Mackay and its surrounding high-desert landscape are defined by the managed waters of the Big Lost River, which feeds the expansive Mackay Reservoir. This 2013 survey illustrates the complex relationship between the valley's agricultural needs and the dramatic topography of the Challis National Forest. The map documents numerous landmarks essential to the area's identity, from the historical Battleground Cem near the reservoir's northern shore to industrial remnants like the Cossack Tunnel found in the southern reaches of the quadrangle.
