Figure 2. Stratigraphic section of the Keasey Formation in the vicinity of the Rock Creek seep site, showing position of UCMP localities. Yellow highlighted area above the upper turbidite bed is the equivalent stratigraphic positions of the Main and Second Seep Sites, whereas the minor yellow highlighted area just below the upper turbidite gives the stratigraphic position of small blebby concretions defining the Third Seep Site
