Palouse Conservation Field Station
Palouse Conservation Field Station Photographs of Soil Conservation
1929-1965
2.75 Linear feet of shelf space
3 Boxes
The collection contains images showing the results of
environmental change on farm land especially due to erosion from 1930 into the
1960s. Though focused on that change in the Palouse region, the collection includes
images from other agricultural regions in the U.S. and some from other
countries.
Collection materials are inEnglish
Founded in 1930 as one of ten USDA-established erosion experiment stations, the
Palouse Conservation Field Station began as a joint venture between the United
States Department of Agriculture and the State College of Washington (later
Washington State University) and was located east of the campus in Pullman,
Washington on a 200+ acre farm that also includes offices, laboratories, a machine
shop, greenhouse, and other equipment buildings. Its name quickly changed from the
initial Pacific Northwest Soil Erosion and Moisture Conservation Experiment Station
to Pacific Northwest Soil Erosion Experiment Station Scientists to Pacific Northwest
Soil Conservation Experiment Station to Soil and Water Conservation Research Station
and many derivations thereof before becoming the Palouse Conservation Field Station
in 1961. Throughout its long tenure, the station sponsored the cooperative efforts
of USDA and Washington State University scientists to conduct agricultural
experiments, study the results of erosion on the Palouse landscape, and develop
better farming techniques.
The collection includes 1200 images, labeled negatives, nitrate negatives, prints,
unidentified images, and scrapbooks, showing the results of environmental change on
farm land especially due to erosion from 1930 into the 1960s. Though focused on that
change in the Palouse region, the collection includes images from other agricultural
regions in the U.S. and some from other countries. Additional images of interest
include some of Washington State College buildings and personnel and of the Snake
River canyon in the early 1930s.
Series 1: Identified images, 1930-1965. This series consists of more than 800 images,
most individually identified, with original captions and image numbers retained but
then re-numbered sequentially.
Series 2: Scrapbook pages, 1930 to 1960s. This series includes scrapbook pages with
mounted, captioned photographs as well as miscellaneous items including photographs
of agriculture-associated buildings, activities, and students and staff at
Washington State College. The scrapbook pages document activities at the Palouse
Station as well as other soil erosion experiment stations in the US.
Series 3: Unidentified images by topic, [1930s-1960s]. The images in this series are
identified broadly by topics and grouped accordingly in thirteen subseries with
original numbers retained. Image numbers are listed for each topic, but where
identifying information was available that image is itemized.
For images, the original detailed captions, when available, were retained as was the
filing sequence and original print and negative numbers, though the
photographs/negatives were re-numbered sequentially. In some cases, a print produced
from a negative received a separate original number, but, whenever possible, prints
were matched with the negative in this collection's sequential system. The
scrapbooks contain many mounted prints that may match unidentified prints/negatives.
The collection is arranged in three series, each of which occupies exactly one box.
This collection is open and available for research use.
Copyright restrictions may apply.
