Shape shifting light in sky in remote forest locationMyself and three friends were camping in the forestry reserve approximately 40 kilometres North of Cochrane, Alberta. There was a total fire ban at the time due to the high risk of wildfires, so it was absolutely dark. Around 2:30 in the morning we were sitting around our picnic table in the dark, when suddenly we noticed a strange light in the southwestern sky that hadn't been there moments before. The light was white, and at first it was about as bright as the brightest stars in the sky. However, as we watched the light grew brighter and brighter, although it appeared relatively stationary over one point of the valley, quite high in the sky. Eventually the light was brighter than any star or planet could be. I don't think it was a helicopter, because we would have heard a helicopter in the still night, but this light made no noise. As we continued to watch the light, it would move up and down and side to side in the air, but not very much. It also grew brighter and dimmer at intervals. As we watched, the intense bright light faded again, and eventually vanished completely. The sky in that area was dark again. Moments later the light reappeared in the same spot, and soon it was shining brightly again. The way the light waxed and waned reminded me of watching a lighthouse from a distance, where the light gets brighter, then fades away, then reappears. We continued watching the light for about 45 minutes. In this time the light gradually moved away from us in a southwesterly direction. We noticed that in addition to moving up and down and side to side, the light would appear to change shape, sometimes seeming to be two connected points of light, sometimes one large round point of light, sometimes a square shaped light. The light would also seem to change colour - it was dominantly white, but sometimes seemed orange or green in colour. The object was still in the sky when we went to bed, but it did not return the next night.
