Here is the original Virtual Cave, devoted to the astounding variety of nature's handiwork found in solution caves, those dissolved out of solid rock by acidic waters. Most solution caves are found in carbonate rocks (limestone, dolomite, or marble) or gypsum. They may occur in sandstones, since carbonates often for the "glue" that holds sandstone together. They can also occur in salt, which dissolves quickly. These pages should provide a glimpse of the amazing variety of these features.
