Southwest Idaho context

Southwest Idaho splits across the Snake River. South of the river is Owyhee high desert — sage flats, slickrock canyons, and a million-plus acres of BLM. North is the Boise National Forest, with mining-era roads, ponderosa, and quick out-of-Boise access. Most weekend trips work off Boise, Mountain Home, Marsing, or McCall.
