Approach by driving west from Los Alamos using NM 501 to NM 4 to FR 289 to FR 287.
Hike 2-3 miles to a narrowing of the ridge, following a downhill section. Obsidian flakes litter the path. Large rocks are not found on the path, but can be found by foraging off-path. We met a young man who is mining the area for his knapping projects, returning every few weeks, so stocks of large rocks will dwindle.
