Zeolites were first found in the quarry in the spring of 1994. The quarry is at the intersection of 200/237 roads on Weyerhaeuser Mount Saint Helens tree farm. It is currently closed to motorized access. The quarry was established to provide material for logging roads. The quarry exposes three volcanic flows. Two are a black vesicular Eocene basalt of low potassium tholeiitic composition similar to mid-ocean ridge basalt. The lowest flow is a light green volcanic ash with areas of irregular cavities and veinlets.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

2.588 - 23.03 Ma

ID: 3186305
Cenozoic volcanic rocks

Age: Neogene (2.588 - 23.03 Ma)

Stratigraphic Name: Columbia River Basalt

Comments: Columbia Plateau

Lithology: Flood basalt(s); mafic volcanic rocks; basalt

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

Oligocene - Late Eocene
23.03 - 37.8 Ma

ID: 2764459
Upper Eocene volcanic rocks

Age: Paleogene (23.03 - 37.8 Ma)

Stratigraphic Name: Goble Volcanics Member; Pe Ell Volcanics Member; Hatchet Mountain Formation; Teanaway Formation

Description: Predominantly basalt flows and flow breccia; includes some pyroclastic and andesite rocks. Chiefly in western Washington.

Comments: Luedke, 1998, indicates that this unit has a large volume of andesite as compared to basalt. Walsh and others, 1987, indicate that this unit is almost entirely basaltic andesite flows of Oligocene to Eocene age with minor andesite, dacite, and basalt flows, and thin interbeds of shale, tuff, and volcanic sandstone. Hatchet Mountain formation consists of a base of basaltic conglomerate, sandstone, and water-laid tuff, underlying 2750 feet of basaltic and andesitic lava flows, flow breccia, pyroclastic,and tuffaceous sedimentary rocks. Increase in thickness to south and east as Cowlitz changes from marine to nonmarine (Roberts, 1958). Roberts, 1958, also suggests that Goble volcanic series includes Hatchet Mountain and parts of the Cowlitz and Toutle Formations (see WAOlv) as opposed to being contained within the Cowlitz formation. Phillips, 1987, maps the portion of the unit south of the Lewis River as basaltic-andesite and basalt flows with interbedded tuff and basaltic sandstone and conglomerate. North of the Lewis River are basaltic-andesite lava flows and flow breccia of the Goble Volcanics with interbedded sedimentary rocks. Small polygon in northern Ferry County tagged as WAEv1b in digital coverage is really WATas in original map.
