Happy 168th birthday to us! On March 3, 1849, Congress passed a bill creating the Department of the Interior to take charge of the nation’s internal affairs. Interior’s diverse mission – which includes managing America’s vast natural and cultural resources, honoring our tribal relations and supplying the nation with energy – has earned it the nickname “The Department of Everything Else.” Photo of Yosemite National Park by William Woodward (http://ift.tt/18oFfjl).
