||Dark gray to black siltstone and fissile sooty shale; upper part includes locally fossiliferous limestone beds that are gradational with the overlying Lisburne Group. Restricted to the southwestern corner of the map, largely west of Juniper Creek, where limited exposures crop out in recessive swales beneath the resistant, cliff-forming Lisburne Group. Interpreted as a transgressive marginal marine succession (LePain, 1998). Sections measured south and east of the map area yield thickness estimates ranging from 90 to more than 300 m (LePain and Crowder, 1990); although poorly constrained in the map area, thickness is probably less than 250 m
