Detailed Description
During their field work today, HVO geologists tested a new range finder to determine the distance to and size of the water ponds at the bottom of Halema‘uma‘u. Range finder measurements indicated that the water is about 663 m (2175 ft) below the tripod they had set up on the crater rim for observations. USGS photo by C. Parcheta, 08/03/2019.
