I was hiking through my bush last week and saw this...or should I say I SMELLED this.
The pictures are in a sequence but it hardly matters.
I hesitated to post it as some people might not be accustomed to the raw side of nature.
The total length of the bones in picture # 1 is about 4 feet...hoof to hip so I would guess this was not a fully mature moose.
My 'recreation' of events is that at some time she got a piece of rope snagged around her leg/hoof and couldn't get it off.
Like most animals she would have panicked and tried to run away and most likely at some point got it further snagged in something...tree,branch...etc making things worse.
If that was what caused her demise it was is a question we'll never know but I have little doubt it 'contributed'.
I have provided a closeup shot I took of the rope and it seems obvious that it is NOT tied around her leg in any way so she wasn't a 'captive', just the bad luck to encounter a VERY stout piece of nylon climbing-type rope.
I say 'she' because I found most of the bones save any antlers and therefore concluded it was not a male.
The females do not grow antlers except I believe in the reindeer and elk group.
