Department of Natural Resources Geology a;,j Earth Resources Olympia, Washington 98504

Alluvium deposited by modern streams; includes beach deposits . north of La Push.

Drift deposited by the Juan de Fuca lobe of the cont'inental ice sheet. Mainly poorly sorted sand and gravel with local ablation and lodgement till.

Moraine formed by the Juan de Fuca lobe. Mainl y ablati on till.

Outwash terraces formed by the latest Juan de Fuca lobe melt­waters. Mainly stratified sand and gravel .

Juan .de Fuca lobe outwash terraces that are older than Qct3, but younger than Qct1• Mainly stratified sand and gravel with a discontinuous mantle of loess.

Juan de Fuca lobe outwash terraces that are older than Qct2. Mainly stratified sand and gravel with a mantle of loess.

Drift deposited by Olympic Mountain alpine giaciers. Ma i nly till and local sand and gravel.

Quinault Formation: Massive to well bedded siltstone and sandstone and conglomerate.

Hoh Rock Assemblage

Explanation

Massive to thin-bedded siltstone

Thin to medium bedded siltstone and sandstone of about equal amounts.

Massive to thick bedded grayw_acke sandstone.

Melange rocks of intensely sheared claystone and siltst one con­taining blocks of indurated siltstone, graywacke sandstone and altered volcanic rocks.

Explanation

Volcanic rocks, undifferentiated, including very large blocks within melange rocks.

Silts tone and sandstone undifferentiated.

Mapped lithologies of the Quinault Formation and Hoh Rock Assemblage are based on unpublished mappin.g by Weldon W. Rau, Department of Natural Resources, Division of Geology and Earth Resources, Olympia, Washington.

Subdivision of Quaternary units based on unptiblished mapping by A. Dan Horn, North Seattle Community College, Washington.
