A single light flashing all over Mt Ngungun, including well above it and halfway down sheer cliffs.Some friends and I used to rent a house that overlooked the Glasshouse Mountains in Queenland, Australia, which is a location known for UFO activity. One night when we were out the back, I glanced up at the silhouette of Mt Ngungun and saw a light flash near it's highest point. I first assumed it was some campers up there, so didn't pay much attention. Then when I next looked, it flashed in a completely different area, this time I could see that it was a fair distance above the treeline. I pointed it out to my roomies, and we watched as every few seconds it would flash in a different area: sometimes well above the mountain, other times in spots that I knew to be halfway down 50 metre cliffs (I walked and abseiled that mountain quite a few times, so I knew it well enough to pinpoint where the lights were flashing from). Occasionally the lights changed from white to orange, and once red, and at one stage I thought I saw it split into three, although it was back to one a few seconds later. Just for reference too, I realised that my initial thought of it being a camper was ridiculous, as the intensity of the light we saw could never have been produced from a torch, camp fire, or even a spotlight.Eventually the 'light show' slowed until it was a flash every few minutes instead of every couple of seconds, and in the end it just stopped and we went to bed.
