The Kiowa Formation or Kiowa Shale is a Cretaceous geologic formation in Kansas, diminishing to member status in Colorado and Oklahoma. In Colorado, the Kiowa Shale was classified as a member of the now abandoned[2] Purgatoire Formation.[1] In the vicinity of Longford, Kansas, the local Longford member comprises thinly bedded siltstone, clay, polished gravel, lignite, and sandstone suggests a river and estuary environment.[3]
In other regions, the same strata is called Skull Creek Shale, named after its exposure in Skull Creek, in Wyoming.[4]

Use of Purgatoire formation in Tucumcari-Sabinoso area, Guadalupe, Harding, San Miguel, and Quay Cos, northeast NM in the Palo Duro basin and on the Sierra Grande uplift abandoned [should read "areally restricted"]. Term Purgatoire abandoned. Both Lytle and Glencairn are mappable at 1:24,000, and they are separated by a disconformity--the most significant break in the Lower Cretaceous. Authors believe there is no reason to retain them as member rank or to raise the Purgatoire to group rank.
