Transcontinental Arch
The Transcontinental Arch refers to the islands of North America which extended from New Mexico to Minnesota and the Great Lakes region. [1] These islands were present during the Sauk sequence, the earliest cratonic sequence. As a result of the Sauk sequence, epeiric seas covered most of North America, leaving only the craton of the Canadian Shield and the Transcontinental Arch islands exposed.
