Camille Cone is a part of the basaltic lava plateau that surrounds Imuruk Lake on the north central part of Seward Peninsula, Alaska [1]. Hopkins (1963) [1] estimates that Camille Cone is roughly 100 feet high and one mile in diameter. Hornitos are common near the source vent of Camille Cone, which is marked by a smaller welded agglomerate cone that is about 65 feet high [1]. Within this agglomerate cone is a summit crater that is about 60 feet in diameter and filled with loose scoria [1].

Issuing from Camille Cone, and extending 39 km westward from it, is the Camille lava flow [2]. This basaltic pahoehoe lava flow is generally less than 25 feet thick, with initial microrelief features including pressure ridges, hornitos, and collapse depressions visible [1]. However, frost riving has disturbed the surface of the flow along primary fractures that formed during flow emplacement, resulting in individual blocks being tilted from their initial positions and giving the flow an appearance of a jigsaw puzzle with individual pieces spread apart [1].

Camille Cone, and the pahoehoe flow that extends 39 km westward from it, are Late Pleistocene in age [1] [2]. Indeed, Mukasa and others (2007) [3] attempted to date the Camille lava flow via Ar-Ar dating and were unsuccessful due to a lack of appreciable radiogenic Ar. The Camille flow overlies the older Gosling and Imuruk volcanics, whereas the Holocene-aged Lost Jim lava flow overlies the Camille lava flow between Lava Lake and Camille Cone [1] [2].
