Backshore Sea to Sky 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 Squamish Hiking Terms
Ablation Zone: the annual loss of snow and ice from a glacier as a result of melting, evaporation, iceberg calving, and sublimation 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. 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
Backshore: the area of the shoreline acted upon by waves only during severe storms. The West Coast Trail on Vancouver Island Bar: A ridge of sand or gravel in shallow water built by waves and currents. Tsusiat Falls along the 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.
