doom on bedrock and cobbles and sea grass bear trails as far as we could go without dabbing.




We were treated to wonderful weather, spectacular scenery, ever-changing terrain on what is quite likely the wildest coast in the USA.

The riding on either side of Icy Point was pretty much among the best wild riding I can recall, improbable and delightful with the aluminum 907 with its one brake and two gears, a rear rack and a backpack, ideal. Thankfully our food loads were light at that point.

Another watershed moment came with tidewater paddling. I now know how Hig and Erin stuck with it from Seattle north: it's so much better than the alternative. Heading into Glacier Bay we moved at 5 mph. Matching travel to tidal flows was super satisfying.

We averaged 3.3 mph on bike (including rest breaks), 0.6 mph stumblef*cking on the boulders or f*cksticked bear trails, and 2.3 mph on the paddling stretches. That's with the fat bikes on board.

Alpacka made a four pound "Super Scout", six inches longer than the normal Scout. It included a spray deck.

Such a great and perfect boat for me on this trip, although a bit spooky with the 60-70 pound load at the start.


Maybe I'll get some video together to give a taste.

Old School


A sure sign of age is when your favorite techniques are revealed to be "old school".


I have discovered that I am old school.

I like rain pants and hard shells, sharing a tent, meals, and a big cook pot with others.

I wear sleep clothes.

Call me old school, but when skiing on the Harding Icefield, it's hard for me to give up my sled for just a pack, and planning a "bikepacking" trip I find it hard to give up my rear rack.



As visible above my rear rack holds my Sawyer paddle shaft and inside that compression stuff sack (vintage 1996) is 10 days' dinner and breakfast and a gallon cook pot.

That little bit of blue foam will serve as insulation and a packraft seat when paddling. Right there it's keeping the rack from wearing a hole in the bags and makes it easier to get a good tight load, which I need for riding.

On top of the food bag is a Go lite shelter for three.

Notice all the straps. They'll be handy for getting the bike on the boat when bikerafting and for setting up tent (I carry no stakes).



While I may be an old dog, I am still learning some new tricks.

There's that Epic Designed Revelate thingy up front holding an 8 pound Alpacka 2011 model Llama with thigh straps.

I went and rode some bumpy local root wad trails with this and found that the packraft holder thingy bounces around a bit.

I must have put it on wrong, but with another single lash strap, I reefed on that bundle and tamed it so my handling was far more nimble than you'd think of fat ole me on my fat bike with a 30 pound load (that's for ten days) split between pack (10 pounds), rack (15 pounds), and bars (5 pounds -- this raft is not the one I'd use for bikerafting -- it's just a test load).

The pack is my last Cascade Designs Seal Pack (vintage 1997) with a 25 L P.O.E. dry bag holding a Go Lite Quilt, sleep clothes [Patagonia wool base top + bottom, socks], rain gear [pants + anorak], wound kit, lunches, Skurka cat food can, and other stuff I'd need a spread sheet to post properly, I guess.

I like to portage with my head through the main triangle and the rear rack resting on my pack, so I haven't gone to a frame bag just yet. And I do like my rack cause it holds twice the volume of a seat bag.

Not sure I can put 15 pounds in a seat bag, can I?

Anyway, here's an old story I wrote and maybe had published in the UK back in the mid 90s. It's pretty obvious who our sponsors were and it does seem pretty dated.

But with the new stoke on about bikerafting and "bikepacking", some readers might find it pertinent today.

Plus it's a good review for an upcoming bike trip!

Ice-worms, Boofs and Bunny-hops: The Beauty of May in AK



A handfull of us glued in thigh straps last week, huffing glue and MEK while drinking Moose Drool, I think it was, and eating Great Harvest peanut butter chocolate chip mega-cookies at Alaska Raft and Kayak.


Yes, quite a party with Jeff C., Toby S., and Tony P. We had to wait for the glue to dry and so didn't consummate the party the way we should have: with a run down Six Mile's Third Canyon boofing everything in sight with those new, cone-headed, long-tailed, 2011 Alpacka Rafts.

By the time the glue was dry I headed for the Harding Icefield with Amy (my snow algae grad student) and Melissa (my ice-worm student) and Tyler (undergrad assistant). It was an Alaska Pacific University research trip investigating glacier ecology.

The weather was sunny and interesting with some low blowing snow one morning and cooking sun the other. Our main objectives were to drill holes through the snow and into the underlying ice to anchor "ablation cables" for measuring snow melt over the summer using the steam drill:




We had the guys' and gals' tents. The gals' tent looked far more spacious than the guys', and the gals even managed to build a multi-walled wind block from the snow.



Another objective was to install a worm cam to shoot the emergence of ice worms as the season progresses and measure the light and temperatures simultaneously.



Basically we got up at 7 AM, melted snow, ate breakfast and headed out for our drilling project with the steam drill, a pressure cooker-like contraption that forces steam down a hose and so melts a hole in the ice and snow.



The skiing was great.



And the work crew stellar. They called the steam drill, "Hookie".



Tyler Katzmar, Hookie-meister.



We drilled about three dozen holes -- actually they drilled. I was just the supervisor/surveyer.



After we put in the holes, Amy fertilized her experimental plots to see if she can get more snow algae growth by adding nutrients to the snow.



We just worked on a small corner of the enormous icefield. Look closely in lower left to see the skiers.



After two nights on the Icefield we headed out, the gals a few hours ahead of the guys. The icefield was great traveling.





The gals had passed the Harding Icefield emergency shelter a couple hours ahead and would get down so far ahead of the guys that they went into town and got pizza and beer.



Spring had sprung and, boy, was the snow rotten on the trail.




And the bridge slick.




In the three nights we were away, spring had come.



I've written here about the Harding before and even after like my dozenth trip up there I am reminded of how much I like its Pleistocene austerity.

Skiing across its flats lets my mind wander through hypotheses big and small about why and where things live and grow up there, and this was one of the more productive 96 hours I've had there.

It's just that hike up and down with big loads that keeps me from returning every year instead of every other!



But the real reason for this post is to provoke readers with my fatbike's gearing arangement: a trials size dingle:



Look at the drive train! 16 T chainring and 16/18 T freewheel.



These are my two most-often used gears (1:1 and about 0.8:1) when riding wild. Since I only needed to shift two gears (and would need a chain tensioner anyway) I decided to do rear dingle rather than front dingle.

The derailleur is from my old teen-age Campy bike -- very retro.



I tested it today by riding the Brown Bear Trail on Hillside coming and going with ease.

Is it slow? You bet!

If I want fast I'll take my Pivot 429 out and rip, snort and roll. But for stability and crank and slo-mo fun this low geared dingle and 7 psi is just my ticket to ride.

A moment I have been waiting for

Mike Curiak has a packraft.

Curiak is someone whose biking is inextricably linked to water.

I know of him best as a snowbike expeditioneer, having likely made more trips (maybe a dozen?) from Anchorage to Nome on the Iditarod trail than anyone else without a snowmachine or dog team. He's also into riding chunk in the desert SW (water and deserts are linked by definition).

So now he has a packraft, the 2011 model, which is the dream boat come true. The big boat that can do it all: flatwater and whitewater, big loads and no loads.

I smell an epic adventure in the works.

That is, maybe Mike will come up for the other soft substrate fatbiking: big beaches and icy bays.
