About this map

The Green River and Big Sandy River converge in this arid stretch of the Little Colorado Desert, marking a landscape defined by water management and historic river crossings. The presence of the Lombard Ferry (Site) on the Green River points to a legacy of westward transit, while the Thoman Sch and Hawley Ranch indicate a small but persistent agricultural footprint in the early 1960s.

Survival in this high desert environment required an extensive irrigation network, clearly visible here through the Hamp Ditch No 2, Superior Ditch, and Emigrant Ditch. These man-made channels diverge from the rivers to feed the narrow green corridor of the river bottom, contrasting sharply with the dissected drainages of Eighteenmile Canyon and Lombard Canyon that cut through the surrounding uplands.
