This historic 15’ rock outcrop is a wonderful example of Ely greenstone, a “rare ellipsoidal lava flow formed beneath primeval seas 2.7 billion years ago.” It is volcanic in origin and there are very few specimens like this in the world. It is easily accessible 24/7 and can be seen on the north side of Main Street in the northeast part of town.
Ellipsoidal lava is also known as "pillow laval" and is any lava characterized by pillow structure and presumed to have formed in a subaqueous environment.
