Glen Canyon Lecture Series Presents
“’Inside’ Ancient Deserts of the Western U.S: The Glen Canyon Page Sandstone Core” by Sandy Lindquist
Wednesday November 13, 2013, 7:00 p.m. (Mountain Standard Time) at Carl Hayden Visitor Center at Glen Canyon Dam.
In 1986, as an outgrowth of several years’ use of this area for an “applied-geology” field trip, more than 100 feet of Page Sandstone core was acquired from just northeast of the Glen Canyon dam near Page, Arizona. Local Page Sandstone knobs and mesas — and underlying Navajo Sandstone cliffs seen downriver from the dam — are the rock record of vast inland and coastal deserts nearly 200 million years old. This drilling project was undertaken jointly by geologists and petroleum engineers from the hydrocarbon exploration industry and from academia. The purpose was to better understand how fluid might flow within a defined volume of this type of rock, a volume which also could be mapped and visualized around its outcrop perimeter. Sandy Lindquist recently donated the original core and data acquired to the National Park Service at Glen Canyon National Recreation Area. Join Sandy as she describes this fascinating project and relates it to the regional geology of the area.
