A spectacular panoramic view of the southern half of the Pinedale quadrangle is obtained looking northward from Interstate Highway 40, particularly from the New Mexico State travelers’ rest stop near the Shell Oil Company’s Ciniza Refinery, 28.5 kilometers (17.8 miles) east of Gallup. A west-trending escarpment, 200 meters high, of massive red sandstone, rises above a broad valley, its continuity broken only by a few deep and picturesque canyons in the western half of the quadrangle. The escarpment is formed by the eolian Entrada Sandstone of Late Jurassic age. The Entrada unconformably overlies the Chinle Formation of Late Triassic age, which occupies the valley below. The Chinle Formation consists of cherty mottled limestone and mudstone of the Owl Rock Member and underlying, poorly consolidated, red to purple fluvial siltstone, mudstone, and sandstone beds of the Petrified Forest Member. The pinyon- and juniper-covered bench that tops the escarpment is underlain by the Todilto Limestone. A quarry operation, located just north of the Indian community of Iyanbito in the southwestern part of the quadrangle, produces crushed limestone aggregate for highway construction and railroad ballast. Beyond the escarpment to the north and rising prominently above it, is the northwest-trending Fallen Timber Ridge. Near the west side of the quadrangle lie the peaks of Midget Mesa, and Mesa Butte, the latter of which has the highest altitude in the area at 2,635 meters (8,030 feet) above sea level. The prominences are capped by buff-colored resistant beds of the Dakota Sandstone of Late Cretaceous age, containing some interbedded coal. These beds unconformably overlie the uranium-bearing Morrison Formation, which consists of red, green, and gray shale, orange feldspathic sandstone, and green tuffaceous mudstone, deposited in ancient lakes, alluvial fans, and rivers during the Upper Jurassic Period. Thick, crossbedded, white beds of the Cow Springs Sandstone, derived from ancient windblown desert sands, underlie the Morrison. In the northern part of the quadrangle, the Dakota Sandstone is overlain by gray Mancos Shale and yellowish-gray Two Wells and Gallup Sandstones that were deposited in Late Cretaceous seas. Unconsolidated deposits of Quaternary age are found throughout the quadrangle in talus, slope wash, fans, valley alluviums, pediments, and as windblown sands in dunes and blanket deposits. The strata conform to the regional dip of about three degrees to north, except where they are down-folded some 200 meters along the Pinedale monocline, whose limbs follow a sinuous west-northwest trend across the northern half of the quadrangle. The monocline is beautifully exposed at Pinedale, where it shows as much as 20 degrees dip on the pine-studded bare rock slope of the Two Wells Sandstone. A north-plunging broad anticline and accompanying syncline is developed in the east-central part of the quadrangle but dies out against the monocline. A minor fault, with barely 3 meters of vertical displacement, extends several kilometers westward across the Todilto Limestone bench. A large landslide mass, 1.5 kilometers long by 0.7 kilometers wide occurs in the Mancos Shale west of Pinedale. Exploration drilling for uranium in the Morrison Formation has been extensive in the quadrangle, particularly north of the monocline, which adjoins the Old Church Rock mine area, west northwest of the quadrangle. Purpose: The Pinedale quadrangle is one of sixteen 7 ˝-minute quadrangles included within a block covering parts of the uranium mineral belt between the Ambrosia Lake Uranium Mining District near Grants, New Mexico, on the east and the Church Rock Mining District near Gallup on the west. Study of the mineral belt was proposed and defined as a cooperative project between the Atomic Energy Commission (AEC) of the U.S. Department of Energy and the U.S. Geological Survey (USGS), to provide geologic framework, including geologic quadrangle mapping and studies of uranium ore bodies in the area. Geologic field mapping and studies were initiated by the USGS in 1967. The rationale for the project was to provide geologic quadrangle maps in a timely manner that would assist exploration and mining companies, the AEC, and other government entities in exploration and development, and in understanding the geologic parameters of the ore deposits. The quadrangle maps were initially released as quickly as possible as U.S. Geological Survey Open-File Reports with abbreviated map explanations. Most were published later with more complete and detailed map explanations. Supplemental_Information: Geologic compilation was done on published USGS 7 ˝-minute topographic quadrangle maps at a scale of 1:24,000 (2”= 1 mile), with the aid of stereoscopic color and black and white aerial photos at a scale of approximately 1:20,000. Much mapping was done in the field by observation, with contacts and structures drawn on prints of aerial photos or directly on prints of topographic maps. Geologic information was also recorded in field notebooks. Transparencies of the aerial photos, as well as positive prints, were employed in the PG-2 Stereo-plotter in the laboratory. Some mapping was done by plane table in rugged terrain. The plane table was also used to measure detailed stratigraphic sections. Generally, points on the map are located, horizontally and vertically, within three meters. Structure contours on the base of the Dakota Sandstone were constructed from surface exposures and, below the surface, from abundant and detailed radiometric logs of exploration companys’ drill holes in the northern part of the quadrangle. Although not shown, drill holes are generally located horizontally within 30 meters, and within 3 meters vertically. The locations and identity of drill holes are not published because they are company classified information.

Robertson, directly from field and laboratory observations, mostly in 1971-1973, but with later additions and modifications. Compilation was essentially complete in 1995. The author was aided greatly by the insights and contributions of earlier geologists, many of whom are acknowledged in the list of References Cited. Interim field assistants helped with geologic traverses, plane table mapping, map compilation, and measurement and description of formations. Timothy Jackson assisted in many ways; he also compiled a preliminary regional structure contour map of the base of the Dakota sandstone, which was utilized with refinements on this map. This geospatial database of the mapping was created by Anne Donovan, Marcus Lieberman, Darren Van Sistine, and Diane E. Lane (map editor).

The author and a USGS map editor reviewed the digital output independently. Logical_Consistency_Report: Map elements were visually checked by the editor for overshoots, undershoots, duplicate features, and other errors. ARC/INFO software was used to create topological relations among features. Completeness_Report: Geologic map units were collected and digitized at appropriate resolution for portrayal on a base at 1:24000 scale. Data are complete: no features were eliminated or generalized. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Generally, points on the map are located, horizontally and vertically, within three meters. Structure contours on the base of the Dakota Sandstone were constructed from surface exposures and, below the surface, from abundant and detailed radiometric logs of exploration companys’ drill holes in the northern part of the quadrangle. Although not shown, drill holes are generally located horizontally within 30 meters, and within 3 meters vertically. The locations and identity of drill holes are not shown because they are company classified information. The database was created by delineating the boundaries from scale-stable overlays on a USGS 7.5-minute topographic map at 1:24000 scale.
