About this map

The San Bernardino Mountains and the San Bernardino National Forest dominate the northern landscape of this map, giving way to the urban development of Yucaipa and Calimesa to the south. Significant water management infrastructure is visible throughout the terrain, including the historic The Zanja and the Redlands Aqueduct. These systems, along with the Bear Valley High Line Aqueduct, trace the historical effort to divert water from the Santa Ana River and Mill Creek to support the citrus groves and expanding settlements of Redlands and Mentone.

Transitioning from the heights of Cram Peak and Morton Peak, the topography descends into the Yucaipa Valley. Educational and residential expansion is marked by Crafton Hills College and neighborhoods like Dunlap Acres. The map also details a dense network of mountain fire roads and recreational trails, such as the Crafton Hills Ridge Trl and the Morton Ridge Trl, illustrating the interface between the wild Crafton Hills and the established communities below.
