About the map

As a cartographer and admirer of Alaskan landscapes, I have always been fascinated by the intermingled islands, fjords, glaciers, and mountains of Prince William Sound. I started this map in February 2019 and finished it nine months later, working on and off. My aim was to make a physical map showcasing this magnificent place.

Prince William Sound turned out being the most laborious map that I have ever made. The culprit: climate change. Although much of the data that went into making the map was of recent vintage, glaciers in the region have melted noticeably these last few years.

Updating physical features—glaciers, coastlines, rivers, and lakes—from recent satellite images took up ninety percent of my time. Nevertheless, the completed map is only a snapshot in time. Columbia Glacier, for example, lost another one kilometer of its length during the summer of 2019. Much of what the map depicts will be out-of-date again before too long

Enjoy it while it lasts!

Data sources

Shaded relief - National Elevation Dataset, 5-meter IFSAR DEM, collected in 2012 and 2014. Upper elevations derive from the IFSAR DEM downsampled to 15 meters. Lower elevations derive from the same DEM downsampled to 50 meters.

Rock textures - National Elevation Dataset, 5-meter IFSAR downsampled to 15 meters and rendered as texture shading.  Upper elevations only.

Generalized land cover - National Land Cover Dataset, 30-meter resolution, 2011.

Low vegetation




Braided river

Tidal mud flat

Glaciers - National Hydro Dataset supplemented with interpretation from 2018 and 2019 Landsat images taken in late September. Glacier textures derive from a combination of Landsat (everywhere) and texture shading (upper elevations).

Rivers, lakes, and coasts - National Hydrography Dataset supplemented with interpretation from 2018 and 2019 Landsat images. Rivers were manually adjusted to better fit the shaded relief and extended upslope to emerge from glacier snouts. The minor interior channels within braided river extents are a pattern.

Tidal mud flats - 2019 Landsat images.

Labels - US Board on Geographic Names.

Mountain elevations - USGS printed topographic maps (1959-2000) and Wikipedia.

Bathymetry - 2009 NOAA 8/3 arc-second DEM.

Spot depths - 2019 NOAA chart, 1:200,000-scale.

Transportation - 2014 National Transporatation Dataset.

Points of interest - 2007 USDA Chugach National Forest map. The Alaska Department of Natural Resources website was another source. Selected sites shown only on public lands.
