Just as I started up, right where the field starts sloping upward, under a big oak tree I spotted something white that looked suspiciously like bones. I always check those out. As I got closer, I could see it was a skull and initially I thought it was a horse. But as I kept looking, it was too small to be a horse, and then I saw: tusks! How appropriate for Pig Hill. I finished my walk up and back, then scouted around the area to see if I could find anything else of the skeleton - no. I carried it home - four pieces, top, jaw and the two tusks which had fallen out. I stuck it in a bucket of dilute bleach and found an old scrubber and washed it off nicely.
I didn't have time during the week to do any photography, but come yesterday morning as soon as I had some decent natural light coming in, set to work.
