Adam M Hudson
I am an isotope geochemist focused on applying radiogenic and stable isotopes to understanding hydrologic systems in the present and geologic past. My main research goal is to understand what affects water availability in arid regions.
My research focuses on two parallel tracks: 1) Tracing water sources in modern surface and groundwater systems and 2) reconstructing landscape evolution through geologic mapping and isotope study of surficial deposits of lakes, rivers, soils, and desert springs and wetlands. I have done research in Tibet, the Andes, and the western United States. My current research is focused in the US Great Basin, Alaska, and the southern Rocky Mountains of Colorado and New Mexico.

Reduced population variance in strontium isotope values informs domesticated turkey use at Chaco Canyon, New Mexico, USA Reduced population variance in strontium isotope values informs domesticated turkey use at Chaco Canyon, New Mexico, USA
Traditionally strontium isotopes (87Sr/86Sr) have been used as a sourcing tool in numerous archaeological artifact classes. The research presented here demonstrates that 87Sr/86Srbioapatite ratios also can be used at a population level to investigate the presence of domesticated animals and methods of management. The proposed methodology combines ecology, isotope geochemistry, and...

Preliminary geologic map of the Big Costilla Peak area, Taos County, New Mexico, and Costilla County, Colorado Preliminary geologic map of the Big Costilla Peak area, Taos County, New Mexico, and Costilla County, Colorado
This map covers the Big Costilla Peak, New Mex.‒Colo. quadrangle and adjacent parts of three other 7.5 minute quadrangles: Amalia, New Mex.‒Colo., Latir Peak, New Mex., and Comanche Point, New Mex. The study area is in the southwesternmost part of that segment of the Sangre de Cristo Mountains known as the Culebra Range; the Taos Range segment lies to the southwest of Costilla Creek and...

Preliminary geologic map of the Vermejo Peak area, Colfax and Taos Counties, New Mexico and Las Animas and Costilla Counties, Colorado Preliminary geologic map of the Vermejo Peak area, Colfax and Taos Counties, New Mexico and Las Animas and Costilla Counties, Colorado
This geologic map covers four 7.5-minute quadrangles-The Wall, NM-CO (New Mexico-Colorado), Vermejo Park, NM-CO, Ash Mountain, NM, and Van Bremmer Park, NM. The study area straddles the boundary between the eastern flank of the Sangre de Cristo Mountains and the western margin of the Raton Basin, with about two-thirds of the map area in the basin. The Raton Basin is a foreland basin that...
