So this is the lava cap I mentioned. These rocks in the wheelbarrow came from a narrow 2x10 ft. by 6 inch deep pass of the rototiller (ugh). It's like digging up potatoes but a little less gratifying knowing I can't store these rocks for the winter. At least I'll never have to dig the craggly bits up again.
You can't imagine the sense of pride I have in this plot of land right now. My body aches in that way in which I know I've done an honest day's work on the acre.
