(description from Blodgett, 1978, M.S. thesis; [Holmer et al., 2020 p. 144 provides the following description: The University of Alaska (UA) Museum locality A941 (Fig. 1) is from the base of Section D of Blodgett (1978). The section is situated in the Yukon Territory (latitude 65º05.2´N, longitude 140º59.56´W) and was measured in a small cliff composed of thinly bedded dark grey, petroliferous, micritic limestone. The cliff is located on the south side of Hard Luck Creek (also known as Harrington Creek), in its upper reaches approximately 0.805 km (0.5 mile) east of the Alaska–Yukon boundary, at the point where the creek makes a sharp bend to the north upstream. The total height of the section is 4.3 m (14 feet). The UA Museum locality A­941 represents the basal 1.22 m (4 feet) of section D. Conodonts from this locality include the age­ diagnostic Polygnathus inversus Klapper & Johnson of middle Emsian age (Blodgett 1978).
