Large pile of small stones (Pittsford)

I have a large amount of small stones that I sifted out of a massive pile of dirt. The stones are a mix of 1/4 inch to 2 inch diameter with most being 1/4 inch to 1 inch. The pile of stones is about 20 feet long, 3.5 to 5 feet wide and 8 to 12 inches tall. The stone is not washed stone--It has dirt on it. I have the pile on a tarp in my driveway. The stones are dry as I have been keeping them covered with a tarp. However, the overnight condensation can make them damp early in the day. Pittsford near Pittsford Plaza.
