Presently, over 400 individuals volunteer as Guardians throughout the event. A dozen Guardians monitor the Temple during each shift, 24 hours a day every day that the Temple is open. Even before the gates open, Guardians stand watch along the Temple perimeter while the Temple Crew completes the build, and will do so again after the Temple has closed on Sunday morning for pre-burn preparations for that night's penultimate event of Burning Man, the Temple burn. A select group of specially trained Guardians will carry offerings from Burners to the Temple, often in memory of those they have lost. The offerings are carefully placed in visible spot and burned with the rest of the memorials for that burn.
