“The expedition team navigated through the treacherous karst, relying on their experience to traverse the sinkholes, underground drainage, and caverns that lay ahead.”

“The region's peculiar geology of soft limestone, called karst, has been especially troublesome.”

“The site is a karst depression, or polje, with a natural brook that vanishes into one big and several small ponors.”

“The possibility of hypogenic karstification in deeper environments has been neglected for a long time.”

“The western coast is alluvial or terraced, while the eastern coast is highly indented with pronounced karstification.”

“A process known as karstification has to date created about 3000 circular collapses forming small basins filled with groundwater.”
