Summary:

Named for Drip Spring SW/4 NE/4 sec.3 T22S R41E, Mahleur Co, OR. Measured type section designated as exposures in SE/4 sec.20 T20S R42E, Mahleur Co, OR. Composed of dark-yellowish-brown, yellowish-gray, and pale-yellowish-brown altered volcanic sandstones, peperites, feldspathic and arkose sandstones, siliceous diatomites, and carbonaceous volcanic shales that include both slope- and cliff-forming strata. Thickness is 260 ft at type; 700 ft along middle reach of Cottonwood Creek. Total may be 1500 ft. Overlies Littlefield Rhyolite (new); underlies Grassy Mountain Formation and Bully Creek Formation (new). Correlation chart shows Miocene age for unit.

Summary:

Shown on geologic map of Owyhee district, Malheur Co, OR, as Miocene and Miocene(?) age. Described as volcaniclastic and clastic fluviatile and lacustrine rocks similar in lithology and stratigraphic position to Deer Butte Formation. Peperites and basaltic intrusions within Drip Spring Formation, described as altered and zeolitized, are shown separately on map as Tertiary and Quaternary(?) age.
