About this map

Christmas Mtn serves as the central topographic focal point of this mid-1950s survey in Ada County. The landscape is defined by its open terrain and specialized land use, including a distinct Rifle Range and an associated Target located to the north. These features, along with a remote Landing Strip and several survey markers like Reptile VABM 3497, suggest a period where the area was utilized for both military or recreational training and aerial navigation.

To the east, the topography transitions toward notable geological formations such as Flagstaff Butte and the subterranean features of Higby Cave and other Caves. The presence of the Boise Base Line across the northern edge of the sheet emphasizes the foundational surveying work conducted by the Geological Survey during this era, capturing a sparsely populated Idaho landscape before significant suburban or commercial expansion altered the region.
