This cache is part of the WERDAVE 80 for 80 series celebrating WERDAVE's birthday and his extensive contributions to cache hiding, especially on the trails and in the parks around the Santa Clara Valley.
The cache is hidden on the Limekiln Trail in Sierra Azul OSP. You're looking for a tiny rock cavern on the uphill side of the trail. It's covered with moss that my plant app identified as "red-stemmed feathermoss". I considered whether this is a feathermoss robe, dress, cloak, blanket, or beach coverup, and decided on robe. Please let me know if you disagree! The cache is a small Snaplock with camo appropriate to a rock wall.
Sierra Azul OSP is open one-half hour before sunrise until one-half hour after sunset. Happy hunting!
