90 Today's long distance geology did not reveal a break in the Supai, but there is probably one here as in the Grand Canyon. Stegmair examined me of the firm-bedded pink sand- stones and found it surrounded on all four sides by the Supai. This looks to me like a channel deposit in the Supai, fine sands laid down by wave action in the previously made channels. When we go up the Plateau we had a fine view of the San Francisco Out, I photo them.
