Description:

This classic Obsidian hike will take us up a short section of the PCT beyond South Mathieu Lake to some excellent views of the Cascade Volcanic Arc. From the top of Yapoah Crater there is an excellent view of recent lava flows and glacial features near North Sister and Collier Cone. Climbing the volcanic cone is optional. On the return loop we will visit North Mathieu Lake, one of the most unusual lakes in the area, partly formed by a lava dam. Each hiker will receive a geologic map of the area. We will almost certainly encounter some large patches of snow. Hiking poles (at least 1) are very helpful in maintaining balance when crossing these snow patches. I highly recommend them. How much snow remains to be seen.
