Thank you all. My dog thinks I am crazy b/c I always make her stand by the dumpster (bottom left of image) for a few minutes while I gaze at the hundreds of pounds of rock at my disposal (now covered in nemo snow). This is the second dumpster. The first one was longer and higher and full of rock.

I'll be boiling these for 5-10 minutes and then performing the vinegar test in the next few days.
