- JSchroeder, on 01/19/2008, -0/+3Data published in the peer-reviewed journal Science are extremely reliable. So when these researchers say "the streams studied by their geological predecessors were not “natural archetypes” but rather the artifacts of 18th- and 19th-century dam building and deforestation," I believe them.
- bincoder, on 01/19/2008, -0/+3I only get worried when the 'I know it all' types start talking about 'restoring' when they have no idea what it is they are 'restoring'.
- rollem, on 01/20/2008, -0/+2I imagine the effect of beavers was less than humans. It might be worth studying, however.

okay, not exactly what you wanted, but it is the most awsome example of a river turning into hundreds of dis-tributaries I could find. - rollem, on 01/20/2008, -0/+2Gee, I guess they shouldn't reexamine geology when you seem to already know the answers.

"Where all this water goes is a mystery", Aurel Schultz, 1897 - DrewInBalto, on 01/19/2008, -2/+4They don't mention beavers. A beaver dam should have the same effect as a millpond dam. Lame study.
- xxpor, on 01/19/2008, -0/+1how do you know?
- JSchroeder, on 01/19/2008, -0/+1I'd love to see examples on Google Maps. Anyone know of one?
- lucutus, on 01/19/2008, -1/+2http://maps.google.com/maps?q=grand+canyon&ie=UTF8 ...
- lucutus, on 01/19/2008, -0/+1I was thinking the same thing but then again a beaver dam made of wood and mud does not last as long as one that is man made of rock and earth. So simmilar but not to the same scale. Beavers also do some deforestation but again not to the same scale.
- SadMartigan, on 11/25/2008, -0/+1Hundreds, as in 200, yes; just not 500.
- lucutus, on 01/19/2008, -0/+1I thought everybody knew how water flowed. I think the narrow channel cut through theory still stands. I mean there is plenty of historical evidence of this. Take a look at any gorge or canyon. http://maps.google.com/maps?q=grand+canyon&ie=UTF8 ...
- cryonix, on 01/19/2008, -1/+2im i the only one who loved the space needle falling down ad more than the article?
- SadMartigan, on 11/25/2008, -0/+1Beavers do continue to repair and modify their dams, from generation to generation, and they can last for a very long time.
- cosmikat, on 01/19/2008, -0/+1Just yesterday, I was reading a genealogical transcript orated by a settler from the 1890's in Cloud Chief, Oklahoma, who reported having to haul water from the river to the settlement (http://www.rootsweb.com/~okgenweb/pioneer/ohs/aber ... Out of curiosity, I looked up the area on Google Earth. Cloud Chief, Oklahoma is now just a four-cornered intersection in the middle of nowhere, with what appears to be an old, dried-up stream with its oxbows and meandering serpentine features just south of where town used to be. I DID notice, though, quite a few small dams forming what may be stock tanks and pond-sized reservoirs. I assumed that local ranchers were attempting to preserve whatever water they could by using dams in a disappearing stream, but after reading this article, I am now wondering if the dams were the CAUSE of the river displaying all the signs of an "old" stream that is drying up.
- rollem, on 01/20/2008, -0/+1Even by 1491, the Western hemisphere had been dramatically altered by human presence. Restoring an area to the way it was in 1950, 1850, 1491, or 10,000 BCE is an interesting debate.
- SadMartigan, on 11/25/2008, -0/+1Excellent observation. I believe the purpose of the study was to refine our understanding of the natural tendencies and physics, but this time to take into account what previous studies had not; the influence of mankind. I also (as you appear to) wonder if they recognized the effects of beaver dams, when they began to discount the old theory based on man-made interference.
- ezkash, on 04/04/2008, -0/+1I wish the waterflow in my apartment worked. http://broaty.info
- SimpleAlex, on 12/29/2008, -0/+0Very interesting googlemap examples.

http://makeupapplication.org/ - bestbuyout, on 12/13/2008, -0/+0I just saw the documentary on 'history channel' - how the earth was made..
they said that asteroids brought water to earth, what do you think?
http://www.coupon-promo-code.com/ - fantasticjon, on 01/19/2008, -2/+2Nice theory, but I go kayaking in a lot of Pennsylvania Creeks and Rivers and the old mill dams are still there. At least the bases of them are. The paths of the rivers and creeks have not changed that much in 100s of years. Its a natural formation.
- b1344, on 12/08/2008, -0/+0Those googlemap examples are pretty interesting..
I womnder if they can use it to find more water for the thirsty millions of Africa..

- lukak, on 01/19/2008, -4/+2wow...I'm really, really uninterested in this.
