The ASCA returns classic climbing routes to their original danger level by replacing deteriorating old fixed anchors, usually bolts, with modern camouflaged gear. We do not add bolts to make climbs "safer." Climbing is inherently extremely dangerous. For more information click here.
The ASCA has replaced over 7500 old bolts to date in Yosemite and many other areas throughout the U.S., mostly in the western states. For detailed information on the routes click here.
The ASCA has a wide selection of information on bolts, other fixed anchors, and climbing safety. For more information click here.
Help to preserve the cliffs and parks where climbers love to explore the vertical environment. To find out more about how to help, click here.
