The light was very small. The size of a distant star and a bluish color. Traveled very fast from top left to bottom right in a very steep angle ~75-80° in a straight path. It appeared that the light was moving infront of the mountain range and may have possibly impacted the south west side of the mountains. I was looking in the general direction before I saw the light. The light appeared then disappeared in under a second. Right before the light disappeared it \"pulsed\" a brighter shade of blue then returned to its normal color before disappearing.
