Here's a different subject that maybe you hunters and wilderness travelers can help answer for me.
The last week of Oct, I took a little solo camping trip up into the mountains of NM, just over the State line from Az., about 25 miles up the mountain from Reserve, NM. Camped next to Negrito Creek for those who know the area.
A couple of hours after sunset I was sleeping peacefully in my homemade 'Gypsy Wagon' (I was tired and hit the hay early). Which is a simple camper shell raised up with a two foot extension, covered with plywood and a thin skin of aluminum diamond plate.
It was a cold, three blanket, night even though the 'Wagon' is insulated. But I was sleeping comfortably when about 10 to 20 feet (guess) from the open window by my head 'something' started giving out a very LOUD cry/howl/mourn/growl!
Woke me right UP!
It started out (LOUD!) like a bugle kind of sound, as from an elk. Went into kind of a very mournful wail. And ended in a vicious kind of snarling growl. This was immediately followed by another shorter repetition of the same sound. Never heard it again. I have never heard an animal make any sound like this before.
Actually raised the hairs on the back of my neck.
I'm not Geronimo (or even a member of his tribe, Injun.) but I don't spook all that easily. People have asked me before "Aren't you scared to go camping alone?" Ive always said "Why, I'm the scariest thing up there."
Now I'm thinking I may be wrong about that!
I thought at first it sounded like a person with an elk bugle. Someone trying to play a joke on me (hilarious), but there were no other campers within miles of me that I saw coming in or the next day. Nobody was near me that I knew of.
It was elk season, and I had seen some hunters having their kill processed in Reserve but did not see any hunters on the mountain. By the way, the State of NM has apparently run out of money and does not maintain the road up the mountain any longer, it's in terrible shape. I thought (later)maybe it was a wounded elk that had been shot, or even an elk calf who had lost it's mother to hunters (might explain the mournful part of the wail).
I thought, Bear? No.
Coyote? No, don't think so.
Steer? Didn't see any coming up like I usually do. Don't know when the ranchers move their stock down the mountain. The 'vicious growl' part probably makes that unlikely.
Wolf? Possible, they have been reintroduced nearby, but the sound was unlike any wolf Ive heard.
Cougar? Ah, maybe.
Sasquatch? hmmmm?
I could not see much by shining my flashlight out the window, and no I did
NOT go outside to confront whatever it was!(I was in my underwear and it was cold, nothing more, really

I did reach over to make sure my 9mm was handy (wondered if 15 shots would be enough?) And I did quickly shut that open window by my head!
I laid there for a few minutes wishing I had put stronger latches and locks on those back doors. (can Bigfoot open doors?)
Then I drifted off to sleep figuring the noise of 'whatever-it-was' breaking in would surely wake me up.
In the morning, I saw no tracks of any of the afore mentioned suspects, and no blood from a wounded animal.
The ice chest on the ground behind the Gypsy Wagon was undisturbed. And it contained a recently cooked steak from the campfire of the evening before. Even though wrapped in tin foil, I'm thinking a hungry bear would have sniffed it out and ripped into that chest.
Coming down the mountain I saw no other people for miles. Saw no steer, saw no elk (which is unusual, but maybe hunters (or 'something') had scared them away from the road. Eventually made it home and searched Youtube for any hints of what might make a similar sound/cry. Even searched the great apes noises, nope not even close.
The closest thing I found on Youtube that made even a remotely similar sound, believe it or not, was some kind of wild rooster cry.
Any ideas what it might have been?
(Remember, this was before the election, so no it wasn't the mournful sound of a Liberal learning about the results of the election...
