1972 Map of Whistler Canal

About this map

The Bear River Migratory Bird Refuge dominates this 1972 orthophotomap of the marshy delta in Box Elder County. This specialized hybrid sheet combines aerial imagery with traditional topographic contours to document the complex water management systems of the era, including the Whistler Canal, Corinne Canal, and various laterals designed to move water across the expansive Alkali or Mud flats. The landscape is defined by the winding course of the Bear River, which carves distinctive features such as Whistlers Bend and Glory Hole before reaching the vast expanse of Willard Bay.
