A handout picture taken by the Oman Cave Exploration Team on September 15, 2021, shows one of the team's cavers abseiling down the Barhout well, a sinkhole known as the "Well of Hell" in the desert of Yemen's Al-Mahra province. - A team of Omani cavers has made what is believed to be the first descent to the bottom of the forbidding sinkhole, whose dark, round aperture creates a 30m. (100 feet) wide hole, plunging approximately 112m. (367 feet) below the surface, forming a natural wonder shunned by many locals, who believe it is a prison for genies.
