On Your Knees Cave
On Your Knees Cave (49-PET-408) is an archaeological site located in southeastern Alaska. Human remains were found at the site in 1996 that dated between 9,730 ±60 and 9,880±50 radiocarbon YBP (Years Before Present) or a calendrical date of 10,300 YBP. In addition to human skeletal remains, stone tools and animal bones were discovered. DNA analyses performed on the human skeletal remains document the presence of mitochondrial haplogroup D which occurs widely in the Americas.〔 Isotopic analysis indicated that the individual had a primarily marine based diet.
== Location ==
On Your Knees Cave is located on the northern tip off Prince of Wales Island within the Tongass National Forest. Its location is approximately one kilometer from the coast and 125 meters above sea level. Originally, the entrance of the cave was obstructed by large rocks and soil that had fallen from the cliff above. However, the cave’s entrance also was heavily covered with vegetation. These factors made the entrance of the cave very difficult to find when the Tongass Cave Project began work near the site. After the obstructions were cleared, the entrance proved to be very small thereby giving the cave its name after the manner one must enter the cave. Once inside the cave, there is a lengthy tunnel with an extremely low ceiling with old bear dens throughout.
