 Volunteers are needed at the Granite Mountain Interagency Hotshot Crew Learning and Tribute Center. Volunteers serve primarily as greeters and guides and will conduct some retail transactions. Volunteer shifts are three hours, and all volunteers are subject to a background check and will be trained. The center is located at the Pine Ridge Marketplace, formerly Gateway Mall, and is open Fridays through Sundays. The center is a non-profit all-volunteer organization which houses artifacts, memorabilia, and stories from the 19 heroes who gave their lives on June 30, 2013, while battling the Yarnell Hill Fire.
