0 for 2 on this one. Cleared away a lot of leaves. Investigated sites of old diggings. Brought out the kid's metql detector and still failed. The -17C didn't help. There is a rock about a foot in diameter about 1m south of ground zero that is literally frozen onto the surface of the ground. I tried to leverage it off with various logs, dig around it with my trowel and various kicking attempts to no avail. My gut says the cap is under there (and I'm usually wrong), but I'll have to bring a crowbar or shovel out (that would look interesting) or wait till spring. I think it'll be the latter.
