On April 18, 1906, a massive earthquake centered just west of San Francisco ruptured the earth from Humboldt to San Juan Bautista. While the more dramatic traces of this 7.8 temblor may be hard to find one hundred years later, the tectonic forces that moved the earth that day are still relentlessly shaping our young and active landscape, carrying us towards another cataclysm in the near future.

All of the familiar landforms we see here in the Bay Area—ridges, cliffs, lakes, and even San Francisco Bay itself—are products of the same titanic encounters between tectonic plates that produce our frequent quakes. Through a geologist’s trained eye, we learn to interpret the signs these forces have left on the land around us.

Trails are the main way we access most of the Bay Area’s diverse and abundant open space. Despite that, it’s easy to forget that trails have to be planned and built by someone. However, for the East Bay Regional Park District, which has over 1,000 miles of trails, this is a full-time job. At places like the newly-opened Brushy Peak Regional Preserve, trail planners must balance people’s desire for access with the needs of native plants and animals.

Not many people get to visit Año Nuevo Island—you need a rubber boat, a strong stomach, and a research permit. But sea lions haul out here in droves, and hundreds of seabirds—including rhinoceros auklets—come to breed on its few wind-swept acres. Today, erosion is threatening the auklets’ deep burrows, so researchers are working to restore this critical breeding site for these strange-looking seabirds.
