Description
Geologic maps are to geologists what equations are to mathematicians; they symbolically and compactly encode many layers of hard-won scientific knowledge for those who know how to read them. The best ones also are beautiful. There have been great challenges and great progress in geologic mapping of Grand Canyon over the past 150 years. Dutton era (1886) maps represent major advances in cartography and geology. The Huntoon et al., (1996) 1:62,500 “Dragon Map” of Eastern Grand Canyon is the best-selling geologic map of all time; it was produced by offset printing and is now out of print. The Timmons and Karlstrom (2012) Geologic Map of Eastern Grand Canyon at 1:24,000 is the most detailed available for large areas; it has been digitized and is being converted to GIS files. The Billingsley’s USGS maps of the entire Grand Canyon region are available at 1:100,000 as GIS files online. Next challenges are to incorporate multiple scales in Google Earth-style zooming in interactive 3-D geologic portrayals. This requires higher detail boots-on-the-ground geologic mapping than is currently available in many areas as well as innovative ideas for 3-D visualizations. Imagery and visualization technologies are available such that this “Grand Challenge” is within reach.

Description
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.

Description
It is a truism that maps cannot exist without boundaries, whether those boundaries are the borders of the map itself or the geographic coordinates circumscribing the limits of the physical space being mapped. Grand Canyon National Park, like all national parks, has written and legislated descriptions that form the basis for mapping the evolving nature of the park. The year 1925 saw the first significant re-writing of the legal boundaries of Grand Canyon National Park since its legislative creation in 1919. This presentation will discuss the “sausage-making” involved in re-writing the borders of Grand Canyon National Park.
