Tripod Rock
Tripod Rock is a glacial erratic,[1] in this specific case a balancing rock,[2] or perched boulder, located in Kinnelon, New Jersey in the Pyramid Mountain Natural Historic Area. This multi-ton Precambrian gneiss boulder, located near the edge of a long ridge, is balanced on three smaller boulders. Tripod Rock is roughly Template:Cvt long, Template:Cvt wide, and Template:Cvt high, weighing approximately Script error: No such module "convert".. A triangular crest runs the length of its top. The boulder is balanced on three smaller stones roughly Template:Cvt in diameter that raise it above the bedrock by about Template:Cvt at its lowest point. The point of contact between the boulder and its support stones forms an approximate 3-4-5 triangle.
About Template:Cvt northwest of Tripod Rock are three other boulders comprising a triangle. The two larger boulders are partially balanced on smaller stones (see diagram). The apex rock is about Template:Cvt to the northeast. Two smaller perched boulders are located northeast of Tripod Rock (not shown on diagram) measuring approximately Template:Cvt in diameter. No specific calendar alignment has been noted. Tripod Rock stands on a ridge overlooking a long valley where a massive glacial erratic named Bear Rock is located near a brook. Bear Rock was thoroughly excavated for archaeological artifacts during the 19th century, some of which are reported to be owned by museums.Script error: No such module "Unsubst". Bear Rock has a large overhang making it a possible rock shelter.
