Figure 3. Map of the Chimney basin and Snowstorm Mountains areas, showing the original known and inferred extents of the sedimentary basin, middle Miocene volcanic fields, dates of various sedimentary and volcanic units, and post-sedimentation normal faults and synforms. Areas that do not have an overlay color are underlain by pre-Miocene basement rocks (especially in the Santa Rosa and Hot Springs Ranges and Osgood Mountains), post-middle Miocene sedimentary cover (Paradise, Eden, and Kelly Creek Valleys), and post-sedimentation volcanic cover (Owhyee Plateau region). Some volcanic units along the northern Nevada rift and in the Santa Rosa–Calico volcanic fields were erupted after sedimentation ended, but they are included within the volcanic fields regardless of relative age. See Table 1 for geochronologic information. The modern digital elevation map is used as the base.
