RVET (RockVille Earth Trail)
As an earthcache, there is no “box” or “container” to discover. The Rockville Regional park is located in the City of Fairfield. There is a main entrance and free parking, but there is an Entrance fee of $3.00 dollars. This is a very popular hiking & biking park. There is also additional fee information at the pay station. The park is Dog friendly but will require an additional fee for your 4 legged friend.

Please take you picture away from the mouth of the cave as it will give away too much information.
Please do not post your answers in your logs. Please send your answers to the earthcache owner via geocaching.com with the title of the Earthcache and GC number.

Geology:
Caves, in this case a very large Gas pocket, like other pockets on vertical faces in this park are a result of active gas breaking through molten lava that is still pliable enough to "blow out" horizontally under the pressure. The cave and the supporting hill are of basalt, but you can see other features like layers and striations, and bumpy textures that look like bubbles. Some areas are very smooth, where others are jagged as if torn. You can also see horizontal pockets on the ground.
This area at the cave and the approach are very steep. in the rainy season, this area is very slippery, and you may want to avoid the approach from a direct frontal asault, but rather use the small switch backs and approach from the side.
Local Information and History:
Speaking with the Ranger staff, this cave was occupide by the homless and even had a picnic table crammed in the cave. It has since been cleared, and is a feature of this end of the park noted by trail signs. Very popular place to go to see the vastness of the park, and the elevation allows to to get that Dragon's eye view.
