Report 69270: Possible Sasquatch howls north of Leavenworth, east of Lake Wenatchee

My name is Niels Nelson.  I stay/live in a travel trailer at Thousand Trails Leavenworth, WA. However the resort is 18 miles away from Leavenworth outside of Plain, WA. I was awakened by a sound... No clue what woke me but with it being Memorial Day weekend and many in the campground I just assumed it was someone being loud and and it woke me. I didn't really hear what woke me so laid my head back down on the pillow and about 3 minutes later I heard something but I was awake and sat up in bed and listened. My first thought it was a bigfoot howl or yell, as it seemed so distant but so filling of the entire forest/valley. I said to myself nah it must be some humans partying or yelling at a cabin on a hill, or in another section of the campground. Then within another 30 seconds another one while I was still sitting up, head by the open window, and complete darkness, no other human noise, quiet time and all are sleeping, and no human could make this noise as we simply cannot transmit what I will call depth and broadness of that kind of distance. It felt like it was coming from miles away but it wasn't directional. This howl could pentrate walls or obstructions it felt like. This was beyond weird, unsettling, while still kinda exciting. Anyhow, that is what I heard.
