Rootless lava shield W of Pu'u O'o, Hawaii


Brief explanation:

Rootless lava shields are not independent volcanoes, but accumulations of lava flows fed from skylights above lava tubes. They are common features at basaltic shield volcanoes, where the common erupted lava type is very fluid, basaltic lava.
