A pegmatite dike 3-4 feet wide and approximately 40 feet long. The dike showed strong segregation of minerals with 12-18 inches of massive white quartz in the middle and pink potash spar at the edges. Books of altered chloritic biotite up to 2 inches in diameter occur within the feldspar. Magnetite or ilmenite and a few small brownish crystals up to 1 inch long (allanite).
