Point Grenville is located in the Olympic Coast Region of Washington and is accessed by permission of the Quinault Indian Nation. This gently sloping site consists of extremely uneven terrain, containing many deep cracks and folds.

Point Grenville is dominated by consolidated bedrock, and the area surrounding the site is comprised of a mixture of consolidated bedrock, boulder fields, and sandy beach. The primary coastal orientation of this site is north.
