| Location description: |
Anchor Point section. Wave-cut bluff along the Cook Inlet shore of the lower Kenai Peninsula, approximately 2 km south of the mouth of the Anchor River. The bluff is 270 cm thick and and consists of tephra and loose to dense fibrous sphagnum peat becoming denser with depth to the basal contact with the underlying light-grey, massive silt with medium-grained sand lenses. The basal contact between the peat and silt is at approximately 3.5 m above sea level, with the massive silt continuing downward to an undetermined depth. The silt does contain a 2- to 3-cm-thick lens of decomposed organic material 20 cm below the contact with the overlying peat. Twenty-one tephra or possible tephra were sampled from this section, although the section also contained stringers of thin (<1 mm thick) tephra, both continuous and discontinuous, that were not described or sampled. Four of the twenty-one tephra were sampled from the upper 10 cm at the section, however, because they were <1 mm thick, they were not considered for analyses. Two of the remaining 16 samples were determined not to be tephra, and one did not have enough glass to be analyzed via EPMA (97AP-F). Coordinates provided as decimal/degrees/seconds and converted to decimal degrees. Datum not specified, assumed to be NAD83. |
