This map shows an arrangement of rocks.
Close inspection reveals that the rocks form an outline of a box.
Archaeologists studying this area interpret this outline to be the remains of a Native American structure, built sometime between 400 and 600 years ago. One hypothesis for this structure suggests that the rocks may have been part of a small house. The house may have been used for shelter during hunting trips into the mountains. Because the house is not built with good southern exposure and because of its relatively high elevation where snows can accumulate in the winter, some archaeologists think that the house was used only seasonally. Students who visit this ruin are careful to leave the area as they found it.
