1966 Map of Cucamonga Peak

About this map

Cucamonga Peak and the high ridges of the Cucamonga Wilderness dominate the northern half of this 1966 landscape, where deep canyons like Icehouse Canyon and Deer Canyon cut through the Angeles National Forest. To the south, the terrain transitions into the developing alluvial plains of the San Bernardino Valley. Here, established citrus and vineyard-era settlements like Alta Loma, Etiwanda, and Grapeland are laid out on a precise grid of avenues including Sapphire Ave and Haven Ave.
