La Crescent Township is an urban township with a majority of the land consisting of agriculture, forest land and numerous residential developments. In fact, the township is somewhat unique among townships within the county because of its diverse land area and development.
Perhaps the most distinguishing natural features in the township are the steep bluffs covered with hardwood forests and a number streams, and lowlands cutting through the bluffs. Some of the streams represent environmentally sensitive areas in that they are classified as trout streams. The Mississippi River including a number of major sloughs run along the eastern border of the township and serves as a source of recreation as well as river commerce.
