Zugersee — Egg Arth
Arth, Schwyz, Switzerland
UNVERIFIED — Zugersee — Egg Arth is an exact named Swiss freshwater dive site supported by current registry and independent operator/club evidence. The rounded coordinate is a display-only locality marker, not an entry, exit, launch, mooring, wreck position, wall feature, cave entrance or navigation waypoint. Re-check access, closures, navigation rules, weather, lake level, depth and local-operator advice; this is desk research, not field verification.
