Good Gosh Hoyt! I'm guessing that's a real spike, but it's so odd looking that it almost seem photoshopped? I know it must not be or you wouldn't have posted it, but I have never in my life seen anything as strange as that dude!
Unbelievable.
A short blocky nose, thick head and jaw structure, and grey around the muzzle and face are all good indicators of an older deer. The short blocky snout is a dead give away of a mature buck, only examination of the teeth will reveal his true age.
