In April 1982, a fissure was active on the NE side of Halemaumau that formed both a series of "spatter ramparts " (the person is sitting on one) and a series of small (<1 km long) a'a lava flows. This area is prominent in the radar image as an area of high backscatter.
From here you can continue on to Site 20 or you can pick another point from the Radar Tourpage.
