If you've never been there, it is worth the hike. It is full of wildlife and lots of "varmint tracks" along the way. Several quartz rocks line the path.
There are several routes available to the virtual cache. I chose to park at the south entrance. Take water and enjoy the scenery.
This will lead you to a virtual cache of the Pennington Mine Tunnel. The horizontal mine shaft was blasted, and then tunneled out of the side of a mountain by some miners from famed Cripple Creek. The Pennington brothers bought the mine in 1904 for $5,000 and dubbed it the Gold Coin Claim. The mine produced a very minimal amount of platinum or gold. It is a horizontal mining shaft that measures six feet high and four feet wide. It is approximately 110 feet long. Take a good flashlight to look inside.
