An Expanding System
After 1916, the NPS expanded with new Eastern parks and a broadened thematic and geographic scope. NPS leaders aimed to reach a wider constituency than possible through Western wilderness parks alone. In 1933, national monuments held by the U.S. Forest Service; the National Capital Parks in Washington, DC; and battlefields, forts, and monuments from the War Department all joined the NPS. The Historic Sites Act of 1935 led to additions of even more historical parks through the mid-century. Park types diversified from ancient structures and battlefields to mounds, forts, missions, and presidential birthplaces. more >>
