In addition to memorializing the life, times, and thinking of Theodore Roosevelt, park managers "conserve unimpaired the scenery and natural and cultural resources and facilitate scientific interests in Theodore Roosevelt National Park" (Theodore Roosevelt National Park, Statement for Management, November 1994). Because the park's land management plan identifies oil and gas development adjacent to the park as the single greatest threat to park resources, this issue is discussed first. Other geologic resource issues that may require management attention follow alphabetically.
