Operational incident logger, remote circular grid coordinate resolver, evidence chain-of-custody manager, and medevac flight window auditor for off-grid gatherings.
Standard operating procedure for remote, multi-jurisdiction environments (Federal BLM, County Sheriff, Event Medical Staff). Ensure scene isolation prior to non-lifesaving entry.

Flight safety rule: Whiteout dust storms ground all rotary flights on the desert playa floor. During sustained whiteouts (>45kt winds), all patient transfers default to 4x4 heavy tracked ground ambulance via Highway 34 bypass.
Mass gathering events on federal public lands (such as the Black Rock Desert playa) require immediate synchronization between event safety rangers, county sheriffs (criminal investigations), BLM federal officers (public land authority), and regional coroners.
Temporary remote cities use clock dials (2:00 to 10:00) and concentric lettered avenues (Esplanade through K) to pinpoint locations. The interactive engine converts radial polar offsets into statutory distances and GPS approximations.
Desert haboobs and high-particulate whiteouts immediately trigger LZ closure under FAA Part 135 HEMS rules. When the aeromedical window shuts, incident command must immediately mobilize ground transport assets.
