The flight path crosses the Blue Mountains of northeastern Oregon (visible around 30 minutes into flight), then the Wallowa Valley and Eagle Cap Wilderness. The Grande Ronde Valley appears as a distinctive open basin surrounded by forested ridges. As the aircraft approaches Idaho, the Wallowa Mountains (with Eagle Cap at 9,572 ft) form a dramatic alpine ridge on the right side. The flight then crosses into Idaho's high plateau country, with the Powder River drainage visible below. The Bitterroot Range becomes prominent on the right as the aircraft descends toward Missoula, with the range running north-south and forming the Idaho-Montana border. The Flathead Lake region becomes visible on the left during final descent.
