As described by the Alaska Volcano Observatory, the Maclaren River Volcanic Field was first recognized by Brueske et al. (2023) and has been further characterized by Bearden (2023). The field, located east of the Maclaren River on either side of the Denali Highway, includes at least three monogenetic volcanoes that date from the last million years. The three identified features lie along a ~20 mile, NNE-SSW line that approximately traces the position of a tear in the Yakutat plate currently subducting under south-central Alaska. The field occurs in an area informally called “the Denali gap,” between the Aleutian and Wrangell arc volcanoes, where only minor volcanism has been identified (see also Buzzard Creek and Jumbo Dome). The lavas from the three cones are basaltic to basaltic andesitic in composition.
