1959 Map of Tranquillon Mtn

About this map

The U S Naval Missile Facility dominates the northern reaches of this coastal survey, where the rugged Tranquillon Mountains meet the edge of the Pacific Ocean. Along the shoreline, the Southern Pacific railroad tracks trace the narrow coastal shelf below high bluffs, passing through the small settlement of Sudden. The landscape is defined by deep coastal canyons, including Cañada Honda Creek and La Honda Canyon, which drain the steep interior toward the rocky headlands of Punta De La Concepcion. Inland, the topography rises sharply to Tranquillon Mtn and Wild Horse Peak, marked by a network of jeep trails and remote gaging stations. This area represents a unique intersection of mid-century military expansion and the traditional ranching geography of the Gaviota Coast, preserved here just before the era of intensive space-launch operations at the neighboring base.
