Join Pegasus Downtown on Thursday, June 1st at 7pm as they welcome Andrew Alden, author of Deep Oakland: How Geology Shaped a City. Alden will give a talk about Berkeley geology followed by a Q&A. Books will be available for purchase and signing at the event.

In Deep Oakland, geologist Andrew Alden excavates the ancient story of Oakland’s geologic underbelly and reveals how its silt, soil, and subterranean sinews are intimately entwined with its human history–and future. Poised atop a world-famous fault line now slumbering, Alden charts how these quaking rocks gave rise to the hills and the flats; how ice-age sand dunes gave root to the city’s eponymous oak forests; how the Jurassic volcanoes of Leona Heights gave way to mining boom times; how Lake Merritt has swelled and disappeared a dozen times over the course of its million-year lifespan; and how each epochal shift has created the terrain cradling Oaklanders today.
