The Earl F. Aldon Collection documents his scientific research with
the U.S. Forest Service, primarily in the south and southwest region of the Colorado
Plateau. Of particular interest is his research in the area of watershed and mines. The
strength of the collection lies in Aldon’s writings. These files contain the final product
as well as drafts, notes and correspondence with colleagues and co-authors. Also of great
interest are the research files. Although not as extensive as the Writings of Aldon series,
they contain raw data related to several mines in Four Corners area.

Biographical Note
Earl F. Aldon retired in 1994 as a supervisory research forester for the Rocky Mountain
Forest and Range Experiment Station and had been stationed at Albuquerque, New Mexico, for
31 years. He provided scientific support and expertise in the pinyon-juniper initiative on
region three of the Forest Service. He conducted watershed, range management and reclamation
research for the experiment station for forty-two years, after graduating from the
University of Michigan with a degree in forestry and an advanced degree in conservation. He
spent most of his professional career in the Southwest and wrote over one hundred and twenty
scientific publications.
Scope and Content
The Earl F. Aldon Collection documents his scientific research with the U.S. Forest
Service, primarily in the south and southwest region of the Colorado Plateau. Of particular
interest is his research in the area of watershed and mines. The strength of the collection
lies in Aldon’s writings. These files contain the final product as well as drafts, notes and
correspondence with colleagues and co-authors. Also of great interest are the research
files. Although not as extensive as the Writings of Aldon series, they contain raw data
related to several mines in Four Corners area.
Photograph collection consists of 35mm slides and loose photographs (some with negatives)
documenting his research and experiments in the areas of watershed, range management, soil
analysis, and mintes. Consists of two notebooks of 35mm slides, one box of prints (an
additional box of negatives), and one oversize box of larger photographs. Most images date
from the 1970s and 1980s.
