The Trail Creek Caves are a group of twelve caves found within the Bering Land Bridge National Preserve on the Seward Peninsula of the U.S. state of Alaska. This is a significant archeological site due to the discovery of several artifacts of ancient hunters. These included stone tools and bone fragments dated to 8,500 years or earlier. This location was first excavated in the late 1940s by Danish archeologist Helge Larsen. The caves are located along Trail Creek 65°47′28″N 163°24′58″W / 65.79111°N 163.41611°W / 65.79111; -163.41611 near its mouth at Cottonwood Creek in the Northwest Arctic Borough.^[2]
