We have been examining Ireson Hill and found this unusual 10-15 cm diameter rock- called Passagassawakakeag !
The shape is an almost perfect Dreikanter. That's a German word for a sample in desert or periglacial environments formed by the abrasion of blown sand. Dreikanters typically have a pyramid shape with flat wind-abraded facets.
