The most intense flooding occurred over a period of several days–at most, several weeks , but over spilling at Red Rock Pass may have continued for as long as a year before the lake stabilized at 4,700 feet–the so-called “Provo shoreline”–and remained at that level for at least 600 years.
When did Lake Idaho drain?

How did Lake Bonneville turn into the Great Salt Lake?
Even though Lake Bonneville was fairly fresh, it contained salt that concentrated as its water evaporated. A small amount of dissolved salts, leached from the soil and rocks, is deposited in Great Salt Lake every year by rivers that flow into the lake.
How long was Lake Bonneville around?
Lake Bonneville, prehistoric lake, formed about 30,000 years ago (late in the Pleistocene Epoch), that at high water covered an estimated 20,000 square miles (52,000 square km), embracing much of what is now the western half of Utah and parts of Nevada and Idaho in the United States.

How did Lake Bonneville change Utah?
As the last ice age wound down 30,000 to 10,000 years ago, temperatures seesawed wildly. Lake Bonneville is a perfect place to study how wetness in the Great Basin changed as a result of those temperature swings: The lake’s water levels rose and fell by hundreds of feet during this time.

What is the last remnant of Lake Bonneville?
Remnant lakes of the original Lake Bonneville can still be seen in three places: Sevier Lake, Utah Lake , and the Great Salt Lake. These three lakes represent the deepest parts of the original Lake Bonneville and are endorheic basins from which the major egress for water is now evaporation.
What was the highest elevation of Lake Bonneville?
The elevation of the lake was about 5,090 feet at its highest (as measured near Red Rock Pass in southeastern Idaho), more than 1,000 feet deeper than present day Great Salt Lake (Currey and others, 1984). Simplified lake level elevations over the past 30,000 years.
How long ago was Utah underwater?

What was Utah like 10000 years ago?
The climate 10,000 years ago was much different. Utah’s temperatures were cooler and it might have rained more often . Paleoindians camped along the shores of lakes and streams, including the Great Salt Lake, which was much larger and not yet salty.
Why is the Salt Lake salty?
Why is the lake salty? Because the lake does not have an outlet, water flows into the lake and then evaporates, leaving dissolved minerals behind as residue . On average, 2.9 million acre-feet of water enters the lake each year from the Bear, Weber, and Jordan Rivers. The inflow carries about 2.2 million tons of salt.
Why can’t you swim in the Great Salt Lake?
Most simply forsake the lake in the summer when the brine flies are thickest. Year-round, though — and there are swimmers who take to the lake no matter how cold the air and the water — the salt is painfully corrosive on bare skin . “It’s almost like sandpaper rubbing against you,” Gridley explains.
