Congrats to 4CeasonS on FTF!
This cache is placed in a sand of mature hemlocks, a little bit away from the main ravine trail. You should approach the cache from the "upper parking lot", where the geocache "Gimmie Shelter" is placed. Follow the path all the way down to the ravine floor, then double back to the geocache. As mentioned above, you will need to cross a stream to get to the cache. Either plan to walk through water or balance as you walk across a log.
I was thrilled the first time I came here, discovering a new stand of old hemlocks. Although you could approach this cache from the main road, that way is even wetter than the recommended approach.
