2015 Map of Blackburn Canyon
USGS Topo · Published 2015About this map
The San Bernardino National Forest dominates this mountain landscape, where the San Jacinto River and its southern fork carve deep relief into the San Jacinto Mountains. Early trans-mountain travel is marked by the winding path of Florida Ave and the Bee Canyon Truck Trl, routes that connect small settlements like Oak Cliff and Alvin Meadows. The geography transitions from the canyon floors of Bautista Canyon and Blackburn Canyon to high-elevation landmarks such as Rouse Hill and Blackburn Ridge. The map identifies several water sources critical for this arid environment, including Halfway Spring and Bautista Spring, alongside seasonal drainages like Dry Cr and Horse Cr. This survey captures a specific network of fire roads and trails, such as the Old Control Rd near Toll Road Canyon, which supported forestry and regional access during this period.
