How often do tourists break these distance rules?
"Often," says Owen. "Very often."
In fact, she adds: "We are currently in the middle of a management nightmare."
A cow moose, Owen says, recently gave birth to twin calves. For reasons that might be based on food sources, or protection from predators, the cow and her calves are living inside the most popular campground in Denali, at the park's entrance.
The moose is extremely agitated, says Owen. "We've had two fairly serious injuries and I've lost track of the number of charges."
However, Owen says, despite the plethora of signs around the campground telling people to not disturb the moose, the three wildlife technicians rotating in and out of the campground - which is host to 150 sites - other support staff spreading the word about the moose, and a press release calling attention to the situation, tourists just do not seem to listen.
"I'm at my wits end," says Owen.
"It seems to me that people fall on either one side of the line or the other," she says, when describing the kinds of people who follow the park's rules - or do not. "They either get it, or they don't. Though even our most conscientious tourists are problematic," she adds.
