This Earthcache is designed to show you an example of the erosive forces at work in Sedona.
Access is via the Munds Wagon Trail, or or Schnebly Road. Parking for the Munds Wagon Trail is available at the end of the paved section of Schnebly Road.
Parking in the Red Rocks area, requires a pass for parking. You can get a Red Rocks Pass at a kiosk at the parking area, or from the Ranger Station in Sedona.
You can drive the unpaved section of Schnebly Road, but a 4x4, high clearance vehicle, mountain bike, or ATV is recommended.
Erosion is the process by which soil and rock are removed from the Earth's surface by wind or water flow,and then transported and deposited in other locations.
Erosion occurs through a variety of processes, such as:
Rainfall
Rivers/Streams
Glaciers
Coastal Lakes/Oceans
Freezing and thawing
Wind Erosion
Exfoliation
The coordinates will take you to an area of slickrock, where there are several potholes.
The actual work of abrasion is considered to have been done either by hard grains of sand held in suspension by the rapidly flowing water; or by large boulders, called "grinders," in the bottom of the pothole, that were agitated constantly by the currents swirling around inside. The tiny grains in the rapid currents are thought to have gradually worn down the rock into a depression, that was deepened by the motion of the grinders. The longer this erosion occurs, the deeper the pothole
To log this Earthcache, email me the following:
1) How were these potholes formed
2) What is contained within the potholes which may help with erosion
3) What is the diameter and depth of the pothole at the starting coordinate, and what does this tell you about the age of this pothole in comparison with the others
OPTIONAL: Post a photo of you and your GPS
