Rob will combine new fieldwork with LIDAR analysis and cross-cultural comparisons to shed light on what inspired the Chacoans to sculpt these monumental avenues. He is excited to be collaborating with leading experts on Chaco roads including Rich Friedman, John Stein, John Roney, and Fred Nials in planning and conducting fieldwork. Rob’s study will support further analysis of LIDAR data in search of Chaco roads, following the lead of the Solstice Project's 2010 LIDAR study of the Great North Road. This past summer, Rob and Rich Friedman visited 52 roads-related sites and outliers across New Mexico, Arizona, Utah, and Colorado with a permit from the Navajo Nation. They will continue roads fieldwork in the summer of 2020. The team will, for the first time, test optically-stimulated luminescence (OSL) dating, which measures the last time soil deposits were exposed to sunlight, to date Chaco road constructions.
