How to make sand.

Uh....some mountains are still high. Some others, like the Wichitas in southwestern Oklahoma, don't get above 2500 feet. All that's left is house-sized granite boulders that were the cores of Himalaya-scale mountains in the Silurean, and thousands of square miles of the Granite Wash formation down below the ground. The Granite Wash is made of cobbles, rocks, and sand-sized stuff that eroded off the mountains and washed out past Amarillo, Texas. Some of it is under four miles of newer sediment now.

How fast does the Wind/Bighorn flow every May during snowmelt? I think you'll find that sand in great abundance down along the Yellowstone, Missouri, and Mississippi Rivers and out around Venice, Louisiana, Buz. Just the big rocks are all that stays in the riverbed up in the mountains. And the Windriver Range looks "young" because, compared to the Wichitas or the Adirondaks, it is young. Like one-fifth to a tenth as old.

At that point in time, bach in the Hadean, when the crust of the Earth was just solidifying from a molten state and there was just a crust in the "upper layer of a pie" sort of sense. That's when.Edited by Adminnemooseus, : Fix quote box. Ending with [/i] doesn't do it.
