Montana - Current Level to 1800 feet
Being far enough away from any coastal regions, Montana is not as susceptible to tidal surges or massive coastal flooding. Also, Montana’s lowest point is 1800 feet above sea level on the Idaho border near Troy, making the chances sea levels would get high enough to enter the state almost non-existent. If there was a slow sea level rise that allowed water to make its way into Montana, the affects would probably start on the Missouri River at the states eastern border due to the waterways.

NOTE: The highest tsunami recorded was 1720 feet in Lituya Bay, Alaska.
