Summary:

Hackberry shale of Cimarron group. The shale underlying Big Basin sandstone member of Greer formation has previously been called Hackberry shale, a name that is inapplicable because of prior use for an Upper Devonian division of Iowa.
[GNC remark (US geologic names lexicon, USGS Bull. 896, p. 894): There is no record of any other name having been introduced to replace this one.]
