The Santa Cruz River corridor serves as the primary axis for development and transit in this Pima County landscape, where the agricultural legacy of Marana meets modern transportation infrastructure. By the early 21st century, the path of the N Casa Grande Hwy dictates the region's growth, marked by major junctions such as the Marana Interchange and the Tangerine Interchange. While the residential street grids of Marana and the settlement at Rillito occupy the valley floor, the terrain rises sharply to the northeast into the Tortolita Mountains and narrows at Rattlesnake Pass in the south.
