Healey, D L; Miller, C H

The Timber Mountain area occurs within a volcanic province where Cenozoic volcanic rocks of unknown thickness are deposited. Analysis of gravity data indicates about 12,000 feet of these rocks are beneath Timber Mountain and in the moat. Gravity lows of small amplitude define the moat area, whereas gravity highs define the mountain, which is composed of extrusive rhyolitic and intrusive silicic complexes. Bouguer anomaly maps (densities of 2.67 and 2.20 g/cm/sup 3/) and residual maps (first-order and second-order surfaces) are presented. By correlating all four maps a better understanding of the subsurface structure is obtained. Three geologic cross sections are presented that define, in general, this structure. 9 figures, 3 tables.
