Generate for me a description of a spooky scene inside a cave with crystals and a pool.

Only a narrow rim of traversable ground surrounds a massive underground lake of algae-blanketed, foul-smelling water. Wide natural openings in the domed ceiling above permit the warm rays of the sun to permeate the shallow water. White, yellow, and red crystals have formed a thick crust of mineralized rings around the circumfrence of the pool.
