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 on a glacier.

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 experienced hikers on their way to Wedge Mountain and Mount Weart. Extreme caution is always needed and if you don't know how to remain safe while navigating a glacier, you should avoid doing so. 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.
