- 23 - <br />is water bearing or if there is a hydrologic connection between the <br />Slick Rods at the mine and the Slick Rock in the vicinity of the <br />spring. <br />The Limestone Member of the Hermosa Formation underlies the mine <br />at a depth of about 5,000 feet. Rocks of very low permeability make <br />up the majority of the intervening strata. In this area, the <br />limestones are in direct contact with the evaporites in the Paradox <br />Member of the Hermosa Formation. Regional ground water studies, <br />Hanshaw and Hill (1969) indicate that ground water in the Limestone <br />Member of the Hermosa Formation and underlying older Paleozoic rocks <br />are brines with considerable cross - formation flow. <br />In addition to the formations with moderate to high permeability, <br />other bedrock strata are present in the region with low hydraulic <br />conductivities and are potential aquifers when below the water table. <br />The potential low permeable aquifers are: <br />(1) Salt Wash Member of the Morrison Formation. <br />(2) Kayenta Formation. <br />(3) Wingate Sandstone. <br />The mine is located in the upper portion of the Salt Wash Member <br />of the Morrison Formation. The Salt Wash Member is made up of <br />alternating sandstone and mudstone lenses. Ground water has not been <br />encountered during mining operations to date. In addition to <br />examining the existing mine, the accessible workings of the abandoned <br />Paradox D claim which adjoins the JD-5 lease on the northwest were <br />also inspected and found to be dry. This mine was abandoned in the <br />-•-ate 1950's. <br />
