beskrivelse:

This is a physical topographic map of Prince William Sound in the Gulf of Alaska, with elevations in feet and depths in fathoms, created by Tom Patterson.

Description on website: "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 Much of what the map depicts will be out-of-date again before too long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!"

Description on map: "This map is for general reference only. Do not use it for marine navigation, aerial navigation, or backcountry travel. Glaciers, rivers, lakes, and coasts continually change position."
