LAKE BAIKAL, Russia — The Lake Baikal ice was the real star even among a gathering of some of Russia’s hockey greats. The ice in the Siberian UNESCO World Heritage site is famously clear, with cracks weaving through the deep blue depths like white veins. Small air bubbles below its surface are visible. During Russia’s winter months, cars can safely drive on it for hours.
