Whether, in the days of its use, anyone viewed the Bering Land Bridge as a landmark is doubtful. It wasn’t a bridge at all but rather a 1,000-mile-wide connector between Asia and North America. Sea level fell when Ice Age glaciers took up vast quantities of water and rose when those glaciers melted. In turn, the bridge appeared and disappeared. People lived on it and moved east across it as conditions permitted. Some continued south as the continental glaciers melted. Genetic evidence indicates that these Asian immigrants were the true first Americans. The bridge is still there, beneath the relatively shallow waters of the Bering Sea. The landmark means more to modern people as we ponder our heritage, study our maps, and consider the mere 50-mile separation between Asia and North America. The preserve, not precisely on the tip of Alaska’s Seward Peninsula, is a larger-than-Yellowstone chunk of pure roadless arctic wildness
