Ephraim Elk Valley is an out-and-back spurring off Crow Creek Road that takes you just past the Elk Valley Marsh. The marsh, a 200-acre high-altitude wetland bordered by grassland and forest, is recognized as an Idaho birding community site. The area is a nesting and molting area for Canada Goose and dabbling ducks. Camping is limited to a couple of sites at the top of the hill at the start of the trail and one at the end. The trail traverses a burn scar. Be aware of potential fallen trees on the trail.
