“Across Ground” comprises two new books by the Swiss-born, San Francisco–based photographer Lukas Felzmann, who for nearly thirty years has been making poetic images that explore the intersection of nature and culture in California’s landscape. Developed in tandem between 2017 and 2024, the two volumes take us on an allusive journey through the Golden State’s fifty-eight counties, revealing seemingly liminal zones located in between cities, national parks and landmarks. Using a large format view camera, Felzmann follows the border of the continent to the edges of small towns to create a conceptual atlas of the Californian hinterland.
