Bedrock: Ogallala Group

Tertiary (Upper to Middle Miocene)

Caliche-cemented sandstone, algal limestone and shale, called by some geologists the Kimball Formation, but not considered a mappable unit by others. The heterogeneous sedimentary materials in the Ogallala Group were eroded from mountains farther west that had been elevated during the Laramide Orogeny. The sediments were deposited as a huge apron stretching eastward toward the Missouri River. Subsequent erosion separated the Ogallala from its source area in the Rockies, leaving a high plateau that gradually decreases in elevation toward the east. The Ogallala serves as an important aquifer throughout the Plains states and is recharged by precipitation and snowmelt in areas such as Panorama Point.

The Ogallala Formation is underlain by the White River Group, which contains a higher proportion of volcaniclastics, and is well exposed along Pine Bluffs, a long cliff that stretches parallel to the Nebraska-Wyoming border from three miles west of Panorama Point north to I-80 at the town of Pine Bluffs, Wyoming. Oil and gas are extracted from the still deeper Cretaceous sandstones and Permian limestones in Kimball County. The Permian rocks are at the base of the same sequence of rocks exposed at Texas’ highest point and also tapped for oil in New Mexico and west Texas.

Surficial Geology: Pleistocene glaciation did not extend into this area.

Soil Series: Canyon Complex: very shallow, grayish-brown, calcareous loamy soils developed under short grass prairie over weathered sandstone and limestone.
