The Blue Ridge Mountains are a physiographic province of the larger Appalachian Mountains range. This province consists of northern and southern physiographic regions, which divide near the Roanoke River gap.
The Blue Mountains were the last mountain range that emigrants on the Oregon Trail had to cross before reaching the Columbia River gorge and the valleys east of the Cascades. It was also a very formidable crossing.
