Pioneer Seamount is 11.0±0.1 million years old, and is nearly equidimensional with width and length of about 12.8 kilometers. It rises about 1930 meters above the surrounding seafloor to a minimum water depth of 820 meters. It has a volume of about 135 km3. Samples recovered from Pioneer are alkalic basalt, hawaiite, and mugearite. Like samples from Davidson Seamount, all samples are highly vesicular.
