Unfortunately, other than the two predecessors to this story, no non-technical geologic publications about the Park exist. The references below are all in professional journals, but can be understood by interested readers with elementary geologic knowledge. Several are about areas in southeastern Wyoming and central Colorado from which information has been drawn as a basis for this story.
