Lake Bonneville Flood

Idaho Stae Journal ^ | July, 2003 | Jana Peterson

Dave Fortsch has simple advice for those trying to imagine what it would have been like to stand 15,000 years ago where modern-day Bannock County meets Oneida County.

"Hold your breath," the white-haired, wiry Idaho State University geology professor says cheerfully. "We're under 300 feet of water here."

For Fortsch, the signs of prehistoric Lake Bonneville - a large freshwater lake about the size of Lake Michigan that existed from about 32,000 to 14,000 years ago - and the flood that resulted when it overflowed at Red Rock Pass near Swan Lake are everywhere he looks. Fortsch stands in front of a part of the dam that failed 15,000 years ago, allowing Lake Bonneville to flood much of the Snake River plain.

"See the break in slope there," he says, pointing to where the slopes of the surrounding mountains suddenly get steeper. "Notice the older, more rounded topography above. Look up above the bench. Where you see the break above that, that's where the lake shore was."

Very interesting, thanks. (why did you excerpt the article?)

I imagine it's just selective perception on my part, but recently I keep seeing articles (here and elsewhere) about:

Black Sea Flood
Lake Aggasize Flood
Lake Bonneville Flood

There is just tons of scientific evidence that not too long ago (mere thousands of years) there was flooding which had profound changes for this world. Now, the only thing left to decide is whether it was just caused by glaciers, or if something else had a hand in it ...

why did you excerpt the article

It was my reason to post what I found to be interesting. I've been reading about the lake and found this article in a recent newspaper article. I really wanted to post the other websites.

A period when global warming ran amok. What filled the lake, and burst its boundaries, was the melting of the ice sheet that lay a few miles to the north.

And no SUV's or snowmobiles were involved. Not even many forest fires.

You are very observant! There *Have* been alot of flood postings lately. It's incredible that climates can change without man's help.

I'm personally indebited to Global Warming, because I don't think I could handle the Ice Age.

I don't need to go any further than my back yard in the Texas Hill Country to find signs. We have found hundreds of fossil sea shells up on top of a huge hill, there is no mistaking what they are. Hmmmm...wonder how those got there... : ) We also have found what we believe are dinosaur tracks in the creek bed.

Interesting, I was born near there.
