Old Man's Beard(Usnea) Vancouver Hiking Terms
Old Man's Beard(Usnea): The lichen seen hanging from tree branches in much of British Columbia. It hangs from tree bark and tree branches looking like greenish-grey hair. A form of lichen, usnea can be found world-wide. There are currently over 85 known species of usnea.
The Old Man's Beard pictured above is along the trail to Panorama Ridge in Garibaldi Provincial Park in Whistler. The image below links to an aerial video of Panorama Ridge. Note the hazy background due to the forest fires in 2014 in Washington State and the Okanagan.
Almost every hiking trail around Whistler will have Old Man's Beard hanging from the trees. Brew Lake, Cheakamus Lake, Whistler Mountain, Blackcomb Mountain and Wedgemount Lake all have sections of the trail filled with these strange looking lichen hanging from the trees. Wedgemount Lake is a stunning hiking destination in Whistler. Click the image below for an aerial video of this amazing place.
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). Wedgemount Lake itself is a magnificent destination for a day hike or spectacular overnight beneath the dazzling mountain peaks and stars.

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 elevation gain makes a tremendous difference when carrying a heavy backpack and unprepared for the exertion. There is hardly a section of the trail that is not steeply uphill. The first 15 minutes takes you into the deep forest and then across Wedgemount Creek. This crashing creek can be heard from quite a distance and gives you a hint of the steepness of the trail to come.

Glossary of Hiking Terms Vancouver Hiking Trails
Ablation Zone: the annual loss of snow and ice from a glacier as a result of melting, evaporation, iceberg calving, and sublimation which exceeds the accumulation of snow and ice. Located below the firn line. Firn originated from Swiss German and means "last year's snow". It has been compacted and recrystallized making it harder and more compact than snow, though less compact than glacial ice. An excellent place to see an ablation zone is Wedgemount Lake in Garibaldi Provincial Park in Whistler. The Wedgemount Glacier has been receding for decades. In the 1970's the glacier terminated with a steep and vertical wall of ice at the shores of Wedgemount Lake. Today the glacier terminates a couple hundred metres above Wedgemount Lake.
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.
Bench: a flat section in steep terrain. Characteristically narrow, flat or gently sloping with steep or vertical slopes on either side. A bench can be formed by various geological processes. Natural erosion of a landscape often results in a bench being formed out of a hard strip of rock edged by softer, sedimentary rock. The softer rock erodes over time, leaving a narrow strip of rock resulting in a bench. Coastal benches form out of continuous wave erosion of a coastline. Cutting away at a coastline can result in vertical cliffs dozens or hundreds of metres high with a distinct bench form. Often a bench takes the form of a long, flat top ridge. Panorama Ridge in Garibaldi Park is an excellent example of a bench. The Musical Bumps trail on Whistler Mountain is another good example of bench formations. Each "bump" along the Musical Bumps trail is effectively a bench.
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.
Bivouac or Bivy: a primitive campsite or simple, flat area where camping is possible. Often used to refer to a very primitive campsite comprised of natural materials found on site such as leaves and branches. Often used interchangeably with the word camp, however, bivouac implies a shorter, quicker and much more basic camp setup. For example, at the Taylor Meadows campground in Garibaldi Park, camping is the appropriately used term to describe sleeping there at night. If instead you plan to sleep on the summit of Black Tusk, bivouacking would be more accurately used. In the warm summer months around Whistler you will find people bivouacking under the stars with just a sleeping bag. The wonderful, wooden tent platforms at Wedgemount Lake are ideal for this.
