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.
