Location

Nearly seven thousand feet up, with eleven feet of snow across a typical winter and a moderately wet climate. The spring is right at the road, so access is a matter of the road being open, and at this elevation that is a real question for a good part of the year. Sawtooth National Forest, standard designation. Easley Campground is the camping the record lists.

December through February get the best-months tag here and the water suits cold air. Easley Campground is close by for camping. No fee recorded. Temperature is mild enough to need no caution. The road in winter is the thing to check, since nothing else about access is complicated.
