Historic Oregon Topographic Maps, 1898-1993

Scope and Content Note

The Historic Oregon Topographic Maps consist of superceded or obsolete topographic maps published by the U.S. Geological Survey. The maps cover all of Oregon as well as small portions of the bordering states of California, Idaho, and Washington. The bulk of the collection consists of 1:24,000 (7.5 min) quadrangle maps that were issued predominantly in the 1950s through 1970s and 1:62,500 (15 min) quadrangle maps which date from 1906 to the early 1970s. The maps depict topography; vegetation cover; rivers and lakes; roads, railroads, and other transportation; political boundaries; and the boundaries of national forests and parks.

Of special note are topographic maps of the Willamette Valley and vicinity that were prepared in the 1900s-1910s; these depict the southern and central Willamette Valley from Springfield and Eugene to Albany. They are available online in the Oregon Maps Digital Collection.

The earliest maps in the collection are 1:125,000 (30 min) sheets published as early as 1898. The 1:125,000 maps include multiple editions for most sheets that depict changes and developments in Oregon locales from the 1900s through 1940s.

The U.S. Geological Survey provides online access to these maps through The National Map: Historical Topographic Map Collection.
