Sibley Volcanic Regional Preserve is not just a picturesque corner of nature, but a site with a fascinating geological history dating back 10 million years. It was then that a powerful eruption occurred from the volcano known today as Round Top. However, do not expect to see a classic cone-shaped volcano. Over millions of years, the forces of erosion and tectonic shifts have radically transformed the landscape. Geologists have discovered a striking fact: the volcano was literally overturned by tectonic processes, and what was once the bottom of its crater now forms the peak of Round Top.

The preserve owes its name to Robert Sibley, one of the visionaries and founders of the East Bay Regional Park District. The preserve was officially established in 1936. Its creation was an important part of large-scale efforts to preserve unique natural areas surrounding the San Francisco Bay and to provide access to them for residents and visitors of the Oakland region.

Before becoming a protected natural area, the lands of the future Sibley preserve were used for various purposes. For many years, livestock grazed here, and there was active quarrying of volcanic rocks. This durable material was used in road construction, which was common practice for many areas of the USA with similar geological features. Turning these lands into a preserve allowed their unique volcanic landscape to be saved for future generations.
