“The woolly mammoths occupied northern Eurasia and northern North America; the Columbian mammoth's range was transcontinental, from Alaska south throughout most of the United States, and went from an elevation of 9,000 feet in the mountains of Utah to sea level in Florida and Mexico. It seems unlikely that such adaptable animals could have been totally wiped out by even the most severe weather conditions.” — Paul S. Martin
