Flowing lava leaves its mark in many ways. The simplest
of these are flow lines, etched into the walls of the cave or floor
of the cave.. The lower photo shows a phenomenon sometimes seen in places
where two major conduits converge, leaving a v-shaped point aimed in
the direction of the flow at the head of the passage wall that divides
them. These are called “ship’s prows” for their resemblance to such
a feature. The one below has an unusual hanging “mini-prow” suspended
above and pointing the same direction as the prow beneath it: downflow. |
