 Rootless Shield - John Seach

A rootless shield is a pile of lava flows built over a lava tube rather than over a conduit feeding magma from within the earth. Rootless shields along the tube system commonly have a flat top containing a shallow lava pond.
Rootless Shields were common at Kilauea Volcano in 2002.
