Historical Documents

The Umatilla National Forest silviculture library has an archive of historical reference materials. With few exceptions, only items produced before 1950 are included in the history archive. 

The archive contains materials for the entire Blue Mountains, not just the Umatilla National Forest. This decision was made because national forest boundaries have evolved through time; much of the south end of the Umatilla National Forest was previously included in the Wallowa-Whitman or Malheur National Forests.

In 1995, the Umatilla National Forest decided to transcribe commonly requested reports so they could be offered in an electronic format. The table below lists the reports, and it provides a link to their abstract. Documents are organized by last name.

A historical reference document (Historical References About Vegetation Conditions: A Bibliography With Abstracts) is available that describes copies of the reports, maps, and photographs of the Blue Mountain National Forests listed below. This publication provides an overview of those National Archives resources.

Note: Many of the reports in this documents section were transcribed (retyped) from an original photocopy obtained from the National Archives. Transcriptions were done because some of the original Archive documents are difficult to read, either because the photocopy is poor or because the original typewritten material is uneven. The transcribed documents were checked for errors after the process was completed but unfortunately, some errors still exist in those files. As time and resources permit, we will attempt to scan the Archives copy and add the scanned original to the website too, so that both the original and transcribed versions will be available.
