Summary:

Named for Hunter Creek. Type locality designated as exposures on Hunter Creek in SW/4 SW/4 NW/4 sec.26 T21S R39E, Malheur Co, OR. Exposed extensively in Monument Peak, Mahleur Gorge, and Harper Basin districts, usually as stone-striped slopes and domical hills. Consists of felty, microcrystalline, intergranular, intersertal basalt. Contains one to several flows. Thickness ranges from 3 to 400 ft; is 150 ft at type locality. Commonly rests on Dinner Creek Welded Ash-Flow Tuff (new); underlies Littlefield Rhyolite (new). Overlain indirectly by Butte Creek Volcanic Sandstone (new) which contains Barstovian fossils. Regional correlation chart shows age to be Miocene.
