Maybe too much info detail here.
I DO love that decomposed granite for lots of things, but has become difficult to find out this way. A pain. There is a bunch of pea gravel just sitting mounded up at an abandoned digging/crushing place across the way - would like to find a way to get a couple of loads of that.
The only "rounded" rock i was able to find up in NM was nature washed - they call it river rock - managed to get some mixed size in 20 yard loads - proved to be excellent for driveways. Came straight from a road building job site - from the river bottom to the excavator bucket to the belly dump, to our place. Never could find it sized.
Not so sure about the efficacy of that filter cloth - at least out this way. PO did that a bit here - years later there is black cloth working it way up through the original gravel driveway.
[[Lately, have used crushed Coronado Brown (1 inch) for covering new areas here. So far, so good, but summer rains will be the test.

thats what i mean about 1000 names, different rock , different color, as to decomposed granite, i just call it rotten rock and like it because its easy to dig out of the bank. Another is crushed shale ,nice to work with.
