Making a National Park Service (NPS) visitor map of a large, famous park such as Glacier Bay involves careful planning and many people. Preliminary work on the Glacier Bay map required a site visit to Alaska, consultations with park staff, and observing visitors using maps on board a cruise ship. The paper examines various mountain-mapping challenges, including shaded relief, landcover, glaciers, fjord bathymetry, braided rivers, and place names. The paper then ties these strands together by discussing the design of the final brochure map.
