Existing information indicates that the Madison aquifer would be reached at a drilling depth of about 2,500 feet; drilling should extend through the upper 300 feet of the aqu i fer. The Madi son aqui fer at the test site should have a potentiometric head about 150 feet above the land surface. Based on the specific capacity measured at Cowley's Madison No. 1 well about 8 miles southeast of the proposed Frannie-Deaver wellsite and the drawdown available at the proposed well-site, the proposed well would flow at a rate of about 300 gallons per minute. Water quality data for Madison waters in the area suggest that the water from the proposed well would contain less than 500 milligrams per liter (mg/l) total dissolved solids and less than 5 pico Curies per liter (p Ci/l) Radium. The well should be drilled to the top of the Madison aquifer with a 10 3/4-;nch drill bit, and cased with 8 SIB-inch 0.0. casing which would be cemented in place. The well should then be drilled about 300 feet into the Madison aquifer with a 6 3/4-inch drill bit. No well screen would be required. This recoll111ended construction would facilitate installation of a large variety of pumps, should one be required in the future, and would also allow entry of most workover tools should the well require work in the future. 1 r-R...;.• ...;.2~~E·rlR;.;.,;;.2;..;;,6..;,;E.,;.... _______.....:R.:.:., • .:.;26::...!::.,;E'T' !!.:R.~2:.!..7.!:,E.:..... ____ L..!..S.

Also discussed are the criteria used to select a site on which to drill a test hole to explore the possibility of obtaining a new water supply for the towns. Present Water Supplies The Town of Franni-e presently obta ins its muni ci pa 1 water supply from a 4,495-foot deep well drilled in 1955 and completed in the upper Madison Formation. The water from this well contains concentrations of Radium-226 that are about nine times the drinking water standard of 5 p CilL established by the United States Environmental Protection Agency (EPA, 1976). Recent analyses have also shown that the total dissolved solids content of the water is 1170 milligrams per liter (mg/L), which exceeds the EPA drinking water quality secondary standard of 500 mg/L. Because of the potential health risks attributed to high concentrations of Radium-226 in the Frannie municipal water supply, EPA has urged the Town to pursue options for solving that problem. The Town of Deaver presently obtains its municipal water supply from Deaver Reservoir, which is fed from the Shoshone River through the Garland canal and the Frannie canal, a major lateral of the Garland 5 cana 1 • Deaver trea ts the water from the reservoi r and pi pes it by gravity two to three miles to town. Remedial Actions Western Water Consultants, Inc. was hired by the Town of Frannie to investigate possible solutions to their water-quality problem. In April 1984 the existing well was reamed to remove incrustation inside the casing and was geophysically logged with natural garrma, temperature, ca 1i per, cement bond, and co 11 ar 1ocator tool s. The purpose was to gather detailed well-completion information, evaluate the integrity of the casing and of the cementation of the annulus, and identify zones of anomalously high radioactivity in order to determine the source of the Radium-226. The logs revealed that the casing is corroded and contains holes, and the cement bond between the casing and the well bore is very poor. The combination of these conditions may allow water from formations above the Madison aquifer to enter the well, and it is possible that the Radi um-226 may be enteri ng the we 11 from one of those water-beari ng units. It is also possible, however, that the upper Madison aquifer may be the source of the Radium-226. An attempt was made in August 1984 to isolate and sample water from the Madison aquifer by conducting a packer test on the Frannie well. It was planned to lower a packer on a string of tubing down into the uncased part of the well in the Madison aquifer and inflate the packer to allow only water from the Madison aquifer below the packer to flow up 6 through the tubi ng and to the surface. Water from the i nterva 1 above the packer, which would have included the upper 20 feet of the Madison and the cased part of the well, was to be allowed to flow to the surface between the tubing and the casing. The test would have provided two separate water samples; one from the part of the Madison aquifer below the packer, and another from the uppermost Madison plus any water that might have entered the well through the corroded casing. Both samples were to be analyzed for water quality, and the test would have shown whether the Madi son aqui fer i tse 1f was the source of the Radi um-226. The tes t fa i 1ed, however, because the 1a rge flow through the sma 11 annular space between the packer tool and the well casing prevented the packer tool from being lowered through the casing.

    Proceedings of the Seventh International Conference on Creationism. Pittsburgh, PA: Creation Science Fellowship SOUTH FORK AND HEART MOUNTAIN FAULTS: EXAMPLES OF CATASTROPHIC, GRAVITY-DRIVEN “OVERTHRUSTS,” NORTHWEST WYOMING, USA Timothy L. Clarey, PhD, MS, MS, BS, 2878 Oaklawn Park, Saginaw, MI, 48603, KEYWORDS: break-away fault, denudation, detachment, gravity slide, gypsum dehydration, overthrust ABSTRACT Overthrust faults have been a source of debate and discussion in creation literature for many years. Their interpretation demands a better explanation in a Flood context. Two fault systems are examined as analogies for an “overthrust” model. The South Fork Fault System (SFFS) and the Heart Mountain Fault System (HMFS) exhibit folding and faulting consistent with thin- skinned overthrust systems. Both systems moved catastrophically under the influence of gravity. The South Fork Fault system (SFFS, southwest of Cody, Wyoming, exhibits tear faults, tight folds, a triangle zone, and flat-ramp geometries along the leading edge of the system. Transport was southeast, down a gentle slope during early to middle Eocene time (Late Flood), approximately coeval with the Heart Mountain Fault system (HMFS). The SFFS detaches in lower Jurassic strata, rich in gypsum-anhydrite, overlain by about 1250 m of Jurassic through Tertiary sedimentary and volcanic rocks. Movement between 5 km and 10 km to the southeast spread the allochthonous mass over an area exceeding 1400 km2. A break-away fault and an area of tectonic denudation mark the upper northwest part of the system. The exposed denuded surface was buried by additional Eocene-age volcanic rocks soon after slip. Catastrophic rear- loading during emplacement of HMFS may have initiated subsequent movement on the SFFS, with dehydration processes trapping water in a near frictionless anhydrite-water slurry.

