From Hildreth and others (2003): "The K-Ar age of 44+/-12 ka measured for the thick andesitic lava flow that forms the crest of the north ridge (fig. 8 [in original text]) supports our stratigraphic and morphologic inference that West Trident is the youngest of the prehistoric centers in the Trident group."
"For West Trident, which banks against Trident I, a 70-m-thick andesitic lava flow capping the north ridge gave a K-Ar age of 44+/-12 ka. An attempt to date the summit lava of West Trident (fig. 8 [in original text]) failed to yield sufficient radiogenic Ar to provide a meaningful age, supporting our field inference that it is still younger than the dated lava flow."
