Changing maps

This image shows the elevation profile of the walk across the Portage Lake.

The old, increasingly inaccurate maps Alaskans have used for decades will soon be gone, as our state is being completely remapped. On this next Outdoor Explorer, we’ll learn how the changing climate has made the maps we all use outdated and even unsafe, and the huge effort to fix that. There’s even a role for you, as the government crowd-sources some geographical details. We’re talking maps with the people who use them, make them and study them.
