The waters of the ancient lake have contracted to the area of the present Great Salt Lake. The drainage basin of the lake covers an area of about 21,500 square miles. Map of Lake Bonneville, showing the outline of the Bonneville shoreline, the highest level of the lake. Breach in the SPTC causeway, near Lakeside, looking northeast.
Several specialized programs comprise the UGS: Energy & Minerals, Geologic Hazards, Geologic Information & Outreach, Geologic Mapping, Groundwater & Wetlands, and Paleontology.  Lake Bonneville shorelines, and those of other paleolakes on Earth, are good analogs for shorelines on other planets, such as Mars.
At this elevation, the lake covers an area of 1,034,000 acres, and has a maximum depth of about 33 feet. Famous resort, Saltair, built in 1893 and destroyed by fire in 1971. Lake Bonneville, the most recent larger lake, formed the most striking of these beaches, deltas, spits, and wave-cut cliffs that are as high as a thousand feet above the present Great Salt Lake. Today’s Great Salt Lake is a large remnant of Lake Bonneville, and occupies the lowest depression in the Great Basin. The flow of water through the pass began a rapid downcutting process that caused a catastrophic flood. Great Salt Lake , Utah Lake et Sevier Lake sont les plus grands lacs post-Bonneville dans le bassin de Bonneville.

438 pp. Handy, 1969; 1966-1972 by J.A. La croûte terrestre s'est affaissée sous le poids de l'eau pendant que le lac existait, mais lorsque le lac s'est évaporé et que la charge en eau a été considérablement réduite, la croûte sous le bassin du lac a rebondi. Peterson, 1977. Lake area constraints on past hydroclimate in the western United States: Application to Pleistocene Lake Bonneville. Glad You Asked: How Do Geologists Know How Old a Rock Is? At that level the lake had risen to the lowest point on its basin rim and had begun to overflow into the Snake River drainage near Red Rock Pass in what is now southeastern Idaho.
The Western Interior Seaway preceded Lake Bonneville. Curry, G. Atwood, D. Mabey, 1983.
GK Gilbert a été l'un des plus grands géologues du XIXe siècle, et ses travaux monumentaux sur le lac Bonneville, publiés en 1890, ont préparé le terrain pour la recherche scientifique sur le paléolake qui se poursuit aujourd'hui.
Bien que le nom «White Marl» n'ait pas été utilisé par la communauté géologique dans un sens formel, le terme informel «white marl» (ou «Bonneville marl») est fréquemment utilisé. Developments in Earth Surface Processes 20. In his monograph on Lake Bonneville, G.K. Gilbert called the offshore deposits of Lake Bonneville the “White Marl.” Although the name “White Marl” has not been used by the geologic community in a formal sense, the informal term “white marl” (or “Bonneville marl”) is frequently employed. A ranch house on Antelope Island is said to be the state’s oldest Anglo-built structure on its original foundation and the longest continually inhabited building in Utah. Miller, W.E., 2002. Aerial extent, elevation, volume, and maximum depth of Great Salt Lake at historic high, average, and historic low-water levels. The massive Lake Bonneville flood is believed to have occurred between 14,000 and 15,000 years ago. Water is lost from the lake mostly through evaporation.
 Earth's crust subsided beneath the weight of the water while the lake existed, but when the lake evaporated and the water load was considerably reduced, the crust beneath the lake basin rebounded. Geology of North America K-3, Geological Society of America, p. 261-276; Oviatt, C.G., 2017. The extraction of common salt from the lake started in the mid-1800s and continues to be an important part of the State’s economy.
Three major shorelines were left by Lake Bonneville, and one by the Great Salt Lake. La plupart du temps, entre la fin du plus jeune des lacs profonds pré-Bonneville (le cycle du lac Little Valley, il y a environ 150000 ans) et la montée initiale du lac Bonneville il y a environ 30000 ans, le lac aurait ressemblé au Grand Sel moderne. Fixer la signification de chaque méta-donnée (multilingue). In about 1903, the railroad was constructed across the lake as a wooden-trestle structure.  Changes in lake level were the result of changes in water balance caused by climate change (a simplified version of the water-balance equation is inputs equal outputs plus-or-minus storage changes). Parry, 1971.

