The winter snowpack was still hiding crevasses. Where it had melted, large swaths of cracked and yawning ice had been exposed, hinting at what may lie beneath the snow cover.
One day earlier, July 8th, Valentina Radic and I had left Vancouver, aiming for the town of Golden, near British Columbia’s eastern border. Our route brought us on a nine hour drive, passing from the Coastal Mountains, through the vast Interior Plateau, and into the Selkirk range near the edge of the Rockies.
Golden was to be the staging point for this summer’s field campaign. The plan was to install a weather and glacier monitoring station on Nordic Glacier. The station was to observe the melt rate of the surface of the glacier, and to record any meteorological varibles that may affect melting (see The Project).
Nordic was selected as its meltwater drains into the Columbia river. This is the largest river in the the Pacific Northwest, and the forth largest in the United States. It stretches for 2,000km, through BC and seven US states, with a drainage basin the size of France. Its waters are used for irrigation and hydroelectric power production, with 14 dams on the main stem, and more on its tributaries. I had encountered the Columbia before, but much further downstream in the state of Washington, while rock climbing (see Vantage Point).
On arriving in Golden, we drove straight to the home of our hosts for the night, Tannis and Steve. When initially planning this trip, we had intended to camp once we got into the mountains, but Tannis and Steve kindly offered us the use of their backcounty ski lodge (Sorcerer Lodge) which is located in the same valley as Nordic. Operating in the area for over twenty years, they have seen firsthand the changes undergone by the glacier. It was inspiring to see the interest and enthusiasm (and knowledge) that they showed for the project, and was a reminder that this research wasn’t just an academic exercise. Joining us in Golden were Brian Menounus and Federico Ponce, two researchers from the University of Northern British Columbia. With our team of four assembled, we stocked up on some soon to be burned calories (with excellent burgers in Golden), and bedded down for an early departure.
Our flight to the glacier the following morning went smoothly, with Steve lending us his experience with helicopter transports. Valentina and I went in on the first run to scan for a suitable site for the station, and to get dropped off on the glacier with the main equipment for the station. Brian and Federico were to travel in on the second run to bring equipment to the lodge.
After several months of looking at Nordic in photographs and maps, seeing it grow larger through the window of the helicopter, I felt excited and nervous. As we drew closer however, I was concerned to see the extent of the snow cover in the area we had been planning to deploy. Working on a ‘dry’ section of a glacier (where there is no snow) has the major advantage of being able to see the location of the crevasses. Not only is this much safer, it allows you to move and work more efficiently, as precautions such as being roped together are not necessary. We had hoped that the winter snow pack would have melted from our site by the time we arrived, but it appeared that, for this season, we were a little early.
We landed on the glacier, and unloaded our equipment with the engines still running. As soon as we were clear of the downwash from the departing helicopter, we roped up and started surveying the area for the flattest spot for our station, probing the snow as we moved to check for crevasses. After the helicopter returned to deposit the larger pieces of equipment, we flew down as far as the lodge to meet with Brian and Federico. With conditions the way they were, we decided we would hike up to the glacier together, and find the safest route to the site.
Each day, our hike to the glacier would begin with crossing the lateral moraine that separated the lodge from the main valley. From there, we would descend and traverse the valley to the other side, crossing the river to do so. The river crossing was a glacier monitoring exercise in itself. As the river’s source is the melt water draining from the glacier, there was a distinct daily pattern in the strength and level of the flow. In the morning, when there had been little melting during the colder night temperatures, the water level would be well below my knee. Returning in the evening, after a day of warm temperatures and sunshine, the flow would be much stronger, pulling at already tired legs. As you’d imagine, the water was pretty cold, and it was incredible to feel how quickly your heat could be drained away.
Installing the station came together relatively quickly. Although the glacier is a very different working environment to the lab or test field, I really felt the benefit of all the trial runs and lab assemblies. The station was constructed, wired, and operating after one, albeit long day, and it was fantastic to have the additional manpower of Brian and Federico, who obliged me with some serious ice drilling. A second day was spent testing to see how the data and power system was performing, and also securing the various components of the station in preparation for two months on the side of a mountain.
Mohammed Ali once said, ‘it isn’t the mountains ahead to climb that wear you out; it’s the pebble in your shoe.’ In this case, it was the mosquito inside your mosquito net. We carried out our field work during the buggiest few days of a particularly buggy season, and these mosquitoes couldn’t believe their luck when they saw us coming. I’ve spent time in the Amazon jungle, and this was comparable. Once on the ice however, the buzzing clouds would disappear, and we could work in peace.
Each evening, with duties on the glacier finished, we would begin our return hike back to the lodge. Despite being tired, this was always my favourite part of the day. No longer focusing on tasks that needed to be done, I could better appreciate the surroundings, particularly in the hour around sunset when everything would be painted gold and blue. To work in such an environment is a privilege, and time needed to be taken to set aside concerns and stresses, and simply take note of where we were.
On the morning of departure, we flew over the glacier to get our last view of the station for the next two months. I will return at the beginning of September to see how well it survived, to dismantle and transport it back to Vancouver, and to start working on what its data can tell us.
We tackled the drive back to Vancouver on the day we flew down, utilising several food/coffee/ice cream stops to keep sleep and the 35°C of the Interior Plateau at bay. Arriving back to the city, I was tired but content that the work had gone well, and looking forward to taking it easy for a few days before preparing for my next trip (Alaska). Calling into the lab to drop off a couple of items before going home, I was greeted by a delivery of 4 large boxes; the starting components for next year’s stations. It was time to get some sleep.
Up Next: I’ve just returned from a glaciology summer school in Alaska; photo-journal coming in the next couple of days.
