A large pool bubbles in spots, the water is warmed through geothermal
energy from the explosive lava dozens of feet below.  A rather sturdy hut to
the north has a path worn in to the ground leading to the pool, a place to
bathe or perhaps wash clothing.  The water appears to be drinkable but it is
rather warm for most people's tastes.
