Today's Lake Rotomahana (white) is much larger than the pre-eruption lake (black outline). With sonar data collected by REMUS vehicles, Vicki Ferrini of Lamont-Doherty Earth Observatory made this color-coded bathymetric map of the lake floor. It revealed a distinctive feature (inset) also seen in pre-1886 photos of the lakeshore. Photos taken by Dan Fornari's camera system showed parts of the Pink Terraces near that feature. Researchers think remnants of the White Terraces lie just north of an area (narrow white patch) they were unable to scan with the two REMUS vehicles. (Map illustration by Amy Caracappa-Qubeck, WHOI.
