1983 Map of Twin Knolls

About this map

Twin Knolls and the surrounding high desert of Emery County appear here as they were documented in the mid-1970s and early 1980s. The landscape is defined by its water-carved topography, where drainage systems like Reid Neilson Draw and Crawford Draw cut across expansive plateaus like Indian Flat and Paige Flat. This map is particularly valuable for its recording of isolated water sources and livestock improvements in an arid environment, including The Big Pond, State Pond, and the curiously named Woodpile Pond. Evidence of land use and exploration is scattered throughout the terrain, from several Drill Holes and Prospects near Block Mountain to the network of unimproved routes like Earls Road. Named natural features such as Lone Man Butte and Ernie Canyon provide distinct landmarks for navigating the complex system of washes, notably the prominent Iron Wash that dominates the southern portion of the quadrangle.
