Other Photos
All photos come from the USGS Photographic Library, Denver, Colorado, except where noted.
Latitude and Longitude measurements given in decimal minutes were taken with a Magellan NAV 5000 GPS unit; those given in degrees/minutes/seconds were taken from topographic quadrangles and have an error of about +/- 15 seconds.
Not much information is available on what each photographer was doing in the Rio Puerco. The following information is inferred from the figure captions available at the USGS photo archives in Denver.
- Schrader appears to have been most interested in the stratigraphy of
coal-bearing rocks in the Puerco basin, although he also made special note of
the volcanic necks in the area and "peneplaination."
- T.W. Stanton researched the biostratigraphy of the Mesozoic rocks in the Puerco
basin.
- W.T. Lee was in this area studying the stratigraphic relations and fossils of
the Mesozoic rocks that underly much of the Rio Puerco Basin. His research (with
some photographs) was published as United States Geological Survey Professional
Paper 101 in 1917.
- C.B. Hunt was part of a team working on "Fuels Project #5" in 1931-2.
- Leopold rephotographed many sites in the Southwest as research for the article
"Vegetation of Southwestern Watersheds in the Nineteenth Century" published in
Geographical Review, Vol. XLI in 1951.
