Tripod Rock is a hundred seventy ton "glacial erratic" which perches atop three smaller boulders on the side of Pyramid Mountain, Morris County, NJ. It has been considered a spiritually significant site by local people for hundreds, if not thousands of years. The Rock is the largest of this type in the eastern USA. It sits somewhat south of the terminus of the last major glacier, thus, it dates back at least two glacial cycles, or over 100,000 years. The local legend is that it was levitated into position by Native Medicine.
