A zone of lignite beds of Paleocene age in the Denver Formation (Upper Cretaceous and Paleocene) lies about 800-1,500 feet above the well-known and extensively mined coal beds of the Laramie Formation (Upper Cretaceous). The zone is a few hundred to as much as 500 feet thick. Where lignite beds...
Summary appraisals of the Nation's ground-water resources; Texas Gulf region
E. T. Baker Jr., James Ray Wall
1974, Open-File Report 74-331
Ground water in the Texas-Gulf Region is a large and important resource that can provide a more significant percentage of the total water supply of the region.

1974, Open-File Report 74-178
An assessment of gravel needs in Front Range Urban Corridor markets to 2000 A.D., based on forecast population increases and urbanization, indicates that adequate resources to meet anticipated needs are potentially available, if future land use does not preclude their extraction. Because of urban encroachment onto gravel-bearing lands, this basic...
