Beyond a certain distance, the lava would have cooled to the point where it could no longer erode the ground, and it would have continued as an ordinary surface lava flow
. The volume eruption rates deduced from the longer sinuous rille channel lengths are very similar to those found for the longest conventional lava flow
units; modeling studies show that the turbulence leading to efficient thermal erosion was probably encouraged by a combination of unusually steep slope and unusually low lava viscosity.
Shield volcanoes occur when very fluid lava flows
long distances on gentle slopes.
A spur road leads to the next point of interest--tree molds--which were formed when molten lava flows
entombed trees and then hardened.
In Hawaii, lava flow

A broad lava flow
crossed onto the property of a Hawaii geothermal power station on Saturday, posing a new hazard as molten rock from the erupting Kilauea volcano bulldozed relentlessly through homes and backyards.
State volcanologists said that there were sporadic and weak lava fountaining, lava flow
