Census Physical Features, 1995 - Arizona

These features are neither transportation nor hydrographic in nature but may be used to determine boundary lines. The predominant Feature Codes in this layer are E00 (Physical feature, major and minor categories unknown); E20 (Topographic feature; major category used when the minor category could not be determined); and E21 (Ridge line, the line of highest elevation of a linear mountain).

Additional features which may be identified in this, or other layers, include: Fences: Fence lines locate a visible and permanent fence between separately identified property. For example, a fence around a military reservation or prison separates the reservation from civilian land. Thus, a fence line is a property line marked by a fence.
