Title: Oil shale of the Rocky Mountain region
First published: 1923
Description: The shales of the Rocky Mountain region have been the subject of a considerable amount of study by geologists of the United States Geological Survey, and several reports on them have been printed, but most of these reports, although several times reprinted, are no longer available for distribution. Therefore in the present report an attempt is made to include all of this information, together with that collected by the writer and others since the publication of the last previous report on oil shale.--Page 8.
