Abstract: Napier Drilling Company of Dallas, Texas drilled 53,998.0 feet for exploration purposes, under Contract No. AT(05-1)-256. This footage was drilled in 508 holes during the period from June 21, 1954 through May 13, 1955.

Introduction: Studies of uranium-vanadium occurrences in the Four Corners region show that, with the exception of the Lukachuai area, all of the major deposits in the Morrison formation are grouped around the various igneous masses which are scattered irregularly throughout the Colorado Plateau. The pattern of deposition varies from mountain group to mountain group and each will be described separately. Maps accompany this report to supplement the descriptions of ore occurrences in the vicinity of the La Sal, Abajo, Carrizo, and Henry mountains. Elsewhere, it is believed that a written description will suffice.

Report discussing stratigraphic studies of the Triassic and associated formations in northern Arizona and southern Utah. The programs of study included are "(1) regional stratigraphic descriptions and correlation of units, (2) sedimentary structure studies, (3) pebble studies, and (4) sedimentary petrology."

From abstract: "Stratigraphic studies of the Triassic and associated formations have been made in southeastern Utah and adjoining parts of Colorado and Arizona. These studies have followed five principal lines of investigation: regional stratigraphy, sedimentary petrology, pebble studies, sedimentary structure studies, and lithofacies studies."
