Erratic Vancouver Hiking Terms
Erratic or Glacier Erratic: is a piece of rock that has been carried by glacial ice, often hundreds of kilometres. Characteristic of their massive size and improbable looking placement. Erratics are frequently seen around Whistler and Garibaldi Provincial Park. Either as bizarre curiosities or a place to relax in the sun. On a sunny day, a large sun-facing erratic will often be warm and sometimes even hot, providing a comfortable and surreal place to rest. The image below is an erratic next to Russet Lake.
This erratic is located beside one of the Adit Lakes near Russet Lake in Garibaldi Provincial Park, Whistler.
The erratic below sits next to the amazing Wedge Hut at Wedgemount Lake. Such bizarrely located erratics are numerous in Whistler and Garibaldi Park.
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).
Glossary of Hiking Terms Vancouver Hiking Trails
Alpine Zone or Alpine Tundra: the area above the treeline, often characterized by stunted, sparse forests of krummholz and pristine, turquoise lakes. The Sproatt alpine is an excellent example of an alpine zone in Whistler. Dozens of alpine lakes, rugged and rocky terrain and hardy krummholz trees everywhere you look. The hostile, cold and windy climate in the alpine zones around Whistler make tree growth difficult. Added to that, the alpine areas are snow covered the majority of the year. Other good places to explore alpine zones in Whistler are Wedgemount Lake, Blackcomb Mountain, Whistler Mountain, Black Tusk and Callaghan Lake.
Arête: a thin ridge of rock formed by two glaciers parallel to each other. Sometimes formed from two cirques meeting. From the French for edge or ridge. Around Whistler and in Garibaldi Provincial Park you will see dozens of excellent examples. Below Russet Lake in Whistler, the glacier at the bottom of the valley, below the lake has a wonderful example of an arête. The far side of Mount Price, near Garibaldi Lake also has an enormous arête. The Wedge-Weart Col beyond Wedgemount Lake is a prominent arête to the summit of Wedge Mountain.
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.
