Cascade, Idaho - Approx 12am. Went outside for a smoke. I always look up at the stars, particular looking for Mars this night. I noticed a jet in the distance. As this jet moved closer, I realized that this was not a jet. It was about 1000' above deck, and moving at a speed of approx. 150-200mph. It made a faint sound of a jet, but it was not a jet. It looked to be triangle in shape with a bright while light on each corner. In the rear center there was a blinking orange light. it made a rounded 90 turn, continuing at the same speed. I lost sight of the object as it went past the tree line. I do have video of this, however, have not uploaded it, yet.
