Bright light behind fuzzy cloud.

@1730 .Dark,no clouds. Milky Way present. Son and I heading back to hunting camp. We noticed a very bright light that was directly behind a cloudy,or,hazy substance. There were no clouds . Clear night. This light was coming over Sheep Mountain. Coming from the North and NorthWest. Approximately 15-20 thousand feet in altitude. We were approaching Sheep Mountain to our North, North West. Nearest town from the approach angle is Gunnison, Colorado. Hunting camp near Sheep Mountain was @10,100 feet in elevation. Sheep Mountain is over 13,000 feet. We first thought it was a plane's nose light. Thought it was odd about the haze in front of this light. Son turned his headlamp on,and, this object veered to our left,gradually. Travelling South to SouthEast. Saw no id lights,and, no noise. Did not see an object. Light went off,and sky was clear. No object. Other hunters did not see,or, hear anything.
