Richard J Moscati
Rick Moscati currently works in the Geology, Geophysics, and Geochemistry (G3) Science Center conducting research in geochronology and isotope geochemistry.
Rick Moscati began his career in Chicago as a geologist for the USEPA in 1990. In 1991 he was hired by the USGS, Branch of Isotope Geology in Denver, and then transferred to the Yucca Mountain Project Branch (YMPB) where he conducted research from 1992 to 2010 in stable isotope and fluid inclusion studies on the history of secondary mineral deposition (largely calcite and silica) in soil and unsaturated-zone settings and as PI of the Isotope and Chemical Monitoring of Precipitation study. Since 2010 Rick has focused on geochemical studies involving radiogenic isotopes (U, Pb, Sr, and Nd) using TIMS techniques, trace element geochemistry, and in situ (SHRIMP and LA-ICP-MS) U-Pb analyses of minerals for geochronology studies. Among the many projects he was/is involved in, a few standout: zircon geochronology of the Proterozoic Colorado Province, the Afghanistan geochronology project, Angel Lake (Nevada), Chalk River (Ontario), the Mountain Pass REE deposit (California), and the U-Pb dating of cassiterite from many locations and geologic environments around the world including the Sullivan SedEx deposit (British Columbia), Cornwall (England), Abu Dabbab (Egypt), and Yazov (Russia). In 2018 Rick expanded his research and joined the 40Ar/39Ar geochronology lab where he assists in method development and providing a variety of USGS and outside projects with 40Ar/39Ar age data of volcanic rocks.

Argon Geochronology
This project supports the USGS argon geochronology laboratory in Denver. The USGS 40Ar/39Ar geochronology laboratory is a state-of-the-art research facility for determining absolute ages of minerals and rocks. The 40Ar/39Ar laboratory contributes critical geochronology to individual USGS research projects and to partners in academia and other Federal agencies. This laboratory develops methodology...

Don't be groover shy
The "groover" is river slang for the toilet. At every camp, the groover site is choosen to accommodate a scenic view as well as to provide its users with a modicum of privacy. At our Ledge Camp, it was easy to find groover users an incredible view, but the privacy factor was in short supply. If you're on a river trip, you can't be groover shy!

John Weisheit scouts Rapid 15 to the SCREE team
The SCREE team gathered around John Weisheit overlooking Rapid 15. John Weisheit is a river guide who has made over 400 trips through Cataract Canyon. He is describing to the SCREE team the line to take through the forthcoming sets of rapids.

Taken from the saddle, a panoramic view of the Bowknot Bend of the Green River. The Bowknot Bend is 7 river miles around. Erosion will eventually shorten the river course considerably.

Dellenbaugh Butte along Green River
At about Mile 102 you can see Dellenbaugh Butte, which is also known as The Anvil, or Inkwell Butte. Powell camped here July 14, 1869. The majority of the butte is composed of the Summerville Formation.
