Chris Bernhardt Posted December 20, 2010 Report Share Posted December 20, 2010 Either gravity driven water can errode rock in a reasonable amount of time or it can't. I'm on the can't side. There has to be other agents involved. Chris, Oregon Link to comment Share on other sites More sharing options...

John Kogel Posted December 20, 2010 Report Share Posted December 20, 2010 I have a question. Was the Grand Canyon carved by water erosion? Or is it a crack in the earth with a river running through it? If it was carved solely by the Colorado river running over the ground, where did all the sand go?

Chris Bernhardt Posted December 20, 2010 Report Share Posted December 20, 2010 It's a crack in the earth with a river running thru it and carbon-14 dating is a bunch of malarkey. Just my opinion. Chris, Oregon Link to comment Share on other sites More sharing options...
Marc Posted December 20, 2010 Report Share Posted December 20, 2010 I have a question. Was the Grand Canyon carved by water erosion? Or is it a crack in the earth with a river running through it? If it was carved solely by the Colorado river running over the ground, where did all the sand go? Wind and water erosion. It went where the water went. Jest guessin'. It got me thru college.[] Marc Link to comment Share on other sites More sharing options...
Mark P Posted December 20, 2010 Report Share Posted December 20, 2010 Erosion. I've read several books on the Canyon. The best book I read this year was "Down the Great Unknown: John Wesley Powell's 1869 Journey of Discovery and Tragedy Through the Grand Canyon". Not so much about the forming of the Canynon; however, it is discussed. John Powell and his men were absoulutly the luckest and bravest of men, what an amazing piece of history. An easy and entertaining read. Link to comment Share on other sites More sharing options...

Jim Baird Posted December 21, 2010 Report Share Posted December 21, 2010 "...where did all the sand go?..." There's a place in NE New Mexico called Great Sand Dunes where all the sand from a cpl of ranges/valleys, or whatever ended up. Very impressive.

nookandcranny Posted December 30, 2010 Report Share Posted December 30, 2010 I'm taking a global view here. Moss and other organisms like water, so whether it is wear from the excess discharge or the organisms basking in the abundant water, extensions to the ground or to a lower gutter will likely help to preserve the roof. I write this recommendation in my comments when I see such things. Link to comment Share on other sites More sharing options...

jimguy Posted January 24, 2011 Report Share Posted January 24, 2011 You have to love design flaws. In British Columbia, with all the rain we get. It feels like 50% off all new buildings, have serious flaws in their design. Link to comment Share on other sites More sharing options...
