Geohydrologic analogies between the Jordan Valleys of Utah and the holy land

Abstract

The biblical Jordan River Valley , which extends from Lake Tiberias (the Sea of Galilee) to the Dead Sea, is decidedly similar to the Jordan River Valley of Utah , which joins Lake Utah and Great Salt Lake. Both Jordan Rivers drain relatively large fresh-water lakes and also are major sources of discharge into large salty lakes that have no outlets to the ocean.The two Jordan River valleys and the highlands and mountains that surround them, have many physiographic, geologic, and hydrologic similarities as well as some noteworthy differences. For example, an hypothesis for the formation of the Dead Sea- Jordan Valley rift is that the east Jordan block slid northward with respect to the west Jordan block. The amount of displacement is estimated to be about 65 miles and took place partly in Miocene and possible Pliocène and partly in Pleistocene time. Tectonc activity has also been a major factor in the formation of the Jordan valley of Utah , but the movement here probably was along large normal faults in late Tertiary and Quaternary time. The sediments underlying both Jordan River valleys were deposited in ancestral lacustrine and fluvial environments. Abundant supplies of ground water are found under both valleys , but probably larger supplies of better quality water can be obtained in Utah . Both valleys contain numerous small nonthermal and a few large thermal springs.
