Oblique view looking north toward Merriam Cone. The distance across the bottom of the image is about 1.8 kilometers (1.1 miles).
Merriam Cone, a symmetrical mound composed of andesite, was
named for a former director of the Carnegie Institution of Washington.
Its surface features and lack of a crater (compare to the Wizard Island cinder cone) indicate that it
formed under water. The andesite composition of Merriam Cone
is similar to that of deeply submerged parts of the Wizard Island
volcano and to the southeast part of the central platform.
