What I could hear of the audio byte didn’t sound like what we heard. I would describe the sound starting like the HOO a howler monkey makes (if it were on steroids) then a guttural WAH or WAGH like a loud throat-clearing noise, then a YIYIYIYI like the sound Muslim women make at celebrations or funerals. Hu-wah-yiyiyiyi, and we heard it a few dozen times, coming from more throats than one. It sounded like they were three or four hundred yards off, but loud volume. After the several dozen calls they quit, and we got.
The weird thing is we were ridge hopping from one small valley to another, and as soon as we entered that particular valley we already had the hair standing up on our necks. No birds calling. Like something intuitive was telling both of us “you’re not welcome”, and not subtly, either.
Anyway, that’s the story. We had to go uphill to get out of that place, and we climbed out with the energy of Olympic gold medalists, and that’s the truth.
