In upcoming Minecraft updates, deep glacial caverns generate in cold mountain biomes beneath permafrost layers. Packed ice and high-friction blue ice form natural slip-tunnels, while fragile hanging icicles pose overhead stalactite hazards.
Place lanterns or torches near packed ice to observe thermal dissipation. Thermal simulation calculates Manhattan radius radiant heat, thawing crystalline blue ice back into flowing subterranean aquifers and dislodging icicles.
