Tsingy - The Amazingly Alien Landscape in Madagascar
"The unusual formations here are a type of karst system, a landscape formed from porous limestone that was dissolved, scoured, and shaped by water. The exact processes that carved such an otherworldly stonescape are complex and rare; only a few similar karst formations exist outside Madagascar. Researchers believe that groundwater infiltrated the great limestone beds and began to dissolve them along joints and faults, creating caves and tunnels. The cavities grew, and eventually their roofs collapsed along the same joints, creating line-straight canyons called grikes, up to 400 feet deep and edged by spires of standing rock. Some grikes are so tight that a human traveler has difficulty passing through them; others are as wide as an avenue."
