Ketchikan B-5 SW is the original title of this richly detailed 1:25,000 topographic sheet, published in 1991 by the U.S. Geological Survey. Set amid the rugged margins of Alaska’s southeast, it captures the Ketchikan area at a moment when science, conservation, and maritime industry intersected. Provisional details signal an edition compiled to deliver current, field-ready information, while a carefully tuned color palette separates elevations and land cover with immediate legibility. Finely drawn contour lines cinch tight across the coastal mountains, telegraphing the abrupt rise from sea level to serrated ridgelines. Water bodies are treated with subtle gradients that distinguish channels, narrows, and lake basins—an elegant cartographic cue to aquatic environments in a land where the sea penetrates deep inland. Political notations, from local delineations to the international line toward British Columbia, complete the geographic portrait.

Created by the USGS—founded in 1879 and long the nation’s definitive cartographer of terrain, resources, and hazards—this map reflects the agency’s late-20th-century mastery of integrated data. The sheet balances ground survey, aerial interpretation, and standardized symbology to produce a product equally at home in the field pack of a ranger and the archive of a researcher. Its “provisional” character conveys urgency and timeliness: timber management, fisheries, transportation planning, and hazard assessment all depended on quick-turn, accurate mapping on Alaska’s fast-changing edge. Coordinate grids, calibrated scale bars, and a disciplined legend reveal a scientific ethos: every symbol is a promise of precision, every color a carefully vetted classification.

The geography rendered here is quintessential Southeast Alaska: a dramatic interface of mountain, forest, and sea. Contours close upon themselves in rhythmic tiers that register the steep, rain-soaked flanks of the Alexander Archipelago. Fjord-like channels and straits thread between forested islands, while perched lakes, hanging valleys, and wetland flats punctuate the slopes and shorelines. Drainages cascade toward tidal water, their sinuous blue traces aligning with notch-like ravines that testify to relentless precipitation and energetic runoff. The cartography makes these processes visible—saddles, cols, and promontories become navigational waypoints; benches and spurs read as safe passage or sudden drop. Gradient tints on water bodies differentiate sheltered narrows from open channels, a quietly sophisticated aid to understanding both hydrology and seamanship.

Human presence appears with a light but incisive touch that makes land use legible at a glance. Urban footprints, working waterfronts, and linked communities are crisply plotted against a backdrop of forest classifications, conveying how settlement clings to narrow coastal benches between tide and mountain. Trails, roads, and utility corridors describe the practical geometry of access in difficult terrain, while boundary symbols trace the administrative fabric of Tongass National Forest districts and other designated reserves. Property lines and political demarcations provide further clarity, situating livelihoods—fisheries, forestry, marine transport—within a regulated landscape. The result is a candid, data-rich view of how people inhabit, traverse, and steward one of North America’s most biodiverse temperate rainforests.

As a historical artifact, the 1991 Ketchikan B-5 SW sheet offers a benchmark for tracking environmental change and policy over time. Its meticulous legend and resolute 1:25,000 scale invite close reading: compare canopy classifications against today’s conservation maps, trace shoreline intricacies against contemporary imagery, or assess infrastructure as it threaded into (or retreated from) the forest. For collectors and scholars alike, its synthesis of terrain, hydrology, and governance exemplifies late-century USGS clarity—informative without clutter, beautiful without affectation. In the tight choreography of lines, hues, and symbols lies a compelling narrative of resilience, resource, and responsibility at the edge of the Pacific, where every contour tells of uplift, weather, and water’s tireless work.

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.
