Abstract
Six exploratory wells were drilled into the cap rock underlying Salt Valley, Utah, for geologic, geophysical, and hydrologic data to augment information obtained from three previous test wells. Drilling of three other test holes was abandoned due to caving and loss of drilling tools, Before reaching the zone of saturation; the upper 100 meters of cap rock is unsaturated. Within the saturated part of the cap rock, hydraulic heads generally decrease with depth and to the northwest in this part of the valley.
Hydraulic conductivity of the cap rock, as determined from pumping tests, ranged from 9.3 X 10-5 to 2.06 X 10-1 meters per day; as a result, groundwater flow rates in the cap rock are low. Water ranges from a calcium bicarbonate sulfate type on the western edge of the valley to a calcium magnesium sodium bicarbonate, sulfate, chloride type near the center of the valley. Carbon-14 specific activity for cap-rock water yielded an uncorrected age of about 17,000 to 26,000 years before present near the western edge of the valley and about 41,000 years before present near the center of the valley.
