Update on the Developing Halema'uma'u Crater Lake From USGS-HVO (USGS-HVO, PHOTOS BY D. SWANSON) Measured from a vertical distance of about 603 m (1978 ft)—from water surface to the top of the tripod on the crater rim—the dimensions of the crater lake in Halema‘uma‘u were around 71-72 m (233-236 ft) north-south and 157-158 m (515-518 ft) east-west on November 28. The ongoing rise in water level is noticeable when the two photos, taken three days apart, are compared.
