On Peter's request, I have put together this little guide to the structures I found at the Whipple Hill Conservation Area. All labels are approximate. Click on the image for a higher resolution of the satellite photo.
A. Skyline Dr. is where I parked my car.
B. Area of the pyramid stones around two boulders.
C. Enormous stone heaps.
D. Earthen dam with large rocks.
E. Clearing with edge heap. (note: this clearing might technically be part of the adjoining Locke Farm Conservation Area)
F. Three more stone heaps behind homes.
