From Riehle and others (1987): "A sample of the basal cone deposits on the north side of the cone yielded a K-Ar age of 0.46k[+/-]0.12 Ma (sample 77, table 3 [in original text]), thus the onset of the cone- building phase of volcanism overlaps or closely succeeds the closing stages of early lava-flow activity."
