📝 Description
I was hiking at Little Si in Washington State with a friend who was visiting from out of town. It was pouring rain so we left our phones but we went anyway and started our hike sometime in the morning. We got to an interesting little part off the trail where a little waterfall was pouring off from a cliff above, maybe like 20 feet up. We turned back after that spot and started heading back but while we were walking we heard what I first thought was an alarm, but it sounded organic. At the end of the �alarm� was a very strange vocalization like an ape mixed with human. The alarm sound happened over 10 times and at the end of each sustained holler was the strange vocalization. After the second or third alarm sound and vocalization I started making the sounds back to whatever it was. My friend and I both listened intently trying to identify what the sound could possibly be. We ruled out human right away because whatever was making that sound had a huge lung capacity and we both immediately knew it couldn�t be human. As we listened, and I kept responding, the way the mouth moved made us also rule out a wolf or coyote. It sounded like it had lips...I know that sounds strange but we both said whatever was making the sound had a mouth like a human or ape. I responded three or four times before I realized what else it could possibly be. �Amy, we gotta go. NOW� I said. She asked why and I said, �I think I�m hitting on a Sasquatch. We have to get the hell out of here.� I know I�m making it sound like a joke, but I grew up hearing about Sasquatch stories and I never thought they could be actually real. So I was a little joking when I told her I was hitting on a Sasquatch but the sound was so large, reverberating through the mountainside, I also thought whatever that is sounds like it�s getting closer and the only thing it could possibly be, however unlikely, was a large beast with lips like a human or ape. So, we ran. We ran the rest of the way down the trail and got to the car where our phones were. We didn�t see anyone else on the trail. When we got our phones out I googled Pacific Northwest wildlife sounds to try and find out what it �really� was. We looked up wolf, coyote, elk, and anything else we could think of. So I finally said, �We have to look up Bigfoot sounds...it�s the only thing left.� She looked at me and nodded. She didn�t grow up hearing any stories of Bigfoot because she is from the Midwest. I found a few recordings and immediately the hair on our arms and neck stood straight up. This was 5 years ago but just writing this I�m getting goosebumps all over again. I was at an art sale today in Leavenworth and a man was selling art. We bought a painting with a Sasquatch standing behind a tent and it reminded me of this story. That artist doesn�t really know much about Sasquatch but said since painting them he�s heard countless first hand stories from people out there and so I shared mine with him. It made me want to see if there was anyone else who would want to know, and my brother sent me here. Anyway, thanks. It feels good to get this experience out to the right people. I�m still skeptical but cannot deny what I heard, and I still have no explanation for it. The vocalization I heard was very similar to the Sierra recordings (forgot the name of the guy who recorded them) but the sustained big barreled �alarm� with the sounds at the end was a bit different than those recordings. I was going to change the date because it happened on October 31st, and I thought no one would believe me. But it is what it is. Also, we were so freaked out that I left a note warning other campers and made an email address asking if anyone else heard it, to contact me. No one has (I haven�t checked it in years, however).
