Longmont Reservoir Area (aka Buttonrock) Rock Climbing

Also located west of Lyons, this area is cousin to the South Saint Vrain (SSV). Like the SSV there are both trad and sport routes on a variety of features. Rock quality varies from superb to choss. One of Buttonrock's centerpieces is the classic River Wall. This steep wall has steep cracks alongside of both technical and pumpy sport routes. Well-known climbers from Boulder and around the Front Range developed this area in the last three decades. The best climbing season is whenever it isn't precipitating, possibly year-round as the aspect of the formations is diverse. River Wall in particular has midday sun, but is often chilly due to breeze off the river. The Falcon guide to Lyons area covers both Buttonrock and the SSV.
