Global Tetrahedron Bouldering

(1) The BLM has amended the Cassia Resource Management Plan (RMP) to permanently close the 400 acres of land it manages in the Castle Rocks Interagency Recreation Area to staging, traditional rock climbing, sport climbing and bouldering, as well as overnight camping and development of new trails. Here is a link to a map that shows the BLM land in yellow. parksandrecreation.idaho.go…

The adjacent Castle Rocks State Park and the National Forest Service land to the north remains OPEN TO CLIMBING,
as does the nearby City of Rocks National Reserve.

(2) HIGHLINING IS PROHIBITED
By the authority of the park manager, Highlining at City of Rocks National Reserve and Castle Rocks State Park is temporarily prohibited as of August 28, 2019.

The park(s) is reviewing highlining activities. Here are Google Drive links to the closure and the updated Code of Regulations for CIRO. drive.google.com/open?id=1y… and drive.google.com/open?id=1Y…

Arrest and/or hefty fines are likely if caught rock climbing with ropes and gear in the BLM land.

Please respect this closure to ensure access to the open climbing at Castle Rocks is not threatened.

The "Final Supplementary Rules for the Castle Rocks Land Use Plan Amendment Area, Idaho" is located in the Federal Registry. This document gives the details on the closure but doesn't provide a map. You can check it out here: federalregister.gov/documen…
