Cowlitz County Washington (Class B) BFRO

May 2023

We were camping at Merrill Lake Campground in Washington, about 10 miles southwest of Mt. St. Helens, when we heard one single tree knock. It occurred around 2230 as we were sitting around the campfire relaxing. We were camping on the east side of Merrill Lake and the knock sounded like it came from the west side of the lake, approximately .5 to 1 mile away. We did not see any lights on the opposite side of the lake, where the knock came from, nor did we see anyone on that side of the lake earlier. The night was clear, no wind, and during the weekday. The tree knock sounded similar to a baseball bat hitting a tree and did not sound like a limb falling.
