Schriebers Meadow Cone produced thick dark-reddish-brown to yellowish-red scoria that blankets the sides of the Sulphur Creek valley near and southeast of Schriebers Meadow. Near Schriebers Meadow the scoria deposit is thickest on the north valley wall and it decreases in grain size and thickness within short distances. Within of the cone the scoria fragments are as much as in diameter and the deposit is thick; to the northeast the fragments are of sand size and the deposit is no more than thick.
