Bergschrund or Schrund Sea to Sky Hiking Terms
Bergschrund or abbreviated schrund: a crevasse that forms from the separation of moving glacier ice from the stagnant ice above. Characterized by a deep cut, horizontal, along a steep slope. Often extending extremely deep, over 100 metres down to bedrock. Extremely dangerous as they are filled in winter by avalanches and gradually open in the summer. The Wedge glacier at Wedgemount Lake is a great and relatively safe way to view bergschrund near Whistler. At the far end of Wedgemount Lake the beautiful glacier window can be seen with water flowing down into the lake. From the scree field below the glacier you can see the crumbling bergschrund separate and fall away from the glacier. Up on the glacier you fill find several crevasses. Many are just a few centimetres wide, though several metres deep. Hiking along the left side of the glacier is relatively safe, however the right size of the glacier is extremely dangerous as the bergschrund vary in width and can be measure only in metres instead of centimetres. Hikers venturing up the glacier are advised to keep far to the left or only at the safe, lower edges near the glacier window.
Massive and menacing, the Overlord Glacier enters the valley between Whistler and Blackcomb mountains in Garibaldi Provincial Park. These images are from Russet Lake in Garibaldi Park. Russet Lake is a fantastic alpine lake that lays at the base of the Fissile. The Fissile is the strikingly bronze coloured mountain so visible from Whistler Village. From the Village look into the distance at the Peak to Peak hanging between Whistler and Blackcomb and you will see the Fissile. Its pyramid shape in the distance perfectly separates the two mountains.
Though Russet Lake is not terribly impressive in terms of size or colour, the valley around it is remarkably beautiful. The colours change from moment to moment in and extraordinary way. The distinctive colour of the Fissile and the stark grey of the mountains around contrast amazingly with the blue of the lake and green grass in the valley. So many different factors fill the place with colour. Wedgemount Lake and the amazing Wedgemount Glacier(pictured below) is zigzagged with bergschrund.

Wedgemount Lake is one of the most spectacular hikes in Garibaldi Park. Though it is a relentlessly exhausting, steep hike, it is mercifully short at only 7 kilometres (one way). The elevation gain in that short distance is over 1200 metres which makes it a much steeper hike than most other Whistler hiking trails. Compared with other Whistler hikes, Wedgemount Lake is half the roundtrip distance of either Black Tusk or Panorama Ridge, for example, at 13.5k and 15k respectively (one way).
At a fast hiking pace you can reach Wedgemount Lake from the trailhead in just an hour and a half but at a leisurely or backpack laden pace you will likely take over two hours. The trail is well marked and well used. The steepness of the trail doesn't require any technical skill, however that last kilometre before the lake you will be scrambling on all fours quite a bit.
The sheltered valley, beautiful turquoise lake, wonderfully huge glacier across the valley and brutally jagged mountains all around all contribute to making Wedgemount Lake something special. It's challenging and exhausting to hike to and an absolute paradise to relax in. Down by the lakeside you can actually find two recliner chairs, built out of the rocks by the lake. Such a perfect way to enjoy the sun rising over the not-so-distant glacier across the lake.
Glossary of Hiking Terms Squamish Hiking Trails
Accumulation Zone: the area where snow accumulations exceeds melt, located above the firn line. Snowfall accumulates faster than melting, evaporation and sublimation removes it. Glaciers can be shown simply as having two zones. The accumulation zone and the ablation zone. Separated by the glacier equilibrium line, these two zones comprise the areas of net annual gain and net annual loss of snow/ice. The accumulation zone stretches from the higher elevations and pushes down, eventually reaching the ablation zone near the terminus of the glacier where the net loss of snow/ice exceeds the gain. The Wedgemount Glacier in Garibaldi Provincial Park in Whistler is an ideal place to see an accumulation zone up close. From across Wedgemount Lake you can see the overall picture of both the accumulation zone and ablation zone of a glacier. The Wedgemount Glacier is also relatively easy and safe to examine closely and hike onto. The left side of the glacier is frequented in the summer and fall months by hikers on their way to Wedge Mountain and Mount Weart.
Highpointing: the sport of hiking to as many high points(mountain peaks) as possible in a given area. For example, highpointing the lower 48 states in the United states. This was first achieved in 1936 by A.H. Marshall. In 1966 Vin Hoeman highpointed all 50 states. It is estimated that over 250 people have highpointed all of the US states. Highpointing is similar peakbagging, however peakbagging is the sport of climbing several peaks in a given area above a certain elevation. For example, a highpointer may climb the summit of Wedge Mountain, the highest peak in the Garibaldi Ranges, then move to another mountain range. Whereas a peakbagger may summit Wedge Mountain, then Black Tusk, Panorama Ridge, Mount Garibaldi and many more high summits in the region.
Hoary Marmot: the cute, invariably pudgy, twenty plus pound ground squirrels that have evolved to live quite happily in the hostile alpine areas of much of the world. In the northwest of North America, marmots have a distinct grey in their hair, a hoary colour, so have been named hoary marmots. They manage to survive quite happily in the alpine, largely by hibernating for 8 months of the year and largely for having a surprisingly varied array of food in such an inhospitable environment. They live off of grasses, berries, lichens, mosses, and roots and flowers. And live quite well it seems, as they always look chubby, which has one great drawback. They are sought after by bears and wolves. They have a wonderful defense system though. They are constantly on watch and whistle loudly at the first sign of danger, alerting the colony. The prevalence of these "whistlers" as they came to be locally called, in the early days of London Mountain resulted in it's name being changed to Whistler Mountain in the 60's. Hiking on Whistler, Blackcomb or Wedgemount Lake in the summer will almost guarantee an encounter with a chubby, jolly little whistler marmot.
Krummholz: low-stunted trees found in the alpine. From the German “twisted wood”. Continuous exposure to hostile, alpine weather causes trees to form in bizarre and stunted ways. Many types of trees have formed into bizarre krummholz trees including spruce, mountain pine, balsam fir, subalpine fir, limber pine and lodgepole pine. The lodgepole pine is commonly found in the alpine regions around Whistler.
Nunatuk: a rock projection protruding through permanent ice or snow. Their distinct appearance in an otherwise barren landscape often makes them identifiable landmarks. Nunatuks are usually crumbling masses of angular rock as they are subject to severe freeze/thaw periods. There is a very prominent nunatuk near the glacier window of the Wedge Glacier. The glacier has been retreating in the past few years, so this massive nunatuk marks the terminus of the glacier now.
