| 説明 | About 95% of the cavern's speleothems are dry and inactive today. Crystal Spring Dome, the sparkling wet stalagmite in the picture, may be the largest speleothem still growing. Dripping or flowing water may cause speleothems to grow or to dissolve, depending on chemistry and water volume. Changes may occur too slowly to be noticed during a human lifetime. A drip pool surrounds the base of Crystal Spring Dome.@ Carlsbad Caverns National Park, Whites City, New Mexico |
