Creation of the Matthes-Evans United States Geological Survey topographic map of the Grand Canyon was a herculean effort. It was the most impressive mapping activity to ever take place at the Grand Canyon, considering the surveying tools that were available at the time. Field work on the Matthes-Evans map began in 1902, but publication of the map did not occur until 1927. This was a 25 year effort, facing extremely challenging field conditions. This presentation will describe the surveying methods and tools used, and the field work required to prepare the Matthes-Evans Map. Extremely challenging terrain and climate made field work quite difficult. Matthes and others produced firsthand accounts that provide a historical record of the mapmaking effort and some of the trials and tribulations encountered by the surveyors. These sources, plus the author’s onsite visits to triangulation stations and benchmarks provide the basis for the story of the map’s creation.

In 1923 an expedition left Lees Ferry with the intent of making an unbroken level survey line 251 miles through Grand Canyon. This expedition was led by the Chief Topographic Engineer of the USGS, Claude Birdseye. His handpicked crew consisted of four boatman, a rodman and a cook, who navigated four boats over 74 day to complete this remarkable task. Birdseye and his men also ran survey lines up prominent side canyons and were charged with perhaps the most important aspect of the mission, locating potential dam sites. The level line that was produced from this expedition and the accurate maps of eight potential dam sites started a dialogue that would frame and potentially tame the wild Colorado River running through the West. These maps were ultimately used to aid in the creation of multiple dams and water diversion projects. Today researchers continue to utilize several maps, photographs and survey points almost 100 years after they were collected.
