EARTHCACHE REQUIREMENTS
Each cacher must send his/her own answers BEFORE logging a find. Enjoy the journey (learning adventure) as well as the destination (smiley earned). Remember to take only pictures and leave only footprints. To get credit for this Earthcache, complete the following tasks:
1. MESSAGE …. a. Describe the sandstone feature you find at Waypoint S1. / b. Is it a primary or secondary sedimentary structure?
2. MESSAGE …. a. Describe the sandstone feature you find at Waypoint S2. / b. Is it a primary or secondary sedimentary structure?
3. MESSAGE …. a. Describe the sandstone feature you find at Waypoint S3. / b. Is it a primary or secondary sedimentary structure?
4. MESSAGE …. a. Describe the sandstone feature you find at Waypoint S4. / b. Is it a primary or secondary sedimentary structure?
5. LOG …. Post a picture of another sandstone rock that you found interesting anywhere along the trails. Label picture with the trail color where you took your picture.
OPTIONAL - Please respect the time and effort involved in creating this earthcache by adding A and B to your log.
A. JOURNEY OF THE MIND ... Science explains what we observe. Relate (in your own words) something you found interesting in the reading. This adds to your learning adventure and your log.
B. JOURNEY OF THE HEART ... Art shares our personal experience of what we see. Share something special you found on site, and why it is special to you. This is a memorable addition to your log and will make other hearts smile.
Journeys of Heart and Mind ...

BURIED IN SAND
Sandstone is formed from cemented grains of sand. Because sandstone is a coarser material than shale or limestone, it rarely contains smaller fossils. Remains of large trees and animals (dinosaurs) are much more likely to be found. The sand forming the sandstone here was deposited 320 million years ago during the Pennsylvanian Period. At this time, Western Pennsylvania was a tropical river delta along an inland sea. The rocks in this park are all sandstone.
SANDSTONE FEATURES
Primary sedimentary structures are produced at the same time as the sedimentary rock in which they occur. Examples include stratification (layering) and cross-bedding (layering at an angle). Secondary sedimentary structures form after deposition.
At one of the waypoints, you will be observing chert. Most of the stone artifacts are projectile points made of Onondaga chert found in the glacial outwash sediments of the Allegheny River.
