Outflow boundary a downburst. "Gustnadoes", short-lived vertical circulations near ground level, can be spawned by outflow boundaries. Gust fronts create low-level wind shear which can be hazardous to planes when they takeoff or land. Flying insects are swept along by the prevailing winds. As such, fine line patterns within weather radar imagery, associated with converging winds, are dominated by insect returns. At the surface, clouds of dust can be raised by outflow boundaries. If squall lines form over arid regions, a duststorm known as a haboob can result from the high winds picking up dust in their wake from the desert floor.
Amargosa Desert Death Valley to the west, and Yucca Mountain and the Nellis Air Force Range to the east. The Amargosa Desert is an arid desert habitat and an ecotone between the northern Great Basin and southern Mojave Desert ecosystems and biogeography regions. The seasonal Amargosa River course runs through the desert, with the rare Shoshone pupfish in nearby Amargosa Pupfish Station of the Desert National Wildlife Refuge Complex. It is not known when the first humans settled in the Amargosa Desert. Ancient campsites have been found that date back at least 10,000 years, to the end of the last ice age.
