550 m deep, below suburbs and lifelines. This geometry is not deep enough to produce gradients of west sub-basin. With constraints from water and geothermal wells, we found densities higher on average in the Reno basin than in other Nevada basins. Western sub-basin could be over 1 km deep. Eastern sub-basin not more than 0.6 km.
Airport is over a ridge.
Surface of west sub-basin is 100 m above floodplain, so deep basin was a surprise, since we had ignored the oil prospect. A casino drilled 1008 m injection well, hit andesite bedrock at 344 m. 1-d method underestimates depth near gradients. Regional basin densities too low for Pliocene diatomites and Quaternary alluvium. No density logs, one shallow acoustic log.
