Where the wild things are

Cool little story in the New York Times this morning on a mapping project to show where the truly wild places are now. It comes with a popup map of the continental U.S. showing the few places left here.
The work was compiled by the Wildlife Conservation Society and the Center for International Earth Science Information at Columbia. Their websites have similar maps for the entire world. As you might guess, the truly wild places tend to be a little on the hot or cold side. Think Canada, Siberia and the Sahara.
In the U.S., four of the most "untouched by human hands" areas are....
-The Jarbridge Wilderness of Nevada
-The Central Idaho Wilderness
-The Endless Mountains and Grand Canyon of Pennsylvania (yes, Pennsylvania)
-and, the Texas Grasslands along the Gulf Coast.
