The Geologic Story of Colorado National Monument
Stanley William Lohman
1981, Bulletin 1508
From 1946 until about 1956 I carried out fieldwork intermittently on the geology and artesian water supply of the Grand Junction area, Colorado, the results of which have been published. The area mapped geologically contains about 332 square miles in the west-central part of Mesa County and includes all of...

Maps showing textural characteristics of benthic sediments in the Corpus Christi Bay estuarine system, south Texas
Gerald L. Shideler, Charles E. Stelting, Joseph H. McGowen
1981, Miscellaneous Field Studies Map 1275
Corpus Christi Bay is a heavily used estuary on the south Texas coast in the northwest Gulf of Mexico (fig. 1). The Bay is stressed by diverse activities which could substantially affect its ecosystem. Such activities include shipping, resource production (oil, gas, and construction aggregate), commercial and sport fishing, and...

Hydrologic data for North Creek, Trinity River basin, Texas, 1979
C.C. Kidwell
1981, Open-File Report 81-823
This report contains rainfall and runoff data collected during the 1979 water year for the 21.6-square mile area above the stream-gaging station North Creek near Jacksboro, Texas. A continuous water-stage recording gage was installed at one representative floodwater-retarding structure (site 28-A) on Oct. 5, 1972. The data are collected to...
Apparent water resistivity, porosity, and ground-water temperature of the Madison limestone and underlying rocks in parts of Montana, Nebraska, North Dakota, South Dakota, and Wyoming
L.M. MacCary
1981, Open-File Report 81-629
The need for large quantities of energy has increased interest in the Fort Union coal region of the Northern Great Plains. Extensive coal development would place a heavy demand on the region's limited streamflow. Some Paleozoic rocks that underlie the Fort Union coal region might supply, at least on a...
Hydrologic data of the lower Merrimack River basin, Massachusetts, from Concord River, Lowell, to Plum Island, Newburyport
David F. Delaney, Frederick B. Gay
1981, Open-File Report 81-1185
The lower Merrimack River basin study area drains approximately 180 square miles along the New Hampshire border in northeastern Massachusetts. This area includes parts of the Merrimack River basin within Massachusetts east of the Beaver Brook and Concord River basins, except for the Shawsheen River basin. Even though the Blackwater...

Lithostratigraphy of the Silurian rocks exposed on the west side of the Cincinnati Arch in Kentucky
Warren Lee Peterson
1981, Professional Paper 1151-C
This report discusses the Silurian rocks that crop out in Kentucky west of the axis of the Cincinnati arch. The Silurian System has a maximum thickness in this outcrop area of about 190 feet. It is in most places separated from the underlying Ordovician System by a minor erosional unconformity....
Gold placer and Quaternary stratigraphy of the Jabal Mokhyat area, southern Najd Province, Kingdom of Saudi Arabia
D. L. Schmidt, W.P. Puffett, W. L. Campbell, Z. H. Al-Koulak
1981, Open-File Report 82-414
An ancient gold placer at Jabal Mokhyat (lat 20?12.2'N., long 43?28'E.), about 90 km east of Qalat Bishah in the southern Najd Province, Kingdom of Saudi Arabia, was studied in 1973. Seven hundred and twenty-eight samples in 25 measured sections were collected along trenches and pits 2.5 m in depth...

Status of Regional Gravity Project, Kingdom of Saudi Arabia, as of 1 January, 1979
M. E. Gettings
1981, Open-File Report 81-165
Regional gravity data have now been obtained for approximately 33 percent of the area of the Arabian Shield, associated harrat areas, and the Red Sea coastal plain. Virtually no surveys have been done on the Phanerozoic platform around the edges of the shield, and although regional gravity coverage is available...
