1989 Map of Delta

About this map

The irrigated basin of the Sevier River dominates this landscape, showing a network of canals and reservoirs that sustain agricultural settlements like Sugarville, Woodrow, and Abraham. In the late 1980s, the map highlights the proximity of the historic Topaz Camp northwest of Delta, providing a significant reference for researchers of World War II history. The eastern edge is defined by the steep elevation of the Fish Lake National Forest and the Pahvant Range, contrasting sharply with the broad Pahvant Valley below. Evidence of the region's volcanic past is visible at Pahvant Butte and the basalt flows of The Cinders, while the massive, often dry basin of Sevier Lake sits to the west. Transportation is anchored by the Union Pacific Railroad and Interstate 15, which connect these desert communities and managed wetlands like the Clear Lake Wildlife Management Area.
