Backshore                                                                    Victoria Hiking Terms

Backshore: the area of the shoreline acted upon by waves only during severe storms.  The West Coast Trail on Vancouver Island runs for much of its 77 kilometre length along a very distinct backshore route.  Often visible are signs of winter storms that have recently dislodged enormous trees from the rugged coastline.  A backshore can range from as little as a few centimetres high to hundreds of metres high.  The backshore route along the West Coast Trail is often as subtle as a sandy beach edged by a slightly higher border of grass and forest.  Other areas of the trail the backshore is a vertical, solid rock cliff with crashing waves cutting into it far below.  This image(below) is an example of a backshore along the West Coast Trail on Vancouver Island.

The image below shows the result of centuries of backshore erosion at Mystic Beach on the Juan de Fuca Trail in Victoria.

Mystic Falls on the Juan de Fuca Trail.  Backshore erosion continues to cut at the soft, sedimentary layers of the cliff.

Caves created by continuous backshore erosion near Mystic Falls.  With the frequent rainy weather on the coast of Vancouver Island, these backshore caves provide shelter.  Along the West Coast Trail these types of caves are often the preferred locations to spend the night.  The Juan de Fuca Trail is an incredible part of Vancouver Island.  Wild and beautiful, and accessible.  All along the 47km length there are convenient access points.  It's wild, and beautiful, and varied, and deep in the wild rainforest of the coast.  From the beautiful flowers of Victoria to the wild and majestic forest of the Juan de Fuca Trail, the drive just to get to it is beautiful.

There are four main trailheads for the Juan de Fuca trail.  From Victoria China Beach is 70km, Sombrio Beach 95km, Parkinson Creek 100km and Botanical Beach 110km.  The trail can of course be hiked from either end or in parts.  Starting at Botanical Beach and timing the tides correctly allows for a great way to start the trek as you can see the first five or so kilometres at the wonderful beach level.  With the various access points to the Juan de Fuca Trail, you can do several day trips and never walk the same section twice.  All the sections are quite distinct from the rest.  Some trails are wild and overgrown, others are focussed on amazing tidal pools, and still other sections are centred around wide, sweeping beaches.  You can even find good surfing at Sombrio Beach.

Glossary of Hiking Terms                                      Victoria 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.

• Aiguille: a tall, narrow, characteristically distinct spire of rock. From the French word for "needle". Used extensively as part of the names for many peaks in the French Alps.  Around Whistler in the alpine you will find several distinct aiguilles.  Black Tusk in Garibaldi Provincial Park could be called an aiguille, however its long and prominent history has given it another descriptive term of "tusk".  You will find aiguilles on many hikes in British Columbia.

• 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.

• 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.

• Cairns and Inuksuks: a pile of rocks used to indicate a route or a summit.  The word cairn originates from the Scottish Gaelic word carn.  A cairn can be either large and elaborate or as simple as a small pile of rocks.  To be effective a cairn marking a trail has to just be noticeable and obviously man-made.
