1965 Map of Chuichu

Ephemeral drainages including Santa Cruz Wash and Greene Wash cut across the alluvial plain, while the northern edge shows the expanding residential street grid of Casa Grande. Local industry is evidenced by various Gravel Pits and a Quarry near Sierra N Base. This survey is particularly notable for showing a major interstate highway under construction across the center of the sheet, signaling the shift from a remote ranching and reservation economy to a connected regional corridor.
