Stairs is located in the Central Coast region of California, on Vandenberg Air Force Base (VAFB). This site is located within the Vandenberg State Marine Reserve. The site's location on VAFB largely restricts human use, although the reef is occasionally used by military personnel for fishing. This gently sloping site consists of moderately uneven terrain, containing few cracks and folds.
