Historical:Kiser Creek Member
H. B. Willman and John C. Frye
The Kiser Creek Member of the Baylis Formation (Frye et al., 1964, p. 4, 10), the upper member, is named for the East Branch of Kiser Creek, a tributary of which exposes the type section.
The type section for the Kiser Creek Member is the same as that of the Baylis Formation, an exposure and small pit along a branch of Kiser Creek (NW SW SE 31, 4S-4W).
The member constitutes the greater part of the formation and is dominantly sand and clayey sand, as described for the formation. The sands and clays of the Kiser Creek Member differ from glacial sands in their uniformity, lack of carbonates, distinctive clay mineral assemblages, and the absence of the variety of heavy minerals that characterizes the glacial deposits.
