Geocache Description:

Parking is located near the coordinates listed. It is easily seen at the above coordinates. A picture is provided to show you what to look for. No permission is given to go on the land where this feature is at!!!

Pete's Pot is the local name for this poorly known crater. Craters are known to form from two different processes; impact of meteors with the Earth, and explosive volcanism. Many of these features are very large, but many are small as well. Volcanic craters can usually be distinguished from impact craters by their irregular shape and the association of igneous rock and other volcanic material. Clusters of young volcanic rocks (generally less than 2 Ma) extend from northwestern Arizona through southwestern and west-central Utah. These units consist of a bimodal assemblage of mainly basaltic rocks and less voluminous rhyolitic rocks. In southwestern Utah, several clusters of mostly basaltic rocks are oriented northeast-southwest, subparallel to the Basin and Range Province and Basin and Range-Colorado Plateau transition zone margin. This package of volcanic rocks consists of series of basaltic flows and vents that do not seem to coincide with mapped faults. Rather, some vents lie adjacent to major faults, such as the Hurricane and Sevier faults, localized on the footwall or hanging-wall block, but not appearing to have used the fault as a conduit for magma. Cinder cones and mounds, which generally form alignments parallel to the faults, appear to have formed along steep joints. Take a look at the rocks surrounding the road and give your best guess as to what type these rocks are: igneous, metamorphic or sedimentary. Using this imformation, state what caused this crater. Provide an estimate of the width and length of the crater. Using this information, tell me what type of volcano you expect created this crater, if it is volcanic in origin. As always, an optional requirement is to take a picture with your gps at the posted coordinates. Please don't post any of your answers on your comments as they will be deleted.
