Elkhorn Mountains
The first major landform seen immediately south of Helena, known for its dense forests and wildlife.
Wind River Range
One of the most spectacular sights in the lower 48, featuring Gannett Peak and jagged granite spires.
Medicine Bow National Forest
Dense alpine forests and the high peaks of the Snowy Range visible near the Wyoming-Colorado border.
Rocky Mountain National Park
A sprawling view of protected wilderness including the famous Trail Ridge Road area.
Longs Peak
The most prominent 14,000-foot peak in northern Colorado, often passed closely during the descent into Denver.
The right side is essential for seeing the most rugged terrain. For the best photography, choose a mid-afternoon flight when the sun illuminates the western slopes of the Wind River and Front Range. During the approach to DEN, keep your camera ready for Longs Peak and the dramatic transition from the mountains to the urban sprawl of the Front Range corridor.

Canyon Ferry Lake
Visible shortly after takeoff, this massive reservoir on the Missouri River sits just east of Helena.
Big Belt Mountains
A rugged range forming the eastern boundary of the Missouri River valley near Helena.
Bighorn Mountains
The dramatic Cloud Peak Wilderness is visible in the distance as the flight crosses into northern Wyoming.
Casper, Wyoming
The flight often passes directly over or just west of this historic oil town along the North Platte River.
The High Plains
Expansive views of the rolling shortgrass prairie where the mountains meet the Great Plains.
Early morning flights provide excellent lighting on the eastern faces of the mountains. Watch for the sharp contrast between the green Missouri River valley and the arid hills of central Wyoming. On clear days, the white limestone of the Bighorn range is a distinct landmark halfway through the flight.
