The FBI of the National Park Service

The elite special agents assigned to the ISB—the National Park Service’s homegrown equivalent to the FBI—are charged with investigating the most complex crimes committed on the more than 85 million acres of national parks, monuments, historical sites, and preserves administered by the National Park Service, from Alaska’s Noatak National Preserve to Hawai’i Volcanoes National Park.

Three are exactly 33 brave women and men who are part of the Investigative Services Branch, tasked with protecting our national parks.
