A beautiful 1852 map of Great Salt Lake, especially striking for its use of unusually artful hachuring (rather than contour lines) to convey topography. Hachures provide an impressionistic geovisual scheme of topographic barriers. When rendered skillfully, they can be more effective than contours at opening visual space for other kinds of map features. Full map is hosted on the David Rumsey Map Collection site (see link below).