Box 7458, Fort Smith, MT 59035 3P.O. Box 821, Cody, WY 82414 ____________________ ABSTRACT - Paleontological resources occur throughout the Paleozoic and Mesozoic formations exposed in Bighorn Canyon National Recreation Area. Isolated research on specific geologic units within Bighorn Canyon has yielded data on a wide diversity of fossil forms. A comprehensive paleonotological survey has not been previously undertaken at Bighorn Canyon. Preliminary paleontologic resource data is presented in this report as an effort to establish baseline data. ____________________ INTRODUCTION ighorn Canyon National Recreation Area (BICA) consists of approximately 120,000 acres within the Bighorn Mountains of north-central Wyoming and south-central Montana B (Figure 1). The northwestern trending Bighorn Mountains consist of over 9,000 feet of sedimentary rock. The predominantly marine and near shore sedimentary units range from the Cambrian through the Lower Cretaceous. Many of these formations are extremely fossiliferous. The Bighorn Mountains were uplifted during the Laramide Orogeny beginning approximately 70 million years ago. Large volumes of sediments, rich in early Tertiary paleontological resources, were deposited in the adjoining basins. This report provides a preliminary assessment of paleontological resources identified at Bighorn Canyon National Recreation Area. STRATIGRAPHY The stratigraphic record at Bighorn Canyon National Recreation Area extends from the Cambrian through the Cretaceous (Figure 2). The only time period during this interval that is not represented is the Silurian.

PEPPE*, KIRK R. JOHNSON**, and DAVID A. D. EVANS*** ABSTRACT. We analyzed paleomagnetic samples and documented the stratigraphy from two sections near Miles City, Montana to determine the geomagnetic polarity stratigraphy and to constrain the age and duration of the Lebo and Tongue River Members of the Fort Union Formation in the northeastern Powder River Basin. The resulting polarity sequence can be correlated to subchrons C29n–C26r of the geomag- netic polarity time scale. By interpolating measured sediment accumulation rates from the base of C28r to the top of C27n, and then extrapolating to the top of the Tongue River Member and the bottom of the Lebo Member, we developed two age models to estimate the durations of the Lebo and Tongue River Members. Based on the first model, which uses different sedimentation rates for the Lebo and Tongue River Members, we estimate the duration of deposition of the Lebo to be between 1.30 and 1.74 million years and of the Tongue River to be between 1.42 and 1.61 million years. Using the second model, which uses the same sedimentation rate for the Lebo and Tongue River Members, we estimate the duration of deposition of the Lebo to be between 1.33 and 1.76 million years and of the Tongue River to be between 1.00 and 1.25 million years.

  • Bighorn Basin Province (034)
    BIGHORN BASIN PROVINCE (034) By James E. Fox and Gordon L. Dolton INTRODUCTION The Bighorn Basin is an asymmetric heart-shaped intermontane basin of the Rocky Mountain foreland, located in north-central Wyoming and south-central Montana. Province boundaries are defined by fault-bounded Laramide uplifts that surround it. These include the Owl Creeks to the south, Absaroka Volcanic Plateau and Beartooths to the west, Big Horns to the east, and the Nye-Bowler Lineament to the north in Montana. The province is about 175 miles long and 100 miles wide encompassing an area of about 13,200 sq mi. Approximately 1.8 BBO and 2.7 TCFG have been discovered (as of year-end 1990) since the first fields, Garland and Greybull, were discovered in 1906 and 1907, respectively. The vast majority of production has been from basin margin anticlinal structures such as Oregon Basin (475 MMBO, and 206 BCFG), Elk Basin (557 MMBO, and 368 BCFG), Hamilton Dome (261 MMBO), Grass Creek (212 MMBO) and Garland (200 MMBO and 142 BCFG). The largest stratigraphically trapped field is Cottonwood Creek (discovered in 1953) with 59 MMBO and 42 BCFG from the Phosphoria Formation. Plays in this basin result from both structural and stratigraphic traps and occur in primarily Permian and Cretaceous source rock and reservoir systems. Plays individually assessed or considered are treated in the following discussion. Conventional plays include Basin Margin Subthrust Play (3401), Basin Margin Anticline Play (3402), Deep Basin Structure Play (3403), Sub-Absaroka Play (3405), Phosphoria Stratigraphic Play (3406), Tensleep Paleotopography Play (3407), Greybull-Cloverly-Muddy Sandstone Stratigraphic Play (3408), Bighorn-Darby Wedge-Edge Pinchout Play (3410), Flathead-Lander and Equivalent Sandstone Stratigraphic Play (3411), Madison Limestone Stratigraphic Play (3412), Darwin-Amsden Sandstone Stratigraphic Play (3413), Triassic-Jurassic Stratigraphic Play (3414), Cody and Frontier Stratigraphic Play (3416), and Shallow Tertiary-Upper Cretaceous Stratigraphic Play (3417).
