Larger markers with a crimson double halo are Haunted Locations researched/curated by Where's My Ghost. Smaller markers with a purple single halo are Boo-munity Locations originating from a community Experience. The internal artwork independently indicates ghost or general paranormal activity, UFO or aerial phenomena, or cryptid or creature sightings. Missing or ambiguous categories default to ghost artwork. A separate pale outline marks selection or keyboard focus. Mixed clusters use a neutral style and their labels give the curated and community counts.
