YEAR: 2020

SEASON: Fall

MONTH: December

DATE: 16

STATE: Washington

COUNTY: Skamania County

LOCATION DETAILS: Near the Marble Mountain Sno-Park going up the Worm Flows Trail.

NEAREST TOWN: Cougar WA

NEAREST ROAD: Forest Road 83

OBSERVED: I went on a 6 mile hike starting at the Marble Mountain Sno-Park via the worm flows route south of Mount St. Helens.
At 9:30am 1/2 mile up the trail I stopped for some water and stepped over to look at the rock pit. While stepping back to the trail I heard loud wood knocking sounds for about 10-15 seconds.
I listened for a few more seconds and then got my phone out to record the knocking sounds. In my recordings you can hear one powerful knock followed by faint knocking sounds. In my longer video I believe three different knocking locations can be detected. Starting with one loud strike of a tree followed by faint knocking and then a more muffled hit followed by the same faint knocking sounds.
Hoping to video anything moving around, I decided to continual my hike going up another 2.5 miles until inclement weather rolled in.
I made it back to my truck at 4pm without seeing or hearing anything else.
With me being the only one parked at the Sno-Park when I started my hike it's clear nobody was near me at the time of the knocking. Forest road 83 is gated for the winter with only the Sno-park open.

ALSO NOTICED: Crows were going crazy at the Sno-Park prior to my hike.

OTHER WITNESSES: I was alone.

OTHER STORIES: I've seen a fresh small foot print with water still seeping in at the Kalama river. Heard vocalizations at Hoffstadt Bridge with coyotes responding. Heard vocalizations 29 years ago at Green river at the wash-out. A rock was thrown in front of my car at Elk Rock about two months ago. Seen a black figure run up Mt. Adams at the lunch counter. 26 years ago saw about 12 black figures (hikers?) walking West to East on Mt. St Helens on the June lake side.

TIME AND CONDITIONS: 9:30 am
Good and clear with no wind.

ENVIRONMENT: It's in uninhabited forest next to a rock pit.

Follow-up investigation report by BFRO Investigator Greg Keech:

The witness was hiking in snow and the most recent tracks on the trail appeared to be a couple of days old. It is unlikely the noises were of human origin since there are no other dwellings in the area nor any other roads open (due to winter closures) that would facilitate recreational activity in the vicinity the knocks were heard.
The witness estimated the loud powerful knock sounded less than 1000 feet away. Other knocks were subsequently heard coming from two separate locations which were perceived to originate some greater distance away. The witness asserted the knocks suggest up to three Sasquatch actively communicating with each other.
