Spur Canyon

verified ACA 3B Moderate flood risk Lovell, WY

Half day limestone canyon in an unexpected location on the Wyoming Montana border. Four short rappels and a cave exit.

First descended by Jeff Baird in the early 2000s. The optional one mile shuttle saves an uphill exit road walk. Rattlesnakes present spring through fall. Cell coverage nonexistent; the access road from Lovell is rough and washboarded.
