Many of the basin valleys of western Nevada were inundated by Lake Lahontan during the Pleistocene. Adams, Wesnousky and Bills (1999) evaluated the rebound of the earth's crust when the weight of the water was removed as the lakes dessicated. One of the effects noted was the diversion of water from one basin to another. The Truckee is example of a river that may have been diverted to a different subbasin because of the effects of isostatic rebound. As the Truckee River exits its deeply incised bedrock canyon between the Pah Rah and Virginia Ranges, it takes an abrupt 90° turn to the northwest and terminates at Pyramid Lake. In the vicinity of Fernley, Nevada, the river is incised about 30 m into a package of surficial deposits that include the outcrops of the Wadsworth Amphitheater. Much of the incision may have occurred after the lake dessicated, which indicates that the Truckee River was lowered onto a relatively flat surface at about 1265-1270 m. What appears to be an abandoned river channel continues east from the vicinity of Fernley into the Fernley Sink. Others first noted this channel, but interpreted it to be pre-Lahontan in age. During the initial lowering of the Truckee River onto this surface the river may have occupied this channel, but the sense of uplift would have the effect of lessening its gradient. Continued rebound may have had the effect of diverting the river to the northwest, parallel to rebound contours, where it became incised into its present channel as base level continued to lower.

It's a bit desolate, and as you can see, the water is green from algae. Since I am pretty ignorant about the Humboldt River, I didn't know that its flow was lower here than farther east near Elko.

Although the tectonic evolution of southwestern North America (present-day) United States) is generally thought to include only two Paleozoic orogenies, the latest Devonian-early Mississippian Antler orogeny and the Late Permiam-earliest Triassic Sonoma orogeny, many workers have shown that there is considerable evidence for deformation at other times in the late Paleozoic.

Trexler, et al (2004) studied the excellently exposed unconformities in Carlin Canyon and other related locations such as Beaver Peak, Coal Mine Canyon, Grindstone Mountain, and the Goose Creek Mountains. They found that late Paleozoic deformation in the Great Basin is much more widespread and important than has been recognized. The contractional deformation occurred repeatedly between the times generally accepted for the Antler and Sonoma orogenies.

| Great Salt Lake State ParkOnce a part of Pleistocene Lake Bonneville, the Great Salt Lake occupies the largest northern basin. The Bear River dominates the hydrologic budget of the Great Salt Lake.The most recent major transgression and regression of Lake Bonneville spanned ~ 14C 30-12 Ka. About 14C 30 Ka Lake Bonneville began to rise from levels close to that of the modern Great Salt Lake. During this rise the lake oscillated at ~ 22-20 14C Ka, producing the Stansbury shoreline complex between 1347 and 1378 m. Following formation of the Stansbury shorelines, Lake Bonneville rose to its highest level of 1552 m by ~ 15.5 14C Ka (the Bonneville stage). At this elevation the lake overflowed intermittently for ~500-100 years near Zenda, Idaho into the Snake River basin, until catastrphic failure of the alluvial threshold dropped the lake level by ~100 m during the Bonneville flood at ~14.5 14C Ka. Immediately following the Bonneville flood, the lake level stabilized at 1450 m by the overflow at Red Rock Pass bedrock threshold, and the Provo shoreline formed. The lake regressed rapidly from the Provo shoreline sometime between 14 and 12 14C Ka, possibly to levels lower than the modern GSL. At the lake level receded past 1390 m, it separated into two basins forming Lake Gunnison in the southern basin. Lake Gunnison apparently continued to overflow along the Old River Bed into the northern basin until ~ 10 14C Ka. The lake remnant occupying the northern basin transgresses to the Gilbert shoreline (~1300 m) ~ 10.3 14C Ka, before dropping to levels <1287 m throughout the Holocene (Oviatt et al., 2001, Hart et al., 2004). | Locations: Salt Lake City.
