Hayward, R.K., Titus, T.N., Zimbelman, J., Hiza Redsteer, M., and Sunda, A.M., 2020, Grand Falls, Arizona: Dune Field Sand Transport 2013 - 2016: U.S. Geological 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 were collected from 10/28/2013 to 11/04/2016. 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, indurated interdune surfaces; all features commonly found on the Martian surface. We measured sediment flux using a Sensit saltation sensor and a set of three Big Spring Number Eight (BSNE) passive sediment samplers, at 20, 50, and 100 cm above ground level [...]
