It ranges in thickness from 2,000 to 2,700 feet.The lower Pierre Shale consists primarily of the Sharon Springs Formation, which has been correlated regionally throughout Kansas, Colorado, Nebraska, Wyoming, South Dakota, and North Dakota.

Shale beds are abundant near base. Contains large flow casts about 20 ft above base. Contains fossil pelecypods in lower part of upper shale and at top of lower sandstone. Thickness 180 ft. Entire mapped formation is considered Pierre Shale by one [anonymous] authority. Overlies Pierre Shale (Upper Cretaceous).For Pierre Shale the calculation gives ρ 2 = 6.3 μm/s, while for sandstone a commonly cited literature value of approximately ρ 2 is 10-11 μm/s (Straley et al., 1997). Dunn et al. (2002) have shown that there is considerable variability of ρ 1 and ρ 2 in siliclastic rocks and our computed value is therefore reasonable. Interpretation of ...A third known specimen of the ammonite Rhaeboceras burkholderi Cobban, 1987, has been discovered in the upper part of the Pierre Shale of early Maastrichtian age (Late Cretaceous) Baculites eliasi zone of Dawson County, Montana.
