AbstractsPotentially large supplies of ground water are available in the Sweetwater Rive basin from the Arikaree aquifer, which consists of the upper part of the White River, tb Arikaree, and the Ogallala Formations. A preliminary digital model was developed for tb Arikaree aquifer using a small amount of poorly distributed data, an estimated distri­ bution of recharge, and a conceptual model of the Arikaree aquifer flow system. Calibra­ tion of the model was based on reproduction of the potentiometric surface and the base flow of the Sweetwater River in November 1975. Calculated steady-state hydraulic heads were within 50 feet of the observed heads in about 98 percent of the nodes.

    Geological Survey Research 1961 Synopsis of Geologic and Hydrologic Results GEOLOGICAL SURVEY PROFESSIONAL PAPER 424-A Geological Survey Research 1961 THOMAS B. NOLAN, Director GEOLOGICAL SURVEY PROFESSIONAL PAPER 424 A synopsis ofgeologic and hydrologic results, accompanied by short papers in the geologic and hydrologic sciences. Published separately as chapters A, B, C, and D UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1961 FOEEWOED The Geological Survey is engaged in many different kinds of investigations in the fields of geology and hydrology. These investigations may be grouped into several broad, inter­ related categories as follows: (a) Economic geology, including engineering geology (b) Eegional geologic mapping, including detailed mapping and stratigraphic studies (c) Eesource and topical studies (d) Ground-water studies (e) Surface-water studies (f) Quality-of-water studies (g) Field and laboratory research on geologic and hydrologic processes and principles. The Geological Survey also carries on investigations in its fields of competence for other Fed­ eral agencies that do not have the required specialized staffs or scientific facilities. Nearly all the Geological Survey's activities yield new data and principles of value in the development or application of the geologic and hydrologic sciences. The purpose of this report, which consists of 4 chapters, is to present as promptly as possible findings that have come to the fore during the fiscal year 1961 the 12 months ending June 30, 1961. The present volume, chapter A, is a synopsis of the highlights of recent findings of scientific and economic interest. Some of these findings have been published or placed on open file during the year; some are presented in chapters B, C, and D ; still others have not been pub­ lished previously.

DESCRIPTION OF MAP UNITS ALZADA 30' x 60' QUADRANGLE Note: Thicknesses are given in feet because original field maps were on 7.5’ quadrangles with contour intervals in feet. To convert feet to meters (the contour interval unit on this map), multiply feet x 0.3048. Qal Alluvium (Holocene)—Light-gray to tan gravel, sand, silt, and clay deposited in stream and river channels and on flood plains. Clasts are subangular to well rounded. Deposits are poorly to well stratified and poorly to well sorted. Thickness generally less than 20 ft but as much as 30 ft. Qls Landslide deposit (Holocene and Pleistocene?)—Mass-wasting deposit of stable to unstable, unsorted mixtures of sediment. Deposit primarily as rotated or slumped blocks of bedrock and surficial sediment. Color and lithology reflect that of parent rock and transported surficial deposits.

The Cheyenne Table is part of the High Plains and is bounded by the valleys of the South Platte and Cache la Poudre rivers on the south and the valley of Horse Creek on the north. Two streams flow west to east on the table, one is Crow Creek that flows through Cheyenne and the other is Lodgepole Creek that eventually joins the South Platte at Julesburg. As one travels to the west, Crow Creek and Lodgepole Creek have cut progressively deeper into the Tertiary fill until they expose Cretaceous and older rocks next to the Laramie Mountains. However between Crow Creek and the Colorado line, the Tertiary rocks are not eroded and overlap onto the Proterozoic rocks of the core of the Laramie Mountains. This ramp of Tertiary rocks is called the Gangplank (Fig. 1). The Union Pacific Railroad was built on this feature in 1868, for on this surface there is a gradual rise of about 73 feet for every horizontal mile, or an incline of 0.8° (grade of 1.4% ).

The Pine Ridge Purpose and Scope The Arikaree aquifer is present throughout most of the study area as shown on sheet 1. Because the Arikaree Formation is structurally flat-lying Indian Reservation includes all of Shannon County and the part of Jackson County south of the White River. Extensive (dipping less than 1 degree) and regionally continuous, the configuration of the potentiometric surface is controlled locally by topography and major Indian trust lands are in Bennett County. For purposes of this map, the Pine Ridge Indian Reservation and all of Bennett 853 219 130 504 The purpose of this map is to present the potentiometric surface of the Arikaree aquifer for the Pine Ridge Indian streams (Rahn and Paul, 1975). The Arikaree aquifer is mostly under water-table conditions (unconfined) in the study area. The aquifer can be confined County are included in the study area (sheet 1). o o Reservation and Bennett County, South Dakota. The map provides a tool for estimating depth to water table for many where overlain by impermeable materials in the Ogallala Formation in the southern and southeastern parts of the study area. In the area underlain by the Ground water from wells and springs is the predominant source of public and domestic supply within the study 1,000 parts of the study area and also for evaluating ground-water flow directions and hydraulic gradients in the Arikaree Arikaree Formation, and including all of the younger units that overlie the Arikaree Formation, a single continuous water table was assumed by Ellis and area.
