Inside a glacier cave in Oregon’s Three Sisters Wilderness
In central Oregon, three volcanic peaks in the Cascade Range are the central feature of the Three Sisters Wilderness area. Fourteen glaciers cover various parts of the wilderness area’s 286,708 mountainous acres, and caves form below the ice of some of them. Some hikers may miss the cave entrances completely. But an experienced guide might be just the thing if you’re interested in safely viewing these seasonal caverns and grottos. This time of year, prepare to get wet if you do.
