Thinking with Stone: Deep Time in the San Rafael Swell

By Brian Rajski

An intellectual journey through 250 million years of stone

In the San Rafael Swell, geologic forces have tilted and exposed the strata so that over 250 million years of geologic history can be observed simply by traveling across the rocky landscape, with its dramatic variety of colors and forms. Largely neglected by visitors to the state's national parks and monuments and overlooked by many nature writers of the Colorado Plateau, the exceptional "Swell" offers a unique opportunity to think about people's connections to the layers of earth beneath our feet.

Thinking with Stone takes readers on an intellectual journey across the Swell, moving from the youngest rocks at its edges to the oldest near its center and guiding readers through the features and histories of each geological layer. Drawing on personal experience and scientific research, Brian Rajski explores how creatively engaging with geology by using rocks as the foundation for thinking can generate new ideas about art, ethics, and the environment. Ultimately, the book reimagines the relationships between history and deep time, humanity and geology, and the individual and the stories told by stone.
