i went to see 'San Andreas' last weekend. it's rather cheesy movie. but it got me interested in the San Andreas fault. after some look online, I realized that at one time there's an inland sea existed between Rockies in the west and Appalachian mountains in the east. but wiki shows it as waterway instead of an inland sea.
so did an inland sea exist at some point?
