59-ASn-16 (5592-SD) , Mc Grath , Station 24, White Mountain notebook. 154 deg. 54' W., 62 deg. 11' N. (8.96, 3.25). Algal limestone containing corals and an archaeocyathid; believed to be correlative in part with the Holitna group of Ordovician to Devonian age (from original E&R). [Rigby et al., 1994, p. 389 states: "... Sainsbury's geologic cross-section shows his collection to be derived from a medium bedded, light-gray limestone immediately beneath massive dolomitic limestone, which form the rest of the hillslope, upslope to the northwest. Collector, C.L. Sainsbury, 1959 [Fig. 2B]. Aphrosalpingids are quite numerous along the hillslope in the immediate vicinity of Sainsbury's original discovery site [R.B. Blodgett, personal observation]."
