Just yanking your chain a bit, Art. I'll defer to your more experienced judgement, but I did wonder if it isn't a wierd shovel instead, given it's position right next to the skull, as are shovel bases.
"Re-structuring" all the garage stuff- hauled pickup load to transfer site/"mall" yesterday and hung the 40-mile caribou rack from 3 years ago above one my son killed here on the Kenai awhile back. (Killey River Herd; re- introduced from Nelchina stock originally).
I'm not quite so proud of mine now....
Here's a better angle on the weird boy, also from behind Tustemena Lake/Killey Herd. His face was the most scarred up caribou face I've ever seen.
