Viewed from the crater rim at Pu'u Puai (the vent for the 1959 eruption), one can see remnants of something similar to "lava icebergs" which were floating on the lake surface (or grounded on the crater wall) that then became trapped in the cooling lake. These blocks are 3 - 5 meters thick, and show up clearly as very bright targets in the radar image. The white line running through the image from right to left is a path (see Site #24 ) used by tourists to visit the vent of the eruption.
From here you can continue on to Site 23 or you can pick another point from the Radar Tourpage.
