Summary:
Pg. 35 and passim. Damnation limestone. Most distinguishing feature is bright buff color to which it weathers. At type locality conisists of play, dull-gray to tan-gray, fine-grained, fairly pure limestone in beds averaging 1 inch in thickness, with irregular bedding surfaces, and with a few flakes and nodules of buff clay irregularly distributed both between and within the limestones. Thickness averages 25 feet. Overlies Wolsey shale (Middle Cambrian) and underlies Nannie Basin limestone. Forms the steep slope at foot of the cliffs on southwestern side of Pagoda Mountain, in NE/4 sec. 9, T. 22 N., R. 13 W. This slope lies at head of Damnation Creek, which flows southwest. [Age is Middle(?) Cambrian.]
