Former habitation is noted at Lujane and Cedar Creek, indicating areas where settlements have given way to more modern utility, such as the Montrose Reservoir and the Microwave Relay Station. The map illustrates a shift from the pioneer-era camps of Ellison toward a landscape increasingly defined by water management and communication systems, all set against a backdrop of deeply etched drainages like Hairpin Creek and Rawhide Gulch.
