Mountain pass in United States
Monida Pass is a high mountain pass in the northern Rocky Mountains of the western United States , at an elevation of 6,870 feet (2,094 m) above sea level on Interstate 15 , and 6,820 feet (2,079 m) on the Union Pacific Railroad .[citation needed
On the Continental Divide in the Bitterroot Range , it marks the transition between the Beaverhead Mountains and the Centennial Mountains . Its name is derived from the states that it separates, "Mon" from Montana and "-ida" from Idaho .[ 1]
The pass forms part of the border between eastern Idaho and southwestern Montana , and is between the towns of Spencer in Clark County and Lima in Beaverhead County . On the Idaho side is Beaver Creek running through Beaver Canyon, which was the route of the Utah and Northern Railway in 1880 and is still used by Union Pacific.[ 2]
