Published in 1935, the U.S. Geological Survey’s “Sebastopol” presents a richly detailed 1:48,000 view of western Sonoma County and its neighboring landscapes, with Occidental, California, standing out amid the folds of coastal terrain. Labeled as an “Advance” map, it captures a region in the midst of careful federal survey and classification, when roads, trails, streambeds, and settlement patterns were being recorded with scientific precision. The map’s distinctive brown contour lines give immediate shape to the land, revealing the ridges, valleys, and drainage systems that define the country between Santa Rosa, Bodega Bay, the Russian River, and the Pacific Ocean. It is both a practical topographical document and a historical portrait of a rural California landscape before later waves of residential growth.

The U.S. Geological Survey brought to this map the authority and discipline that made its topographical series indispensable to engineers, planners, geologists, foresters, and travelers. Founded in the late nineteenth century, the USGS became the standard-bearer for systematic American mapping, translating field surveys into elegant, information-rich sheets where elevation, hydrology, transportation, and habitation could be read together. In “Sebastopol,” that tradition is visible in the clarity of the contouring and the careful notation of creeks, valleys, roads, and settlements. The “Advance” designation adds particular interest, suggesting a map issued ahead of a finalized edition, preserving a moment in the evolving process of federal cartography. Its style is restrained but deeply expressive, allowing the terrain itself to provide the drama.

Occidental appears within a landscape of remarkable topographic variety, its rural setting framed by the coastal mountains and a web of stream systems descending toward larger waterways. Severson Creek, Hinebaugh Creek, Armstead Creek, Salmon Creek, and numerous tributaries articulate the terrain, their courses threading through valleys and wooded slopes. The dense contouring around these drainages suggests steep ridges, narrow hollows, and the rugged character typical of the Sonoma Coast hinterland. Nearby places such as Freestone, Graton, Green Valley, and Freestone Valley evoke a countryside of small agricultural communities, orchard lands, forested hills, and local routes binding the region together. The map is especially evocative for showing Occidental before its later reputation as a retreat among redwoods and rolling coastal hills became widely celebrated.

The broader geography gives the map an appealing sweep from inland valleys toward the maritime edge of northern California. To the west, Bodega Bay, Tomales Bay, and the Pacific Ocean anchor the sheet in the coastal world of fog, fisheries, headlands, and tidal inlets. To the north, the Russian River and the historic vicinity of Fort Ross recall older layers of settlement, trade, and exploration along the Sonoma coast. Inland, Santa Rosa and the surrounding country point toward the agricultural and civic heart of the county, while Sonoma Mountain, Burdell Mountain, the Petaluma River, Tocaloma, and Marin County extend the map’s geographic conversation southward and eastward. This interplay of coast, river, mountain, and valley gives the composition unusual richness.

As a historical document, “Sebastopol” records a transitional California landscape: still largely rural, yet already threaded with the roads and trails that would shape twentieth-century movement and development. Since 1935, parts of Sonoma County have become more residential, closely tied to Santa Rosa and the greater Bay Area, while other areas have retained their pastoral, forested, and conservation-minded character. The map preserves the earlier pattern of dispersed communities, creekside corridors, and terrain-governed routes, before modern infrastructure softened the isolation of places like Occidental and Freestone. Its contour lines reveal why settlement followed valleys and ridges rather than abstract grids. For collectors, it offers not only topographical beauty but also a refined glimpse of western Sonoma County at a pivotal moment in its modern history.

Detailed maps are especially rewarding at larger sizes, where names, boundaries and decorative features have more room to be appreciated. Use the close-up preview and size guide to choose the right scale for your wall.

This map looks amazing at sizes all the way up to 50in (125cm). If you are looking for a larger map, please get in touch.

The model in the listing images is holding the 16x20in (40x50cm) version of this map.

Where personalisation is available, you can add a short title or dedication, mark one meaningful place, or request one considered visual detail. See personalised map examples.

Every piece is printed to museum-grade archival standards using fade-resistant pigment inks on acid-free matte paper. Choose an unframed map print, framed map or canvas using the finish options above. Framed maps use crystal-clear optical acrylic and arrive ready to hang.

With its rich detail and strong sense of place, this map makes a considered gift for a new home, anniversary, retirement or anyone with a personal connection to the area shown. Still deciding? Explore our collection of rare old and vintage maps to discover another place, period or style.

This map is also available as a float framed canvas, sometimes known as a shadow gap framed canvas or canvas floater. The map is printed on artist's cotton canvas and then stretched over a handmade box frame. We then "float" the canvas inside a wooden frame, which is available in a range of colours (black, dark brown, oak, antique gold and white). This is a wonderful way to present a map without glazing in front. See some examples of float framed canvas maps and explore the differences between my different finishes.

For something truly unique, this map is also available in "Unique 3D", our trademarked process that dramatically transforms the map so that it has a wonderful sense of depth. We combine the original map with detailed topography and elevation data, so that mountains and the terrain really "pop". For more info and examples of 3D maps, check my Unique 3D page.
