About 500 million years ago, a shallow sea covered the area, laying down layers of sand and minerals that make up much of the sandstone bluffs now seen along the river.

Middle East (Wikipedia) The Middle East (term originally coined in English) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term “Middle East” has led to some confusion over its changing definitions, and being seen as too Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus, and additionally includes all of Egypt (not just the Sinai) and all of Turkey (not just the part barring East Thrace).

The lower 125 mi (201 km) of the river form the border between Wisconsin and Minnesota. The river is a National Scenic Riverway under the protection of the National Park Service. A hydroelectric plant at the Saint Croix Falls Dam supplies power to the Minneapolis–Saint Paul metropolitan area.
