Marine terrace on Santa Rosa Island, California

Marine terrace on Santa Rosa Island

Detailed Description

Foreground shows grass-covered surface of the marine terrace dated to the ~120,000 year high sea stand, Santa Rosa Island, California, and indicates a relatively low uplift rate for this part of the island. Flat surface above this on the skyline is the outer edge of an older terrace, which amino acid ratios suggest is likely of mid-Pleistocene age or older.
