Rocks thrown at two hikers on Heather Lake Trail

1999–2000 About 4-5pm, daylight Granite Falls, Snohomish County, Washington 2 witnesses

Account

Around 2001 the witness and a companion hiked Heather Lake Trail in the late afternoon as the last hikers on the trail. While taking turns stepping away to urinate near the top, each had a rock thrown at them from an unseen source. As they hurried and then ran back down, they heard heavy stomping and breaking branches moving parallel to them, and another rock was thrown after they briefly hid behind a tree, prompting them to flee to their car frightened.
