Untitled Sighting

I am 61-yo and have been an outdoorsman all of my life doing numerous backpacking and mountaineering trips in the Cascades and Olympics. I have a degree in psychology from the UW and currently employed as an Investigator. My 15-yo son and I made camp at twilight off FS road 25,  after doing a recon of the Lewis River area for hunting. It is a rain forest there with huge cedar trees and large moss-covered maples reminding me of the Hoh Rain Forest. We set up camp on the east side of a creek. We had my 4-Runner parked and set up a tent. After a steak dinner, I made some howls in the manner of the "Ohio howls" that I had made that had called in a Squatch at Lake Ozette (report #65667). I am a trained vocalist and can project my voice considerably. After no response, we retired for the evening. At approx 10 pm, we were awakened by a loud crack of a branch very close to our tent. I jumped out of my bag with a 400-lumen flashlight and searched 360 degrees hoping to spot the culprit. After several minutes and intense searching to no avail, we went back to sleep only to be woken by howls off in the distance to the south of us an hour later. I would guess that the howls were coming from a single individual approx a mile away from us. My son reported that he had heard footsteps later near the tent that night but failed to wake me. In the morning, my son discovered a single footprint near the tent. I have photos. It is a very wide right footprint approx a size 13 that was very deep (1/2 inch) in the dirt. I am sure the print is still there as it has not rained since drafting this report. Despite a large rock in the near middle of the arch, the print is deep and was not affected by it. I could not make a print at all and I weigh 250lbs. I have always been keenly interested in Sasquatch and was convinced that they exist after reading Dr. Meldrum's Where legend Meets Science book.  I have had encounters after mimicking the Ohio Howl with remarkable success. I suspect the government has proof and is keeping it quiet to protect this cryptohominid with wilderness areas (Lone Butte/Indian Heaven). I am studying maps of an area I reasoned to be prime habitat and have a trip planned overland off-trail/road soon. Time to get serious...
