Solid body triangle with four lights hovering over the lake next to the u-neek rv center in kelso. wa. while driving toward the lake i saw a large craft shaped like an equilateral triangle it had a dark blue/black body slightly brighter in color than the evening sky, and had four lights. one corner had both a turquoise and a white light and the other two corners had red and blue lights. it hovered over the lake and slowly rotated as our vehicle passed, just as we pulled off to the side of the road to observe it it took off at rapid speed west toward longview junction.
