Caves potential tourist sites

A geology professor has said that caves across the Kingdom’s deserts require study in order to be exploited for tourism. King Saud University professor Abdulaziz bin La’boun was quoted by the Saudi Press Agency as saying caves are rare natural sights and that they qualify as tourist destinations.
The "Dahl Alakdhar," or green cave, located in the Summan area northeast of the Kingdom, is one of the most beautiful sights given it colorful stalactites that are not found in any other cave in the country, said the professor, who gave the cave its name.
“The algae and vegetation that has grown on its outer walls indicate that it contains water in the form of steam,” he said.
A team of photographers visited the area to explore the caves. They stopped at the entrance, which bore a distinctive look among thousands of caves in the area.
“Entering the cave was risky because of the presence of toxic gases and a lack of oxygen, not to mention the possibility of rock slides and accidents caused by slippery rocks,” said La’boun.
The team descended into the cave through an almost vertical passage with sharp edges.
