Spruce Tree House Alcove Arch Stabilization

Mesa Verde National Park » Spruce Tree House Alcove Arch Stabilization » Document List

The National Park Service (NPS) is in the planning phases of a proposed project to stabilize the sandstone arch at the front of the Spruce Tree House (STH) cliff dwelling alcove at Mesa Verde National Park (MVNP).

In October 2015, in response to increasing rock falls, the park closed STH. Visitor counts prior to the closure of the site indicated STH was visited by nearly half of all visitors to the park. The combination of continued rock falls from the arch face and underside and the questionable overall arch stability compelled the park to perform analyses of the arch for stability and safety. A thorough analysis has now been conducted to determine the unique engineering issues and requirements needed to complete stabilization design for the arch. Stabilization would not include any alteration of the cliff dwelling structures within the alcove. The stabilization design incorporates features and contractor requirements for protecting natural and cultural resources during construction.

A newsletter that contains information about the preliminary concepts being considered and the environment at MVNP that could be affected by this proposed project may be viewed or downloaded from the Document List or Open For Comment links on the lower left side of this page.

Your feedback is important to the NPS and we hope you will join us in this discussion by submitting ideas and identifying issues of concern. We would like to hear your thoughts on the proposed stabilization design, preliminary alternative concepts, potential issues with park resources and any other ideas you feel are relevant and important. Once we have received and considered your comments, we will move to the next phase, which will include assessing compliance needs under the National Environmental Policy Act (NEPA), National Historic Preservation Act (NHPA) and other environmental regulations.

Thank you for your interest and participation in the development of the Spruce Tree House Alcove Arch Stabilization Project.
