When the first explorers, trappers, and farmers entered the Salt River Valley, they were quick to note the impressive ruins left by the Hohokam.

Villages containing platform mounds, elliptical ballcourts and trash mounds covered with broken ceramic pots and other artifacts existed throughout the valley.

The Hohokam engineers were keenly aware of the local topography, the dips and slopes, drainages and soils.

They developed a sophisticated knowledge of the flow of water through channels and developed a series of techniques for delivering water to the surface of the fields.

Little is known about these people who established the first small hamlets along the terraces above the Salt River.

They appeared to have lived a sedentary agricultural lifestyle, establishing fields along the margins of the river. 50, these early inhabitants introduced a new technology, canal irrigation.

The most extensive records were made by Frank Midvale, an archaeologist who devoted his life to recording the traces of the Hohokam as the remains of their culture were destroyed by the rapid expansion of modern agriculture and urban growth.
