You may wonder what this is and so do I. On our drive out in the "hills" yesterday, we came across several such substance on the graveled roads we traversed. When we saw our first of these substances, we didn't recognize them as animal dung. This "pile" is about 2 inches in diameter, and an inch and one half high. It is made up of 3-4 circles with the top one not much over an inch in diameter. Where there was one clump like this, there were 3-4 smaller pieces. Oddly, we must have seen 8-10 such clusters over a distance of 6--8 miles. All of the "deposits" appeared to be 2-4 days old. During the past few years, Farrel hogs have been identified in the area. My best guess is that it's Feral Hog Dung. I would welcome any comments and corrections.
