It forms a prominent exposure in the northwestern Iphigene massif. The peak is named in recognition of Bruce P. Luyendyk, professor (emeritus), University of California,Santa Barbara, who was active in ground- and ocean-based Antarctic research from 1989-2015, significantly advancing the scientific knowledge of the Ross Embayment region of Antarctica. Luyendyk led two on-land expeditions in the Ford Ranges, and was principal investigator for five marine geophysical expeditions in the Ross Sea. In December, 1989, geologists of the UC Santa Barbara FORCE expedition traveled by snowmobile-sledge to Mt. Luyendyk, for the purpose of sampling for rock magnetism, petrology, and geochronology studies. Between 2005 and 2012, geologists from Colorado College, University of Maryland, and Curtin University (Perth) returned to Mt. Luyendyk for structural geology and petrology investigations. GeologyMt. Luyendyk consists of migmatite gneiss and plutonic rocks within the Fosdick Mountains gneiss dome[1]/core complex.[2] The rocks constitute an exposure of the middle crust that was exhumed approximately 100 million years ago, during the Cretaceous Period, by action on the Fosdick Mountains detachment fault.
