Glacier park chief says diversity needed

More diversity among park visitors and National Park Service workers will better ensure the nation's most protected landscapes remain that way, Chas Cartwright said.

"If I look at who visits here, let's go with that one first, it is a lot of white people," he said. "We have an international visitation that is fairly substantial, but there are segments of our population that aren't spending much, if any, time in the park, and that really kind of begs the question: Are we relevant to all of America?"
