Twin Falls is south-central Idaho's largest city on the Snake River canyon rim, with earthquake risk from the Snake River Plain fault system and increasing wildfire exposure from surrounding sagebrush steppe terrain. The Snake River canyon and Shoshone Falls draw significant tourism. The Magic Valley region's dairy and food processing economy depends on Snake River water, making infrastructure disruptions especially consequential.
