I admit, I can be a little nerdy at times. And, in light of my current alma mater, let us conjure Dr. Suess’s imagining of the word [If I Ran the Zoo].

This being said, my Alaska trip became a cornucopia of chance encounters and coincidental run-ins, from people who live in Boston to people I’ve worked with on Polar ice sheets! While I would like to write about all of them, I’ve whittled the “run-in” list to three: Denali National Park, Julia Gourley, and Dr. Carl Benson.

Perhaps its fitting to mention Denali National Park first. It wasn’t until after I was asked to present a poster at the following week’s Week of the Arctic conference that I even thought to visit this majestic park. First established in February 1917 (as Mt. McKinley National Park), Denali NP now sits at 7,329.2 sq. miles, with an additional 2,089.9 sq. miles “buffer” in its preserve. For comparison, New Hampshire (9,279sq. miles) is slightly smaller than the whole of the park and preserve. Denali, or “The High One”, is the Athabaskan name for the mountain that serves as “the roof of the continent”*. My visit was short (day trip aboard a shuttle bus to Eielson Visitor Center), but it was punctuated by numerous animal sightings and my good friend (and shuttle driver), Dawn, that I met while working in Antarctica. I hope to re-visit this marvelous area sometime soon!

The Wednesday poster presentation was actually part of a general invitation to participate in the Institute of the North‘s Week of the Arctic. Although I did not have time to spend all week in Anchorage, I was able to participate in Tuesday’s session (Arctic Council Strategic Planning and Luncheon) where Senior Arctic Official Julia Gourley (State Department) was a speaker and guest. Her role is to help lead US foreign policy development in the Arctic, and it was fascinating to hear her explain the structure of the Arctic Council (high-level diplomatic forum for international cooperation in the Arctic with 8 member states and 6 permanent participants), illuminate some of the key issues currently facing the Arctic, and engage with the conference participants. I only got a chance to chat with her for about 10 minutes, but I invited her to come to Dartmouth and speak with our IGERT folks … let’s hope her schedule allows!

Perhaps the biggest meeting of the trip, in my estimation, was my evening spent with Dr. Carl Benson (and his wife, Ruth). For those keeping score, Carl planned and led a series of traverses (1952-55) that led to his oft-read 1962 CRREL report that, among other things, defined the concept of glacier facies. Indeed, his traverses were the basis for the 2011 Greenland Inland Traverse that Thomas and I undertook last spring. What fun that was! The evening was a mix of tales of derring-do and nostalgia, from train platforms in Evanston, IL, to the great, flat white of the Greenland Ice Sheet. Perhaps most fortunately, Carl delved into some of the glaciological questions that he’s still thinking about … a treasure trove indeed! With luck, I’ll be able to incorporate some of his curiosity into my still-developing thesis! Thanks for a wonderful night, Carl and Ruth!

And thanks, IGERT, for a wonderfully opportunistic Alaskan trip!

[as seen in Dartmouth's The Graduate Forum (newsletter)]

As graduate students, we all share this singular pursuit, this unabashed chase of scholastic glory. We all enjoy the burden of late nights glazed with copious amounts of caffeine and buoyed by an endless sea of scientific papers. We all enjoy the bucolic wonders of Hanover and the Upper Valley, the unrelenting, yet rewarding, joys of being a graduate student at Dartmouth College. If you’re reading this, I imagine you are, like me, toiling away at some novel and intractable question while balancing the rest of your life. Not easy, but we’re all getting by. So what happens when, in the midst of this sometimes-stultifying stupor, you find yourself on the front-end of a 40-day traverse of the Greenland Ice Sheet?

Buy sunscreen!

The 3 amigos ... Thomas, Galen & Giff

That is what I did when I found myself days away from joining the 2011 Greenland Inland Traverse (GrIT). GrIT, conceived primarily as an overland supply-run for the year-round science station at Summit Camp located on top of the ice sheet, recently became open to the idea of supporting science. The first leg of the journey is a flight from Baltimore, Maryland, to Thule Air Base on the northwest coast of Greenland. Thule Air Base is the US Armed Forces’ northernmost installation, located 750 miles north of the Arctic Circle, and serves as the home base and garage for GrIT, a joint operation involving the National Science Foundation (NSF), the US Army Cold Regions Research and Engineering Laboratory (CRREL) and CH2M Hill Polar Services.

