Safety Equipmment
When treading natural ice, safety has to be prioritized. Every participant has to carry Ice Claws and a Rescue Line.
Ice Poles are needed to interpret the ice. Since they aid in traversing uneven ice it is advantageous for each participant to be equipped with Ice Poles as well.
Most importantly, everyone needs to wear some buoyancy aid. Either a backpack with a waterproof bag or a life jacket.
