This was the strangest thing I had ever seen camping in such a remote area. Later at night a large series of cars came up to the beach area and parked all up along the granite rocks for some party. I thought to myself it sounds more like a ritual as multiple people with torches, hoods and dressed in black passed by us to make there way around the northern edge of the lake. I pulled out the camera to film there torches flickering not sure what they were doing but I do know the grass near the north end of the lake and foliage is very dry. I think my major concern would have been a forest fire and we would be forced to have to retreat leaving behind our camp. In addition to strangeness prior to shooting this video I seen a green fireball that was burning up on and off in our atmosphere.
