Accretionary lava ball
Accretionary lava ball on Mauna Loa. The formation of these is not yet certain however two possible theories are that they form continuously during an 'a'a flow, similar to a snowball or they form from skylights in lave tubes where the piece that falls to create the skylight becomes the nucleus of the accretionary lava ball.
