Selway-Bitterroot Frank Church Foundation hosts author Aaron Theisen for a presentation covering his latest guidebook featuring 125 hikes in Glacier National Park and Western Montana recreation areas, with outings to suit all ages and fitness levels.

Weekend-worthy wilderness hikes await explorers in: the 100,000-acre Cabinet Mountains Wilderness, where alpine lakes hide among amid sheer shelves of rock; the Scotchman Peaks, which house millennia-old trees beneath their rugged, brushy summits; the shallow, grass-fringed pools of Ten Lakes Scenic Area, just shy of the Canadian border in northwest Montana; and the jeweled basins of the Seeley-Swan Valley.