Professor Robert Hawley, in the Department of Earth Sciences, originally proposed the idea of pairing science with this traverse. He passed this tremendous field opportunity to two of his current graduate students – Thomas Overly and Gifford Wong (yours truly). Some of the fantastic reasons, science-wise, why this traverse was so tremendous were it provided a comfortable (relatively) platform from which to perform ground truthing studies, it was an opportunity to revisit science sites along a route that was first studied in the 1950s by Carl Benson, a CRREL-based researcher, and it lead to a wealth of data for his lab group to sift through for the next couple years.

But that’s not all. Nearly everyone enjoys fantastic, and sometimes far-flung, field adventures. For me, the thing that made this past field season so special was the traverse itself. It is the journey that is interesting. I’ve been fortunate to participate in polar science before (McMurdo Station [see pg.3], West Antarctica, Summit Station, and Byrd Surface Camp [see "Views of a Deep Field Virgin", pg.11]), but I’ve never had to drive there. I’ve never had to submit myself to 1400 miles worth of ice sheet whimsy. I’ve never had so much of my livelihood rely on what continually seemed like never-long-enough days. And, I’ve never had the fortune to be surrounded by so much serenity. Perhaps my favorite moments, outside of the general tomfoolery that emerges when 6 young-at-heart individuals combine for 40 days of toil and effort, were those spent with my own thoughts as we bounded across the endless ice sheet like a small convoy of ships crossing an endless sea, buoyed by thousands of years worth of snow and ice all waiting to tell their stories.

This story starts out, however, as a pseudo-survival guide for any would-be ice sheet traveler. If you’re contemplating such a trip, I imagine most of the obvious concerns have already been addressed, such as packing a lot of high-calorie food or outfitting yourself with plenty of puffy and warm clothing. Like this summer’s list of things to do in Hanover, I present, in no particular order, my top 5 things to think about when traversing an ice sheet:

1) Be prepared to be cold. Not surprising, but it bears repeating.

2) Be patient. This goes along with the cold component, but hardly anything happens quickly when you’re waddling around in 8 layers of clothing. Seriously.

3) Try not to sweat. This pairs well with that patience thing, for if you do sweat you’ll definitely feel the cold.

4) Eat. You’re essentially stoking your internal, caloric heater with food, so eat often. Besides, when else can you indulge in over 4000 calories a day and lose weight?!

5) If there’s a plane, get on it. As much as I love the ice sheet, there truly is no place like home. I spent an extra 7 days in Greenland because I did not get on a plane. Silly.

And sunscreen? That ranks right up there with oxygen and a -40 sleeping bag!

Hey folks! An amazing (and amazingly long) day culminated in us driving onto base with our traverse vehicles! We’re back! And it was Robin’s birthday, too!

We're home! (almost ...)
[note the the GPS message]

I won’t go into the day too much … I mean, most of it involved either driving or, if you were Galen, GPR’ing. We had started at the “beginning” of the area that has a lot of crevasses, and we wanted to make sure that none had opened up during our traverse. The day involved two fill-ups (for the Pisten Bully), which means a nearly 100-mile day!

Pit stop ... for fuel and strategy.
[the poor weather during our first fuel-stop ... you can't even see Pat at the end!]

Near the “B-zeroes” … an area that was neatly bordered by crevasses on both sides of the track, the weather really deteriorated. Here, we relied quite heavily on our GPS and Galen and his GPR skills (which are finely honed!).

The scene outside our PB that last ~25 miles!
[my view while driving the last ~25 miles ... that boom is only about ~20 feet long!]

Finally … we turned the corner and saw the dark rock of the transition through the swirling white of the storm outside. We parked our cargo and slowly marched into town, lockstep behind “Swing Boss” and his Quad-Trac. We imagined it looked like quite the sight.

So, here I am (we are) … typing on a computer that is resting on a table, something that hasn’t been done since Summit Camp. I’m showered (also last done @ Summit) and filled with fresh fruit and vegetables. I’m sure that Thomas and I will squeeze at least one more post out of this journey … but for now, know that it was an incredible joy to be part of this GrIT group! They (we) made an “out and back” … a first, and certainly not to be their last. Thomas and I did a boat load, er, tractor load of science! We’re happy to report no serious injuries, and we may even give a presentation at the request of the base commander. All in all, it was a wonderful time (one that, with luck, may be repeated in the future) … Cheers!
