Viewed from the rim of Kilauea Caldera, some of the recent (1971) lava flows show a generally smooth surface at the decameter scale, but many individual pressure ridges at the tens of cm scale. This appears to be shown as a radar-dark surface at L-band. This type of unit is very similar to the floor of Kilauea Iki (Site #23), or to the surface of the September 1982 lava flow (Site #18). It is also very characteristic of the surface of any "trapped" lava flow, such as the ones that formed in pit craters and lava lakes along the Chain of Craters Road. Typically, there is almost no slope on this type of lava flow surface.
From here you can continue on to Site 27 or you can pick another point from the Radar Tourpage.
