Summary:

Named for exposures on Dinner Creek and at type section on Conroy Creek, 0.5 mi north of Lower Deacon Flat Reservoir, NW/4 SE/4 sec.30 T21S R39E, Malheur Co, OR. Crops out as prominent ledge in Monument Peak and Malheur Gorge districts. Consists of pale-brown to grayish-red rhyolitic welded ash-flow tuff. Where completely displayed has lower zone of no welding; zone of dense welding; upper zone of partial welding which includes lithophysal zone; perhaps upper zone of no welding. Thickness ranges from 20 to 200 ft. Overlies unnamed igneous complex in Monument Peak and Malheur Gorge districts. Underlies Hunter Creek Basalt (new). Overlain, indirectly by Butte Creek Volcanic Sandstone (new) which contains Barstovian fossils. Correlation chart shows Miocene age.
