Travel photographer Anton Petrus, from Kiev, Ukraine, captured rare images of the colorful ice stalactites after crawling deep into the caves of Olkhon Island, which is situated in the middle of what is considered to be the deepest lake in the world, Lake Baikal. During stormy winters, water coats the insides of the caves on the island’s rocky shores, freezing into ice stalactites, which hang from the ceilings. The ice is preserved by the deep, cold caves from January to May for explorers, like Anton Petrus, to discover. Photos: Anton Petrus/Solent News & Photo Agency/VCG
