List of Areas Recommended for Study
In addition to being tasked with conducting authorized studies, US Code (54 USC 100507) also directs the Secretary of the Interior to recommend areas for study for their potential to be included in the National Park System. These reconnaissance surveys are provided directly to the requester upon completion. Requests are made by Congressional members or the Secretary of the Interior. Please email us for further information about specific reconnaissance survey reports.
