Geocache Description:

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.

Logging requirements:

From the viewing location, what type of fault is this fault?
Are the rocks of the zone tilted or not?
Please take your picture at the trail marker just up from the fault where you will be turning left. Please
do not post a picture of the fault as it would be too revealing.

Please do not post your answers in your logs. Please send your answers to the earthcache owner via with the title of the Earthcache and GC number. If you log the cache without sending the completed logging requirement, you will be contacted to do so, and if not sent within a reasonable amount of time 1-2 weeks, you logs will be subject to deletion.


The creation and behavior of faults, in both an individual small fault and within the greater fault zones which define the tectonic plates, is controlled by the relative motion of rocks on either side of the
fault surface. Because of friction and the rigidity of the rock, the rocks cannot simply glide or flow past each other. Rather, stress builds up in rocks and when it reaches a level that exceeds the strain threshold, the accumulated potential energy is released as strain, which is focused into a plane along which relative motion is accommodated — the fault

Local Information and History:

The Green Valley fault is located in Green Valley with a smaller Cordelia Fault running through the Park from Green Valley hill, through the lake and the far northern slope of the park, where we are currently
standing. Looking northeast, you can see the fault as it leaves the Park and crosses onto the northeastern side of Rockville Road. The fault is deemed to be active even though movement is unlikely.
