DENVER — New satellite imagery released by NASA shows how much Colorado’s landscape has shifted over the years.

One of the pictures shows the Black Forest area before and after the Black Forest Fire.

“It shows that sort of conjunction of wildfire and more people living in a more concentrated space and especially people wanting to live closer to nature,” Colorado state historian Bill Convery said.

Another image shows urban development around Denver International Airport before and after the airport was built.

“Colorado gained more than a million people between 1990 and 2000 and an additional 700,000 between 2000 and 2010,” Convery said.

Then there’s the beetle kill image. It shows how Colorado’s forests have been affected by the pine beetle epidemic.

“The bad news is between 1996 and today, pine beetles killed millions of acres of forest land and it’s going to take a hundred years for that to come back,” Convery said.
