| In 2001 a group of Belgian speleologists of the Socotra Karst Project investigated a cave on the island Socotra. |
| That record put the Bulgarian speleologists among the first to reach the lowest point of the planet Earth. |
| The blend of a cave and a church is truly peculiar and fascinating to both speleologists studying caves and archeologists studying all manmade traces. |
| However, speleologists now believe that Mexico's Sistema Cheve, discovered in the late 1980s, extends even deeper than the Lamprechtsofen-Vogelschacht. |
| When speleologists found one such cave in 1977, they named it after Australia's Prime Minister, Malcolm Fraser. |
| The Velebit region is Croatia's largest mountain range, attracting speleologists, botanists and hikers from around the world. |
