4 ambers to red lights appeared for 15-20 seconds then would disappear .4 lights, amber to red color, appeared for 15-20 seconds in the west, then disappeared. seen this happen 4 times in the nite sky. A smoke or haze stayed with the lights but didn't follow the direction of the wind that was blowing out of the west. We watched the lights south of twin falls Idaho while hunting deer in the mountains. The lights were large like fire coming out of a jet engine but would also dance in the sky. We estimated the lights to be 2 miles across in a straight line and would all disappear at the same time. We couldnt see a craft associated with the lights we were looking at them with our binoculars. We estimated the lights to be 15-20 thousand feet in elevation, my hunting friend and I both observed the lights for about an hour and appeared 4 different times in different areas in the west sky.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
