Titled “Ketchikan B-5 SW,” this 1991 provisional topographic map was produced by the U.S. Geological Survey, the federal agency whose maps have long defined the visual language of American landscape science. Issued at the detailed scale of 1:25,000, it presents the intricate coastal world of southeastern Alaska with remarkable clarity: a terrain of steep slopes, broken shorelines, sheltered channels, forested islands, and maritime settlements. The “Provisional” designation gives the map a particular documentary interest, suggesting a working cartographic record assembled from the best available data at the time, pending later refinement. It captures Ketchikan and its surrounding waterways at a moment when the city’s fishing, timber, transport, and tourism economies were closely tied to the geography of the Alexander Archipelago.

Ketchikan appears here not as an isolated town, but as part of a richly interconnected coastal environment. Set along Tongass Narrows, the city occupies a narrow band between sea and mountain, a pattern typical of southeastern Alaska communities where buildable land is scarce and waterways function as highways. The map’s contour lines reveal how quickly the terrain rises from the shore, emphasizing the dramatic compression of human settlement against rugged topography. Nearby Herring Cove, Clover Pass, and smaller settlement areas speak to the importance of sheltered anchorages and navigable channels. In this landscape, every inlet, point, island, and passage matters, shaping routes of travel, patterns of habitation, and the working geography of salmon fishing, logging, and maritime commerce.

The surrounding islands give the map much of its power and complexity. Revilla Island, home to Ketchikan, is shown in relation to Gravina Island, Annette Island, Indian Island, and the broader island-studded coast that defines this part of Alaska. Across the region, coastal lines twist into bays, coves, narrows, and passages, producing a geography that is both beautiful and demanding. Prince of Wales Island and the nearby archipelago form part of a vast maritime frontier where tides, weather, and forested mountains have always influenced movement. The map’s topographic style transforms these features into a precise visual system: contour intervals, shorelines, and hydrographic detail combine to show not merely location, but the physical character of a living coastal landscape.

Tongass National Forest provides an essential backdrop to the map’s historical and environmental significance. As the largest national forest in the United States, the Tongass is a temperate rainforest of immense ecological richness, encompassing old-growth stands, salmon streams, wetlands, alpine ridges, and deeply indented fjords. On this sheet, the forested terrain around Ketchikan is rendered through the disciplined vocabulary of USGS cartography, where elevation, drainage, and shoreline geometry reveal the structure beneath the landscape’s dense vegetation. The topographic character is especially striking: closely spaced contours mark abrupt slopes and mountainous ground, while waterways and coastal margins indicate the region’s dependence on marine access. It is a map of both wilderness and utility, balancing scientific measurement with the practical needs of navigation, land management, and regional planning.

As a 1991 record, “Ketchikan B-5 SW” offers a valuable snapshot of southeastern Alaska before later decades of development, environmental change, and shifting economic priorities. Comparing it with modern mapping would reveal changes in infrastructure, settlement patterns, transportation links, and perhaps even the representation of natural features. Yet its appeal lies not only in what may have changed, but in what endures: the steep meeting of mountain and sea, the sheltered passages of Tongass Narrows and Clover Pass, and the island geography that continues to define Ketchikan’s identity. The map exemplifies late twentieth-century USGS craftsmanship, translating a remote and intricate coastal region into an elegant, information-rich composition. It is both a scientific document and a portrait of place, grounded in the landscape’s enduring drama.

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.

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.
