Charles D. Walcott (1850-1927) records his observations of the Grand Canyon's northern side in 1879 while employed by the U.S. Geological Survey. Listed by date, his entries contain detailed descriptions of geographic sections, stone types, color, texture, and fossils found. This field book also includes notes made in Arizona after Walcott's death by Charles Elmer Resser, Alexander Stoyanow, and Edwin D. McKee in 1930. Notes from 1930 describe sites in Arizona at Music Mountain near Peach Springs, Del Rio, Algae in Naukoweap, Kaibab Trail, and Naukoweap Creek.

In 1879, geological assistant Charles D. Walcott became the 20th employee of the newly formed U.S. Geological Survey. Less than a year after Congress formed the USGS, Walcott was part of an expedition into Kanab Canyon en route to the Colorado River. While with the USGS, Walcott focused his efforts on biostratigraphy dating sedimentary rock bands by studying the fossils found in them. Specializing in invertebrate paleobiology, Walcott's work went on to transform our understanding of North American biology during the Cambrian era. Walcott served as both scientist and administrator later in his career, first as director of the USGS and later as the fourth Secretary of the Smithsonian Institution.
