For the past 3 years, around the same time every year, I visit a remote location in Washington state for solo camping and hiking. It's several hours away, and with my work schedule I don't get to visit very often. I go at a time when the campgrounds are all closed and no other humans are around. I have a pretty built-up rig that can get me places most others can't during the off-season. I don't want to reveal the location for obvious reasons. Every night that I have camped in this particular spot, I have clearly heard booming vocalizations (screams and howls) that have both terrified and intrigued me. As a skeptical person, I'm not going to jump to conclusions and say "It's Bigfoot!"... But as a [former] hunter and frequent outdoorsman, I'm also not quite sure what other animal to compare them to at this time. I also do quite a bit of solo backpacking, so I'm not a novice when it comes to spending nights alone in the wilderness, and encountering large North American animals. It's just this one particular spot that keeps me coming back.
The previous years I went all alone, and the vocalizations were very close to camp. Last time I had an old Hi8 video camera next to my sleeping bag, but of course I was not quick enough to get it turned on and recording in time to catch the screams and howls. It didn't help that I was pretty scared at what I was hearing. The noise was incredibly overwhelming. It made my hair stand on end and my hands were fumbling at the camera controls. These vocalizations were answered by distant coyote calls. I also heard something large "huffing and puffing" and stomping around the camp early one morning (sounded like someone repeatedly making 'raspberries' or blowing out through closed lips).
This year I traveled with my dog, and again I took the Hi8 camera, this time with a extra-large battery pack. The dog is very alert to any noises around camp. Shortly after midnight I began hearing the vocalizations, which woke both of us up. I was almost expecting it, so it doesn't frighten me any more. They were singular "screams" or yells (sometimes two or three in quick succession) which echoed loudly through the forest. No coyote response. This time the vocalizations were more distant, but still clear and distinct. I turned the camera on, and let it record for about an hour... nothing. So, I turned it off to conserve tape (I think the tapes last 3-4 hours on LP mode). Then, an hour or so would pass, and the screams would begin again, with two or three screams before stopping. Again I would press record on the camera as quick as possible, but not quick enough. This happened several times during the night. After the 3rd or 4th time, I left the camera recording non-stop as long as the tape lasted. I have not finished reviewing the entire tape yet to see if I captured anything, but I was not woken up again the rest of the night.
By now you are rolling your eyes... So am I. I hate that I'm hearing these sounds repeatedly, several years in a row now, and have nothing to show for it. Obviously this is a problem with not having a reliable recording device running constantly. I'm hoping to resolve this issue next time and find a digital device which will record 10-12 hours of nonstop high-quality audio, and support external inputs so I can set up a parabolic or omni-directional microphone of some sort. Perhaps those who have invested in such a system can offer suggestions. At this point I'm fairly confident that I can return to this spot again for repeat observations.
