The Big Sioux River snakes through the heart of this landscape, its winding course defining the agricultural character of eastern South Dakota. In the early 1960s, the rail infrastructure remains a dominant feature, with the Chicago Milwaukee St Paul and Pacific line connecting the settlements of Egan and Trent. The junction near Sioux Falls Junction highlights the importance of these transport corridors to the regional grain and gravel industries, evidenced by numerous Gravel Pits distributed along the river valley.
