chasing down prey. They hunted by ambushing animals like deer, camels, ground sloths, bison, and young mammoths. Saber-toothed cats, or tigers, are known for their oversized canine teeth, which could reach seven to ten inches (17–20 cm) in length. Standing around 3 feet (one meter) tall and weighing up to 750 pounds (340 kg), saber-toothed cats had a bulky, muscular build that allowed them to subdue large prey, like sloths, bison, and young mammoths. Some fossil evidence suggests that they may have hunted in packs. Herbivores Columbian mammoths stood up to 14 feet (over four meters) tall at the shoulder and weighed 18,000–22,000 pounds (8,000–10,000 kilograms). They had large tusks and ridged teeth for eating plants like modern elephants. These giant herbivores probably did not have much hair, unlike the woolly mammoths that evolved in colder regions. Columbian mammoths inhabited a range from Canada to Nicaragua and Honduras. Camels are commonly associated with Africa, though they originated in North America. The ancient western camel probably resembled modern, one-humped dromedary camels, but with longer legs, standing up to seven feet (over two meters) tall at the shoulder. The camels were opportunistic herbivores, grazing over large ranges, and leaving distinctive footprints. Ground sloths are the ancient relatives of modern tree sloths, armadillos, and anteaters. The Harlan's ground sloth dwarfed modern relatives, standing 10 feet (three meters) tall when upright and weighing over a ton (about 2,200–2,400 pounds or 1000–1090 kilograms). These giant herbivores had a slow, waddling walk and left kidney-bean shaped footprints, created as their back feet rotated inwards while walking. Some ground sloth prints appear bipedal, possibly caused by the large hind feet covering the tracks of the smaller front feet. Such tracks have sometimes been mistaken for the tracks of a giant human. Visitation White Sands National Park is the most visited NPS site in New Mexico, with about 600,000 visitors each year. In year two of the pandemic, White Sands National Park saw more than 780,000 visitors from both locals and visitors. Many visitors arrive during the warmer months from March through August, but sledders and photographers can be seen throughout the dunes year round. March and July are the two busiest months with more than 60,000 visitors each, or about 2,000 per day, while November through February have the fewest visitors with less than 30,000 each month, or fewer than 1,000 per day.
