Many of the dioramas in this hall powerfully represent Theodore Roosevelt’s conservation legacy. “We are not building this country of ours for a day,” he said. “It is to last through the ages.”

During his presidency, Roosevelt set aside five national parks, four game preserves, 51 bird refuges, and 18 national monuments.   He also created or expanded 150 national forests.  Some of the more familiar sites featured in this hall’s dioramas are the Grand Canyon, Yosemite, and Devils Tower, Wyoming.
