Hayward, R.K., Titus, T.N., and Sunda, A.M., 2020, Grand Falls, Arizona: Dune Field Sand Transport 2017 - 2019: U.S. Geologic Survey data release,


As part of a NASA-funded study of sediment flux rates at a Mars analog site, we installed a suite of instruments in a small dune field near Grand Falls, Arizona. Data released in this report was collected from 02/07/2017 to 05/22/2019. The Grand Falls (GF) dune field is located on the Navajo Nation. It lies ~70 km NE of Flagstaff, AZ, 2 km east of Grand Falls, and just north of the Little Colorado River (LCR). The dune field consists of barchans, smaller dunes/ripples, and bare interdunes with indurated surfaces, all features commonly found on the Martian surface. We measured sediment flux using a Multi Layer Solid State Saltation Sensor (MLS4) and a set of three Big Spring Number Eight (BSNE) passive sediment samplers, at 20, 50, [...]
