2018 Map of Azusa

About this map

The San Gabriel Mountains dominate the landscape of this 2018 survey, rising sharply above the urban expansion of the San Gabriel Valley. The transition from the dense residential grids of Azusa, Glendora, and Duarte to the steep, undeveloped slopes of the Angeles National Forest is immediate. This interface is marked by complex water management systems, including the Morris Reservoir and the San Gabriel River, alongside critical infrastructure like the Sawpit Wash and various debris basins designed to protect the valley from mountain runoff. Higher elevations are characterized by a network of fire roads and truck trails, such as the Rincon Red Box Truck Trl, which navigate peaks like Monrovia Peak and Mt Bliss. On the valley floor, the map details established educational and medical institutions, including Citrus College and the City of Hope Graduate School of Biological Sciences.
