1903 Map of Cuyamaca

About this map

The Cleveland National Forest dominates this expansive look at San Diego County's back country, where the landscape transitions from the developed El Cajon toward the high peaks of the Cuyamaca range. In this era, water management was reshaping the terrain, evidenced by the Cuyamaca Reservoir and the Morena Dam, which served the growing needs of the arid region. The San Diego Cuyamaca and Eastern R.R. connects the lower valley settlements like Lakeside and Santee to the foothills, while the interior remains a network of remote valleys and family-named landmarks. Places like Honey Springs Ranch and the Pine Valley Station mark important stops along the routes through the Viejas Valley and Jamul Valley. To the south, the survey reaches the international border at Tecate, capturing the ranching and early transit corridors such as the Kimball Grade before the mid-century expansion of modern highway systems changed these rural connections.
