"The reason that I was able to do it is because I was incredibly naive," says Lucas St. Clair. "I had no idea how much work it was going to be, when I started. Not a clue."

The thing Lucas did: work to establish Katahdin Woods and Waters National Monument in the North Woods of Maine.

We started this "Endangered Spaces" series for two reasons. First, we want to take a deeper look at a handful of important, active land battles. Second, and every bit as important, we want to follow the stories of a handful of people who, in their own, quirky ways, have stepped up to protect the threatened spaces they hold dear.

For Lucas, the endangered space wasn't the land he was working to protect, but the communities that surround it.

The comment period for the 27 monuments on Zinke's list ends July 10th. Outdoor Alliance makes it easy to speak out for the places that are important to you.
