A number of ditches near Silver Star Mountain known as the Indian Pits can be seen on one of the trails, which is known as the Indian Pits Trail #180E. These ditches also occur in other parts of the Columbia River Gorge area. Archaeologists debate the purpose of these pits, though three prominent hypotheses have emerged. One states that the pits were built by Native Americans to seek spiritual visions, while another claims that the pits served as blinds for hunting mountain sheep and goats fleeing cougars or wolves down local talus slopes or other hunters in brush below. The third hypothesis theorizes that the pits were used to store food.
