Wrangel Island lies astride the 180° meridian. The International Date Line is displaced eastwards at this latitude to avoid the island as well as the Chukchi Peninsula on the Russian mainland. The closest land to Wrangel Island is tiny and rocky Herald Island located 60 km (37 mi) to the east. The distance to the closest point on the mainland is 140 km (87 mi).
