That is Little Lookout. Big Lookout would be just to the right of that picture. I don't know if they are considered a portion of a mountain range. Too far south to be part of the Wallowa Mountains. Too far east to be considered part of the Blues. This picture is Big Lookout. Big Lookout is about 7,150 feet. Little Lookout is around 6,300 feet. From the top of Big Lookout you look nearly straight down at the Snake River and across the river at Idaho.What mountains are those?
