Join San Juan Mountains Association and San Juan National Forest on an interpretive hike to learn more about the geology of the Pagosa District area. These hikes, led and presented by geologist Dave Bouquett, will be in an area of the San Juan National Forest rich with evidence of earth's geologic history from some of the area's oldest metamorphic rocks, to Cretaceous seaways, to Tertiary volcanoes, to modern glacial deposits.

This Canyon Rocks! - Piedra River Trail
One of the most popular hiking trails in the Pagosa area for families and experienced hikers alike, threads through a great mix of river canyon, meadows, and forest. Shortly after leaving the parking area, the trail drops moderately into a beautiful, narrow sandstone canyon through which the Piedra River cascades over rocks and boulders in its path. The shady cool of the tree-covered canyon is a welcome relief on a hot summer day. Rocks and boulders cover much of the path so sure footing and appropriate footwear are a must. The bottom of the canyon then opens into a serene riparian meadow through which the trail meanders. Approximately 2.9 miles from the trailhead is the second of two steel pedestrian bridges on this hike, this one crossing the Piedra River. Nearby some of the oldest rock in the area is found. Though the trail continues, this will be our planned turn-around point as we return back up the same canyon trail we descended. Hike time is approximately 4 hours total, 6 miles round trip, and a 600 ft. vertical ascent round trip. We will stop for approximately ½ hour along the trail to eat, so pack your own lunch.
