My plan is to drill and cleave off a 2" thick slab. Then saw that slab into 3/4" X 2" X 'whatever' (7" ish) pieces. I will have to saw from both sides to get through the 2" with the saw that I have.

Well, the time consuming part was started 70 million years ago.

Well if you get to thinking that it is too much remember that there is always rental tools in Denver. You may also have the possibility of getting some stuff cut for you at countertop or tombstone places, and likely for peanuts. It may take a little networking to get it figured out.

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.

Ooooo weeee that's a pretty rock!! I really really hope it works out!

This may or may not be a good idea but why don't we create a trend giving information on the type of rock(if known), general location on where it's found, and the type of edge it can put on a razor. If we put it all on a map than we could create a geological sharpening stone map for the people. In doing so you can find out which types of stones you won't to try and where you would have to go to get it.
