It's rare to find Sally Jewell in her Washington, D.C., office.
A little more than a year into her job as Interior Department secretary, she spends much of her time out in the field. It's unavoidable for someone who heads the federal agency that oversees some 400 national parks and nearly 300 million acres of federal lands.
"It's in the job description," she says. "It's also a fun part of the job."
Of late, Jewell has been in the forefront of the administration's efforts to raise awareness of the threat of climate change.
