  • Mount Colden is in the High Peaks of the Adirondack Mountains, New York.
  • Known for its distinctive Trap Dyke, a large crevice running up the center of the mountain which can clearly be seen from Avalanche Lake.
  • There are two maintained trails up Mount Colden: 1) The first approaches from the northeast, passes by Lake Arnold and crosses over several false peaks before ascending to the summit. 2) The second trail, which is steeper, approaches from the southwest, starting from Lake Colden. Both approaches are reached from the popular Adirondak Loj trailhead.
  • Finally, the summit of Mount Colden can also be reached by climbing the infamous Trap Dyke from Avalanche Lake. This approach leads to a long slide and a short bushwhack to the summit. It doesn't follow a maintained trail, is extremely steep in places, and should be taken with caution. The Trap Dyke is also a challenging backcountry ski descent only in the right conditions.
