  • THE GILBERT EPISODE in the GREAT SALT LAKE BASIN, UTAH by Charles G
    THE GILBERT EPISODE IN THE GREAT SALT LAKE BASIN, UTAH by Charles G. Oviatt MISCELLANEOUS PUBLICATION 14-3 UTAH GEOLOGICAL SURVEY a division of UTAH DEPARTMENT OF NATURAL RESOURCES 2014 THE GILBERT EPISODE IN THE GREAT SALT LAKE BASIN, UTAH by Charles G. Oviatt Department of Geology, Kansas State University ISBN 978-1-55791-893-2 Cover photo: View to the north of the southeast side of the Silver Island Mountains, northeast of Wendover, Utah; Lamus Peak is the high point on the skyline. The upper limit of the Gilbert-episode lake was at about the edge of the white sediment on the valley floor in the center of the photograph (the white sediment is the Bonneville marl and efflorescent salts). The Provo shoreline of Lake Bonneville is marked by the prominent tufa-cemented gravel rim on the flank of the mountains. The photo was taken from the Provo shoreline on a nearby hill, and tufa is visible on quartzite bedrock in the left foreground.
