The cache is part of the Snow Mountain Challenge series. The caches in the series are:

Inside this container you will find one of the numbers on the combination lock that is on the Snow Mountain Challenge cache.
I placed this geoache while working on the Snow Mountain Challenge series. As I approached the rocks the song "Rock Lobster" was running through my mind. It sounded appropriate to me since the cache is located in rocks and is near the Scorpion's Lair. And a Lobster is basically a water scorpion minus the stinging tail.
