I observed one main big light about a mile and a half in the distance. this main light moved up and down slowly and pulsated glowing brighter to a very faint light. the object hovered and had a very bright light, then it dimmed, this continued, it grew dim as it moved up and down. smaller object (lights) came out of the main light in both directions (left & right) the lights moved out farther that the main light moved up and down. these lights also slowly pulsed. the smaller objects moved vertically and made smaller arcing paths from the larger one. mostly they moved in strait lines to and from the larger one. this occurrence lasted over 20 minutes, from a distance over a mile away. this took place over a heavy pine forest with no population below or around the lights. it took place in a mountain valley with small mountains behind and to the sides of the lights. no obstructions were in place between me the the lights. very little cloud cover, if any.
