Dave Twichell describing the geologic story of Lake Mead, as preserved in a vibracore, to middle-school students from the Las Vegas area.
Dave Twichell, a U.S. Geological Survey (USGS) geologist from the Woods Hole Field Center on sabbatical to the University of Nevada, Las Vegas (UNLV), participated in the dedication of a new vessel to be used for education and research on Lake Mead. One of the world's largest manmade reservoirs, Lake Mead lies behind Hoover Dam on the Colorado River east of Las Vegas. The lake is the site of several years of ongoing sediment studies by Dave and his collaborators.

In addition to the new vessel, named Forever Earth, a coring barge operated by UNLV and the National Park Service was on display at the dedication. Dave and Mark Rudin from UNLV were asked to explain the coring operations and show some of the cores to about 40 students, the press, and dignitaries as they toured the coring barge. The students were part of a middle-school chorus that sang at the dedication before touring the boats. Many of the students enthusiastically participated in the "hands-on" experience of touching the cores.

In addition to Dave, Ken Covay and Dan Bright of the USGS' Water Resources Discipline (WRD) were present to represent the USGS. Dan started his USGS career in the Coastal and Marine Geology team's geotechnical lab in Menlo Park, CA, and now works as a hydrologist in the WRD office in Las Vegas.
