Dry Creek Volcanics consist of airfall andesite breccias, minor mud-flow breccias and andesite flows with thin localized dense basalts. Field characteristics include dark pumiceous tuffs with numerous breadcrust and cow dung bombs. Dry Creek volcano became active in Oligocene prior to major uplift of Warner Range.
