Alexander Pisch, 35, was last known to be near Colonial Creek Campground in the Diablo Lake area of North Cascades National Park on October 8, 2020. He is described as a white male, 6 feet 1 inch and about 160 pounds. His white Toyota Corolla was found parked along Highway 20 near where he had set up an easel for painting, but his intended route or destination was not known.

Two days later a National Park Service employee found the car and easel still in the same spot and reported no sign that Alexander was nearby. Rangers and search teams were then deployed to examine Colonial Creek Campground and the surrounding Diablo Lake area; by October 13 the search included about 20 personnel working terrain that includes forest, steep slopes and cold water.

Does anyone who was in the Diablo Lake or Highway 20 area that weekend have information that could help?
