The National Park Service (NPS) has recently completed the Devils Postpile National Monument General Management Plan (GMP) which will provide long-term guidance for management of the monument.

The primary focus of the approved GMP is to emphasize key features with national significance for resource protection and connect visitors with nature and heritage, including traditional park experiences in a natural setting.

Key components of the selected alternative are as follows:

  • Additional emphasis will be placed on connections and partnerships with the Inyo National Forest and the Town of Mammoth Lakes.
  • The monument will continue to be managed as a gateway to a greater wilderness.
  • Natural and cultural resources will continue to receive a high degree of protection with an increased emphasis on providing demonstrations for visitors on a range of resource management techniques to engage visitors in resource management activities and programs such as inventory and monitoring, invasive plant removal, historic preservation, and archeological investigations.
  • Visitor experiences will continue to include a range of low-impact recreational opportunities that have traditionally been available within the monument such as camping, fishing, hiking, sightseeing and wildlife viewing.
  • The monument will explore opportunities for increased trail connections and promote self-discovery and opportunities to connect with nature.
  • Interpretation and education programs and media will emphasize themes related to corridors and connectivity as well as the role of the area as a gateway to a broader wilderness.

Devils Postpile National Monument Seeks Public Input on Draft Accessibility Self-Evaluation and Transition Plan

The National Park Service has prepared a draft report that provides recommendations to improve the accessibility at Devils Postpile National Monument. As part of the planning process, the National Park Service is seeking public comment on the draft plan. The Self-Evaluation and Transition Plan (SETP) is available July 24-September 1 for public review and comment at

An interdisciplinary team, including park and regional staff, identified the key park experiences and park areas to determine which areas would be evaluated for accessibility needs. The team then developed implementation strategies for improving the accessibility at each location. The plan will guide changes to the way existing services, activities, and programs are provided in multiple locations throughout Devils Postpile National Monument by defining what barriers limit accessibility and providing recommendations on how they can be modified or removed to increase accessibility for all users.

Comments may be provided through the above website, or faxed, hand delivered, or mailed to (insert address and fax number here). All comments must be received by September 1, 2017.

Before including your address, phone number, e-mail address, or other personal identifying information in your comment, you should be aware that your entire comment—including your personal identifying information—may be made publicly available at any time. While you can ask us in your comment to withhold your personal identifying information from public review, we cannot guarantee that we will be able to do so.

Your participation is important to our planning process.
