Pyeong Chang 2018 Olympic Winter Games Opening Ceremony Photos

The 2018 Winter Olympics are officially lit. The Olympic flame cauldron is aflame and the 2018 Winter Games in Pyeongchang, South Korea are officially open. Yuna Kim, a South Korean figure skater who won gold at the 2010 Vancouver Olympics, ignited the Olympic cauldron for the Pyeongchang Winter Olympics on Friday night in a bitterly cold opening ceremony that highlighted Korean unity.

The colorful opening ceremony kicked off what will be the biggest Winter Olympic Games in history with more than 2,900 athletes from 92 countries competing -- including one shirtless Tongan cross-country skier, a women's bobsled team from Jamaica and 242 American athletes, the largest delegation in history for the U.S. at a Winter Olympics. Luger Erin Hamlin carried the flag for the United States' delegation -- a day after Shani Davis slammed the coin flip process that picked her.

Vice President Mike Pence, chosen to lead the U.S. delegation, stood as the American contingent of athletes entered the Olympic stadium, but according to the Associated Press, did not stand and applaud when athletes from the two Koreas walked together.
