About this map

The Santa Ana River and its accompanying Santa Ana Wash dominate the central valley landscape of this late nineteenth-century survey, illustrating a critical era of irrigation and expansion. Established settlements like Redlands and Mentone are shown alongside extensive water-management systems including the Highlands Ditch, California Ditch, and Redlands Canal. These features highlight the region's transition into a premier citrus-growing hub, supported by the Southern Pacific and the San Bernardino Motor Line.

To the north, the terrain rises into the San Bernardino National Forest, where local landmarks such as Squirrel Inn, Tollhouse, and Guerneys Mill mark the mountain passes. The presence of the Asylum near Patton and the residential development at Smiley Heights provide unique genealogical touchpoints for researchers tracing the early social and industrial infrastructure of the San Bernardino Valley.
