San Francisco Bay in laser-cut Baltic birch: one of the world’s great natural harbors carved layer by layer, from the Golden Gate’s deep throat to the shallow southern reaches. Angel Island rises mid-bay, Alcatraz holds its rock, and the cities ring the whole basin from the Embarcadero around to Sausalito’s houseboats. Two great river systems arrive through the Delta at the bay’s back door, fresh water meeting salt in the largest estuary on the West Coast. The birch holds all of it in true proportion. Contours are laser-cut sheet by sheet, stacked by hand, engraved, and finished behind acrylic glass in a solid Baltic birch frame in Dark or Light. Ferry riders, bay sailors dodging the ebb, and everyone with a bridge in their window: this is the water that explains the place. The engraving spans the Gate and both bridges, Alcatraz and Angel Island, the city front, Richardson Bay, and the reaches south. Companions: the Golden Gate close-up and the California Coast. Wood charts of real waters, cut from survey data. Companions: the Golden Gate close-up. And the California Coast. 16 × 20 in or 24.5 × 31 in. Solid Baltic birch frame in Dark or Light. Acrylic glass front, ready to hang. Every contour follows real bathymetric survey data. Each water is cut from its own chart to its own shape, so the shoreline, shoals and channels are the real ones. The pale land is the bare wood. The water is stained by hand and darkens as the bottom falls away. Grain and tone vary slightly from piece to piece, so no two are exactly alike. Questions about a specific water, a size or a frame are welcome. Real people read every message. More waters from Nautical Lake Art.
