Nanatuk Sea to Sky Hiking Terms
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.

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). 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. 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. The elevation gain makes a tremendous difference when carrying a heavy backpack and unprepared for the exertion. There is hardly a section of the trail that is not steeply uphill. The first 15 minutes takes you into the deep forest and then across Wedgemount Creek. This crashing creek can be heard from quite a distance and gives you a hint of the steepness of the trail to come.

Glossary of Hiking Terms Squamish Hiking Terms
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.
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.
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: 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.
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.
Snow Bridge: a structure of snow that fills in an opening such as a crevasse or a creek. Often formed by a snow drift which begins as a cornice and grows into a snow bridge. In the summer, what was a small creek crossing, in the winter will be an often precarious snow bridge. Though, not terribly dangerous, this often encountered type may drop you in an instant, thigh deep in freezing creek, and armpit deep in snow.
Tarn: 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.
