From the trailhead, the road will pass by three powderhouses on the way to the cache. The first one is an older style, with a peaked roof with wooden beams. This one appears to have been used as a camp at some time, with a hole in the roof for a chimney pipe and a tv antenna mounted to the roof. The later two are newer styles with concrete roofs. It's unusual for a mine with 4 active shafts to have 3 powderhouses. The first one may have been abandoned due to location and age and the newer ones its replacement.
After the cache, take the RR grade to the west back. It will come out (just west of trailhead) by the #2 boilerhouse and chimney foundation. Take the road uphill to find the #2 hoisthouse and on to the #2 shafthouse.
