166 Assess a Lava Field

Even if you’re pretty sure it has cooled and hardened, it’s better to detour around a lava field—because if you’re wrong, you’re toast. Literally.

TREAD LIGHTLY If you must cross, try to ensure that the lava has totally hardened. You can’t always tell from looking, because molten lava might be flowing below a thin crust that can fool you. As you make your way forward, probe the ground ahead with a stick.

DO A SNIFF TEST Pay attention to air quality. Sulfur dioxide gases indicate flowing lava beneath you. This gives you two reasons to get away: Not only is the ground unstable, but also that gas is toxic.

HEED YOUR FEET If the soles of your boots start to melt, the flow is too hot to cross. And if the ground feels at all mushy, that means it’s too unstable to cross.
