Geo 730: October 12, Day 650: Boiler Bay Midden

Middens are a common sight along the coast; I posted a photo of another one in April of last year. In places where mollusks are abundant, which are particularly obvious along rocky shores, native people would harvest them, carry them back up to the terrace level, and discard the shells into piles that would accumulate for centuries. Soil accumulated around and over these piles, preserving them until erosion exposed them again.
