Post Holing Sea to Sky Hiking Terms
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. Often as late as July, you will find yourself post holing your way to the summit of Panorama Ridge (pictured below). The ridge keeps much of the approach in shade and the snow melts much slower than the sun facing valley.
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. Another Whistler area trail you will encounter post holing well into July is Wedgemount Lake. It is not unusual to find the lake frozen over early and late in the otherwise warm summer months.
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).
The video below shows Rethel up close then a panorama of the valley to include Parkhurst, Wedge, Weart and Cook.
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 the many beautiful 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 an amazingly 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.
Glossary of Hiking Terms Squamish 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.
Highpointing: the sport of hiking to as many high points(mountain peaks) as possible in a given area. For example, highpointing the lower 48 states in the United states. This was first achieved in 1936 by A.H. Marshall. In 1966 Vin Hoeman highpointed all 50 states. It is estimated that over 250 people have highpointed all of the US states. Highpointing is similar peakbagging, however peakbagging is the sport of climbing several peaks in a given area above a certain elevation. For example, a highpointer may climb the summit of Wedge Mountain, the highest peak in the Garibaldi Ranges, then move to another mountain range. Whereas a peakbagger may summit Wedge Mountain, then Black Tusk, Panorama Ridge, Mount Garibaldi and many more high summits in the region.
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 quite 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..
Ice Mill: a hole in the glacier formed by swirling water on the surface. These can be large enough for a human to slip into.
Krummholz: low-stunted trees found in the alpine. From the German “twisted wood”. Continuous exposure to hostile, alpine weather causes trees to form in bizarre and stunted ways. Many types of trees have formed into bizarre krummholz trees including spruce, mountain pine, balsam fir, subalpine fir, limber pine and lodgepole pine. The lodgepole pine is commonly found in the alpine regions around Whistler.
Longitudinal Crevasses: form parallel to the flow of a glacier. These are normally found where a glacier widens.
Moat: is a wall formed at the head of a glacier. Formed from heat reflected from the valley wall.
Moraine (lateral): formed on the sides of a glacier. Moraine (medial): the middle of a glacier. Also formed as two glaciers come together or as a glacier moves around a central peak. Moraine (terminal): formed at the terminus of a glacier. Moraine (ground): the rocky debris extending out from the terminus of a glacier.
Nunatuk: a rock projection protruding through permanent ice or snow. 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.
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.
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.
