About this map

Boulder City occupies the northwestern corner of this quadrangle, where the urban boundary meets the open expanse of the Mojave Desert. The landscape is defined by the dramatic shift from the flat floor of the Eldorado Valley to the rising elevations of the southern McCullough Range, a transition clearly visible in the contour density. A critical water source in this arid environment is documented at Water Plug Number Two Spring, located in the higher terrain to the east.

Keyhole Canyon cuts through the mountains, serving as a primary drainage and topographical landmark. The map detail reflects a modern surveying era, showing the primary highway corridor heading south from the city while remote tracks like Grandpa's Rd provide access to the desert interior. This 2018 survey provides an exact record of the municipal limits and the natural desert features that constrain the growth of this iconic Nevada settlement.
