Introduction
The drive from Twin Falls, ID to Livingston, MT spans roughly 370 miles along US-20, US-26, and I-15, crossing the Snake River Plain and the Continental Divide. One notable fact: the route passes near the site of the 1959 Hebgen Lake earthquake, which created Quake Lake in Montana. This road trip offers a transition from Idaho's volcanic landscapes to Montana's Rocky Mountain splendor.
