Drumlin Sea to Sky Hiking Terms
Drumlin: a ridge or hill formed from glacial debris. From the Gaelic “ridge”. Large drumlins often mark the final edges or border of a glaciers path. Drumlin's are generally about 1 to 2 kilometres long and between 100 and 500 metres wide. Most drumlins are less than 50 metres high. Click the image below to see an aerial video of the drumlin flanking the Overlord Glacier near Russet Lake in Garibaldi Provincial Park.
Russet Lake is a fantastic alpine lake that lays at the base of the Fissile. The Fissile is the strikingly bronze coloured mountain so visible from Whistler Village. From the Village look into the distance at the Peak to Peak hanging between Whistler and Blackcomb and you will see the Fissile. Its pyramid shape in the distance perfectly separates the two mountains.
Though Russet Lake is not terribly impressive in terms of size or colour, the valley around it is remarkably beautiful. The colours change from moment to moment in and extraordinary way. The distinctive colour of the Fissile and the stark grey of the mountains around contrast amazingly with the blue of the lake and green grass in the valley. So many different factors fill the place with colour.
Glossary of Hiking Terms Squamish Hiking Trails
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.
Class 1,2,3,4,5 Terrain Rating System: a rating system to define hiking, scrambling and climbing terrain levels of difficulty. Separated into 5 levels of difficulty ranging from class 1 to class 5. Class 1 is easy hiking, to class 5 terrain, which is very difficult terrain requiring ropes. Class 5 Terrain: technical climbing terrain. Rope required by most climbers. If you are looking at a vertical rock wall, you are effectively looking at class 5 terrain. A typical gym climbing wall is replica of a class 5 terrain rock wall. Class 4 Terrain is one grade easier than class 5 terrain. Class 4 terrain is defined as very steep terrain which rope belays are recommended. Though experienced climbers will find class 4 terrain relatively easy and safe to navigate, novices to climbing will find class 4 terrain difficult, frightening and dangerous. The Lions in North Vancouver requires climbing a short section of class 4 terrain to reach the summit.
Col: 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.
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.
Couloir: a narrow gully often hemmed in by sheer cliff walls. From the French word meaning passage or corridor. Often a couloir is a fissure or vertical crevasse in a mountain. Couloirs are often partially filled with scree and when covered in snow form a dramatically beautiful, near vertical channel in mountains. Couloirs are well loved by extreme skiers and snowboarders and feature in most extreme skiing/snowboarding movies.
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.
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.
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.
Transverse Crevasses: form perpendicular to the flow of a glacier. These are normally found where a glacier flows over a slope with a gradient change of 30 degrees or more.
Valley Glacier: A glacier that resides and flows in a valley. Many glaciers around Whistler and in Garibaldi Provincial Park are valley glaciers. The Wedge Glacier above Wedgemount Lake flows down the valley from Wedge Mountain. When you reach Panorama Ridge in Garibaldi Provincial Park, valley glaciers dominate the view along with the unnaturally brilliant Garibaldi Lake below.
Waterbar: a ditch that carries water from one side of a road to the other.
