Cornice - Vancouver Hiking Terms

Cornice                                                                     Vancouver Hiking Terms

Cornice: a wind deposited wave of snow on a ridge, often overhanging a steep slope or cliff.  They are the result of snow building up on the crest of a mountain.  Cornices are extremely dangerous to travel on or below.  A common refrain of climbers is that if you can see the drop-off of a cornice, you are too close to the edge.  Cornices are dangerous for several reasons.  They can collapse from hiking across or they can collapse from above.  A third danger to consider is the fact that they can often trigger a massive avalanche that extends a considerable distance from its starting point.

Cornice in Garibaldi Provincial Park

The cornice shown in the above and below images are of Panorama Ridge in Garibaldi Provincial Park, Whistler.

Cornice in Garibaldi Park

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.

Cornice in Garibaldi Park

Once you arrive at Panorama Ridge and its phenomenal vantage point, high above Garibaldi Park, you will stare in wonder.  Mesmerized first by Garibaldi Lake, far below you and looking unnaturally blue, the lake looks amazing surrounded by green, untouched wilderness and snow capped mountains.

The main trailhead for Panorama Ridge is at Rubble Creek, 25 kilometres south of Whistler Village on the Sea to Sky Highway you will see a Garibaldi Park sign indicating the turnoff.  From the highway a paved road runs for 2 kilometres to the Rubble Creek trailhead and parking area.  This is the most popular and close trailhead for Garibaldi Lake, Taylor Meadows and Black Tusk as well as Panorama Ridge.

Glossary of Hiking Terms                                   Vancouver Hiking Trails

Col - Vancouver Hiking TermsCol: a ridge between two higher peaks, a mountain pass or saddle.  More specifically is the lowest point on a mountain ridge between two peaks.  Sometimes called a saddle or notch.  The Wedge-Weart Col is a popular destination at the summit of the Wedge Glacier in Garibaldi Park.

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.

Cross-ditch: a ditch that carries water from one side of a road to the other, deeper than a waterbar.  Though useful in directing water across roads, natural cross-ditches form on logging roads and can become so deep as to become serious obstacles to vehicles.

Culvert: a device used to channel water under a road or embankment.  Many hiking trails in BC have culverts to direct water under, rather than over hiking trails to prevent erosion.

Diagonal Crevasses: form at an angle to the flow of a glacier.  These are normally found along the edges where a glacier ends.

Hoary Marmot: the cute, invariably pudgy, twenty plus pound ground squirrels that have evolved to live quite happily in the hostile alpine areas of much of the world. In the northwest of North America, marmots have a distinct grey in their hair, a hoary colour, so have been named hoary marmots. They manage to survive Hoary Marmot - Vancouver Hiking Termsquite happily in the alpine, largely by hibernating for 8 months of the year and largely for having a surprisingly varied array of food in such an inhospitable environment. They live off of grasses, berries, lichens, mosses, and roots and flowers. And live quite well it seems, as they always look chubby, which has one great drawback. They are sought after by bears and wolves. They have a wonderful defense system though. They are constantly on watch and whistle loudly at the first sign of danger, alerting the colony. The prevalence of these "whistlers" as they came to be locally called, in the early days of London Mountain resulted in it's name being changed to Whistler Mountain in the 60's. Hiking on Whistler, Blackcomb or Wedgemount Lake in the summer will almost guarantee an encounter with a chubby, jolly little whistler marmot.

Nunatuk: a rock projection protruding through permanent ice or snow. Old Man's Beard - Vancouver Hiking Terms Their distinct appearance in an otherwise barren landscape often makes them identifiable landmarks.  Nunatuks are usually crumbling masses of angular rock as they are subject to severe freeze/thaw periods.  There is a very prominent nunatuk near the glacier window of the Wedge Glacier.  The glacier has been retreating in the past few years, so this massive nunatuk marks the terminus of the glacier now.

Old Man's Beard(Usnea): The lichen seen hanging from tree branches in much of British Columbia.  It hangs from tree bark and tree branches looking like greenish-grey hair.  A form of lichen, usnea can be found world-wide.  There are currently over 85 known species of usnea.

Post Holing - Vancouver Hiking TermsPiedmont Glacier: formed by one or more valley glaciers spreading out into a large area.

Post Holing: difficult travel through deep snow where feet sink.  A common occurrence while hiking in and around Whistler in the spring and early summer months.  The alpine trails are often covered in snow well into June and some trails into July.  It is not unusual to see hikers in Whistler starting a trail in 25c weather in June with snowshoes strapped to their packs.  Post holing can be very frustrating and arduous.  The hard crust on top of the snow can sometimes support the weight of footsteps, however, often it is not, and one's foot will plunge deep into the snow.

Pressure Ridges - Vancouver Hiking TermsPressure Ridges: wavelike ridges that form on a glacier normally after a glacier has flowed over icefalls.  Pressure ridges are a beautiful and hostile looking feature of glaciers that, when approached, become menacingly huge and dangerous.

Pyramidal Peak: a mountaintop that has been carved by glaciation into a distinct, sharp horn-like shape. The Matterhorn in the Alps is a well know example of this striking phenomenon.

Retreation Glacier: a deteriorating glacier; annual melt of entire glacier exceeds the flow of the ice.  Glaciers around Whistler and Garibaldi Provincial Park are retreation glaciers owing to the past few decades of warming temperatures.Retreation Glacier - Vancouver Hiking

Scree: from the Norse “skridha”, landslide.  The small, loose stones covering a slope. Also called talus, the French word for slope. Scree is mainly formed from the annual freeze/thaw periods of spring and fall, where water seeps into cracks in the rock and expands when freezing.

Seracs: large pinnacles or columns of ice that are normally found in icefalls or on hanging glaciers.

Tarn - Vancouver Hiking TermsTarn: a small alpine lake.  The word tarn originates from the Norse word tjorn which translates to English as pond.  In the United Kingdom, tarn is widely used to refer to any small lake or pond.  In British Columbia however, tarn is used specifically for small mountain lakes.  Around Whistler tarns number in the hundreds and many are so small and/or hidden as to remain unnamed.  Russet Lake in Garibaldi Provincial Park could be called a tarn, however its relatively large size dominates the area and the term lake seems more appropriate.  The nearby Adit Lakes are more accurately called tarns as they are small, shallow and sit in an alpine zone, buried in snow most of the year.
