Thread: I Found It Over There

Pardon my ignorance but how did you determine it to be 700' thick? I guess "thick" does not necessarily mean "deep?"

I don't know about this case but you can check the USGS reports which describe pretty much all the formations and General Geology of the U.S and it would be mentioned there.

Thanks I assumed that it was something more practical than a shovel and a long rope, but really had no idea how to find such information. If I find a good rock, I'll check out the USGS.

I got the thickness and age from geology books. Colorado has many cases of sedimentary formations that are stood on end so that the strata is more or less vertical, in which case you can walk or drive across the thickness. A few miles out into the plains, these same formations are horizontal and 10,000 feet underground.
