Beschreibung
Two Holocene tuff rings form craters 300 and 66 m wide near the headwaters of Buzzard Creek at the northern foot of the central Alaska Range NE of the town of Healy along the Parks Highway. The total volume of ejecta, most of which is accessory material, probably does not exceed 0.001 cu km. The ejecta overlies young glacial terraces that correlate with a glacial stage that ended about 10,000 years ago, and radiocarbon dates give an age for the eruption that formed the tuff rings of about 3000 years. This minor volcanic feature lies along trend with the Aleutian arc, but is located 320 km NE of its nearest Holocene neighbor, Hayes volcano and lies directly over the northernmost corner of the subducting Pacific Plate.---
