Wood Chart map of the San Francisco Bay.
A shallow, productive estuary, San Francisco Bay connects the Sacramento and San Joaquin rivers with the Pacific Ocean. Gathering the rainfall and snowmelt from an enormous watershed, these outflows drain approximately 40% of California into the bay, which then flows out (under the Golden Gate Bridge) into the Pacific Ocean. It's the largest Pacific estuary in the Americas and, despite significant mining- and construction-related damage over the past century, it remains a rich part of the coast'
Starting with a bathymetric chart (the underwater equivalent of a topographic map), we use laser-cutters to carve the contours into sheets of Baltic birch and glue them together to create a powerful visual depth. We hand stain select layers blue so it's easy to discern land from water, etch major byways into the land, then frame the whole thing in a custom, solid-wood frame and protect it with a sheet of durable, ultra-transparent Plexiglas.
