Crevasse Sea to Sky Hiking Terms
Crevasse: is a split or crack in the glacier surface, often with near vertical walls. Crevasses form out of the constant movement of a glacier over irregular terrain. Crevasses are both revered for their dramatic beauty and feared for their inherent danger. Crevasses are often dozens of metres deep and less than a metre wide. The fear of slipping into one of these ever-narrowing chasms is well founded. When learning about safe glacier travel and roping techniques, extracting someone from a crevasse is a huge part of the training. Crevasses are sometimes hidden by recent snow and thus instantly plunging through a a snow bridge is a constant worry during glacier travel.
Across the valley from Panorama Ridge(pictured above), you will see hundreds of crevasses. Panorama Ridge is easily one of the most amazing hikes in Garibaldi Park. The 15 kilometre hike from the trailhead at Rubble Creek to Panorama Ridge takes you through beautiful and deep forests, across countless idyllic streams, through meadows filled with flowers, and past dozens of jaw dropping viewpoints. The amazing views start once you reach Taylor Meadows and get even more spectacular as the trail progresses.
Click the image below for an aerial video of Adit Lakes then a view of Overlord Glacier, then the Fissile, then Russet Lake. showing crevasses. 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.
Below is an aerial video of Wedge Glacier above Wedgemount Lake in Whistler. Crevasses run all over this glacier. 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. Many sleep under the stars on one of the many beautiful tent platforms that dot the landscape. Solidly built, wooden tent platforms are everywhere you look at Wedgemount Lake. Strategically positioned, these platforms manage to maintain an amazingly secluded feel despite their numbers. In all Wedgemount Lake has 20 of these tent areas. Most are wooden, but several down by the lake shore are gravel, yet every bit as nice.
Glossary of Hiking Terms Squamish Hiking Trails
Bar: A ridge of sand or gravel in shallow water built by waves and currents. Tsusiat Falls along the West Coast Trail on Vancouver Island has an excellent example of a bar. An enormous and ever changing sand bar created from the waterfall meeting the Pacific Ocean. Often this bar is a dozen metres high and 400 metres long as it runs parallel to the ocean before flowing into it. Similar to a barrier beach, however a bar is more pliable and recent than a barrier beach, which tends to have long-term plant growth on it.
Barrier Beach or Island: a land form parallel to the shoreline, above the normal high water level. Characteristically linear in shape, a barrier beach extends into a body of water. In Garibaldi Provincial Park at Garibaldi Lake there is an excellent example a barrier beach leading toward the Battleship Islands. The West Coast Trail has an ever-moving barrier beach at the famous Tsusiat Falls camping area. The broad falls cascade off a sheer cliff and cut a constantly changing path to the ocean. The barrier beach can only be reached by a precarious log crossing or by wading across the rushing flow of water. A barrier island can be quite beautiful. An excellent example is Sea Lion Haul Out Rock along the West Coast Trail. This enormous, flat topped, solid rock barrier island sits just a few dozen metres from the trail. Hundreds of sea lions make their home here and provide a constant show for passing hikers.
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.
Bushwhack: a term popularly used in Canada and the United States to refer to hiking off-trail where no trail exists. Literally means 'bush' and 'whack'. To make your own trail through the forest by whacking or cutting your way through. Often used to plot a new trail and trail markers are used to mark various routes until a preferred route is found. In Whistler and Garibaldi Provincial Park, bushwhacking may also refer to an early season trail that is littered with fallen trees from winter storms. Existing trails can also become overgrown and require bushwhacking to navigate through. The Brew Lake trail in Whistler requires some bushwhacking for some of the overgrown trail. A bushwhacker is a term used to describe someone who spends a lot of time in the wilderness.
Buttress: a prominent protrusion of rock on a mountain, often column-shaped, that juts out from a rock or mountain. They are often so distinct as to be named separately from the mountain they protrude from. Buttresses often make a viable bivouacking option on an otherwise steep mountain. Numerous in the mountains surrounding Whistler, the term buttress is frequently heard while hiking, scrambling, ski touring and climbing.
