THE FREMONT IRRIGATION PROJECT, CENTRAL UTAH
A Fremont irrigation system near Capitol Reef National Park in central Utah first shown to Noel Morss in 1928 is now known to be 4.5 miles long. A small ditch transported water (ca. 1.5 ft3 /second) from Pleasant Creek at 8,500' on Boulder Mountain to Jorgenson Flat, a 90 acre field at 7,100', and near large Fremont sites below. Fieldwork spanning 2010 – 2014 includes mapping the ditch route, excavations to expose profiles of subsurface ditches and linear sections of ditch, experimental archaeology to assess the costs of system construction and maintenance, and magnetometer survey to prospect for field modification at the terminus of the ditch system. Here we report progress in 2014 on chronology using optically stimulated luminescence dating and magnetometer imaging. We also evaluate traditional thinking about the Fremont in light of irrigation agriculture.
