Where two mighty rivers meet. This state park is rather small as state parks go, and is more notable for its history and geological significance than its beauty. Driving from St. Louis to Alton, Il, you’ll come to a great area for eagle watching in the winter. You’ll have to drive a ways off the road, and then a long ways down a dirt road through fields to actually get to the park. There is a nice write-up on the different indian nations that lived in the area, as well as a nice monument for the meeting of the Missouri (aka the “Big Muddy”) and the Mississippi. This also marks the launching point for Lewis and Clark on their great expedition. Worth seeing if you’re in the area and are out sight-seeing.
