Phoenix is defined by a complex network of irrigation ditches and canals that drive the agricultural development of the Salt River valley. This 1912 survey, reprinted in 1946, shows the early urban grid of the city surrounded by foundational infrastructure like the Grand Canal, Salt River Valley Canal, and Western Canal. To the south, the Salt River Mountains provide a natural barrier above the Gila River Indian Reservation, where St Johns Chapel and Maricopa Village are established. Notable social landmarks of the era are recorded, including the Indian School, the State Hospital, and the County Poor Farm. Transportation is anchored by the Santa Fe Prescott and Phoenix RR, while isolated industrial sites like the Gold Coin Mine dot the southern foothills.
