Roberts Island and the surrounding delta tracts define this 1911 survey, showing a landscape engineered for intensive agriculture and river-borne commerce. The territory is divided into massive agricultural units like the Lower Jones Tract and Wright Tract, separated by a complex network of waterways including Whisky Slough and Trapper Slough. The concentration of river access points, such as Blackslough Landing and Eldorado Landing, illustrates how vital the San Joaquin River was for transporting crops before the total dominance of overland trucking.
