* In order to focus maintenance and increase cinder availability at Wright and West Triangle pits, beginning in 2026, the Kaibab National Forest will be closing the 0.86-acre public cinder collection area at Moonset Pit. 

The Kaibab National Forest has determined the limited public demand for cinders at Moonset Pit and increased operational complexity and safety risks associated with conflicting uses at the pit justify closure at this time.The total number of personal use cinder permits sold for Moonset Pit has significantly decreased in recent years with only three permits issued between 2023-2025. Cinders from Moonset Pit will continue to be mined and used by Coconino County and the Forest Service to maintain local roads.

Moonset Pit will remain available for the green waste disposal program. 

This change will allow the Forest Service to focus on providing a more positive user experience and sustainable management of cinder resources at Wright and West Triangle pits in alignment with the Forest Service priority of organizational efficiency. The Forest Service is actively working with Coconino County to stockpile material, alleviate hazardous features (such as high walls), and install features to reduce illegal cinder theft at both sites before the 2026 season begins. Through focused resource allocation, staff dedication, and a continued partnership with Coconino County to increase cinder supply and maintain roads, the Forest Service aims to provide a sustainable and cost-effective cinder pit program for the local community for years to come.
