This is probably unique to my area, but it seems like when they build new neighborhoods, they grade everything by covering the original soil with a few feet of a different type of soil that gets trucked in. Once the house is built, they’ll do a final grade by adding even more different soil. I’m imagining the end result isn’t like what the USDA originally surveyed. I’ve got the mason jar test on my list to do after the catch cups.