The 1,200-foot-tall smoke stack at the southern end of the lake is part of the Kennecott Copper Company’s copper ore-smelting operation. The lake stabilized and the Provo shoreline formed during the next 600 years. Natural Resources Map & Bookstore Isostatic rebound and palinspastic restoration of the Bonneville and Provo shorelines in the Bonneville basin, UT, NV, and ID.
and Wheat, M.M., 1979. . Lake Bonneville was the largest Late Pleistocene paleolake in the Great Basin of western North America.
Les publications précédentes considéraient le «rivage Gilbert» comme l'un des rives les plus importantes du bassin de Bonneville, mais cette interprétation a été révisée.
Approximately16,800 years ago, the lake rose to the elevation of Red Rock Pass and began to flow northward into the Snake River drainage.
Its relatively fresh water was derived from direct precipitation, rivers, streams, and water from melting glaciers.
Lorsque les intrants (c.-à-d. Précipitations; ruissellement dans les rivières) étaient supérieurs aux extrants (c.-à-d. Évaporation à la surface du lac; évapotranspiration dans le bassin), le niveau du lac montait et lorsque les extrants étaient supérieurs aux intrants, le niveau du lac diminuait. • Clay Mineralogy at the Brine-Sediment Interface in the South Arm of Great Salt Lake, Utah by L.L.
Doelling and others, 1991. O’Connor, J., 1993. Oolites are small spherical to elongated grains composed of concentric layers of calcium carbonate built up around a central core, much like a pearl. Flooding disrupted major highway and railroad traffic; inundated mineral-industry solar ponds, roads, beaches, farms, boating facilities and state/federal waterfowl management areas; and threatened water-treatment plants. For more than two years, starting in 1987, water was pumped from the north arm of the lake into the West Pond evaporation area in the west desert. Researchers estimated that water flowed at 15 …
What is the origin of the Great Salt Lake? Both Gunnison and Carrington Islands were unsuccessfully homesteaded for short periods of time. Since no humans witnessed this event we can only picture it in our minds. Elsevier. Why is the Great Salt Lake salty? Salts will by processed into potassium sulfate, a mineral fertilizer. Large quantities of bulk salt are shipped out-of-state for use in industry. Le lit d'inondation de Bonneville peut être identifié dans de nombreuses expositions de surface sous le rivage Provo et dans les carottes de sédiments.

In historical time (1847 to present), fluctuations of the lake level have varied over a range of 20 feet from a low of 4,191.35 feet in 1963 to a high of 4,211.85 feet in 1986-1987. • Shallow Ground Water and Related Hazards in Utah by S. Hecker and K.M. and Shroder, J.F., Jr., eds., Lake Bonneville: A scientific update.
La descente pendant l'inondation à travers les dépôts alluviaux du ruisseau Marsh et dans le sable, la boue et les débris de glissement de terrain du Néogène sous-jacent , a fait chuter le niveau du lac d'environ 130 mètres (425 pieds).
and Bills, B.G., 2016. These conditions persist despite two 15-foot-wide by 20-foot-deep open culverts that were built into the causeway to facilitate water and boat movement between the two arms, and despite a 300-foot-wide breach (opening) which was cut through the causeway near Lakeside in 1984 as a flood-control measure. A cross, carved into a rock near the summit of Fremont Island, reportedly by Carson, can still be seen today.
Late Pleistocene mountain glaciation in the Lake Bonneville basin.
Christenson, 1988. Un bref épisode de niveaux de lac légèrement plus élevés pendant le cycle du lac Cutler Dam s'est produit il y a environ 60 000 ans; à cette époque, un lac de taille moyenne s'élevait au-dessus du niveau du Grand Lac Salé, mais pas aussi haut que le lac Bonneville.

Who discovered Great Salt Lake? Also imagine that same ice-age lake releasing a surge of floodwater whose volume was six times the flood flow of the Mississippi River. • Mineral Occurrences in the Emergency Withdrawal Area and Adjacent Lands in the Great Salt Lake Desert by J.W. À ce niveau, le lac avait atteint le point le plus bas du bord de son bassin et avait commencé à déborder dans le drainage de la rivière Snake près de Red Rock Pass dans ce qui est maintenant le sud-est de l'Idaho.
