Spilling Thought: All this week, we are featuring some of the spectacular places in America’s Last Frontier: #Alaska. First up is Bering Land Bridge National Preserve. A visit to #BeringLandBridge can feel like traveling back in time. The Bering Land Bridge provided a pathway for plants, animals and people to cross from the old world to new. #Wildlife like the #muskox remind us of our ancestors and how geography has shaped humankind. These iconic herbivores sport curved horns and can weigh between 400-800 pounds. Although their populations have fluctuated over the last century, today they number around 3,800 in the state of Alaska. #NationalPark Service Photo. by usinterior
