1. MESSAGE …. Is the large fold you see an anticline or a syncline? Explain.

2. MESSAGE …. Observe the two igneous dikes. Based on the reading and your observations, which color is the youngest? Explain.

3. LOG …. Post a picture at or near the coordinates. This picture is your log signature.

OPTIONAL - Please respect the time and effort involved in finding and 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.

THANK YOU Mark W. Carter for permission to use your book for this earthcache.
THANK YOU Lillian for permission to place this earthcache along the Blue Ridge Parkway.

FOLDING
Rocks are deposited as horizontal strata. However, when compressional forces deform the rock, folds result. The greater the compressional forces, the steeper the fold.

Anticline - An arch-like shape with its oldest layers at its core. HINT: Think anthill.
Syncline - An arch-like shape with its youngest layers at its core. HINT: Think sinking.

IGNEOUS SILLS AND DIKES
Hot magma squeezes through cracks in rocks and then cools. The intrusion is always younger than the surrounding rock. If the intrusion moves sideways along weaknesses between rock layers, it is called a sill. If the intrusion moves upwards and cuts across rock layers, it is called a dike.

OUTCROP
Here you can observe an excellent example of a large fold. We were only able to clearly see it when viewed from a short distance away. You will also see two different colored dikes that cut across the layers.
