Bushwhack - Vancouver Hiking Terms

Bushwhack                                                             Vancouver Hiking Terms

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.

Bushwhacking the Wedgemount Lake Trail

The images here are of the Wedgemount Lake trail in the spring after winter storms have smashed the forest.

Bushwhacking the Wedgemount Trail

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.

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 several 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 a serene and 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.

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.

Glossary of Hiking Terms                                   Vancouver Hiking Trails

Ablation Zone - Vancouver Hiking TermsAblation 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 Accumulation Zone - Vancouver Hiking Termssublimation 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.

Alpine Zone - Vancouver Hiking TermsAlpine 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.

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 Barrier Beach - Vancouver Hiking Termsthe 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 - Vancouver Hiking TermsBench: 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 - Vancouver Hiking TermsBergschrund 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.
