The Ice Age
Alaska provided the gateway for many animals into a new world as they followed the Bering Land Bridge from Eurasia to Alaska and then traveled down to populate the Americas. Predators and prey lived side-by-side until changing climates forced many arctic-acclimated species into extinction.
You might be surprised to find that life on the tundra during the ice age was not as barren as it would seem. An abundance of prehistoric animals tramped throughout the landscape at this time and while few survived to walk with modern civilization, some continue to roam the tundra today. The unique features of the surviving mammals like muskox and caribou act as an ancient mirror reflecting the appearance of the curious creatures that did not survive past the Pleistocene.
Ice age animals such as woolly mammoths, steppe bison, American lions, and giant short-faced bears meant survival and life for Paleolithic humans, so it comes as no surprise that much of the prehistoric artwork we find today was dedicated to depicting this main form of sustenance. As we continue to find evidence of prehistoric human and animal life in Bering Land Bridge, we can begin to paint a clearer picture, ourselves, of what the past may have looked like.

A lightning strike ignites a fire in the preserve. The fire burns for a week and then rain puts it out. In about 7 years, a visitor could walk on the burned site having no idea there once was a fire under his or her feet. This speedy site re-vegetation is typical of tundra fire adapted ecosystems.
