So, there are several caches located along trails of the eastern part of La Purisma Mission and it can be a bit confusing on which trails to take to get to them. So, this cache was placed to help find a good way to get out there. (On the gravel road to the water tanks is "Gateway to Manzanita Tunnel" which shows the trail to get back to this one). This is a small but reasonably sized container with room for trinkets etc.
