The toe of the 1972 lava flow ends on grassy slopes on the southern flank of MacKenney cone.  Broken slabs mark the flow front.  The rock hammer at the upper right provides scale next to a spectacular grooved lava surface on the top of the flow front that formed when still-fluid lava was squeezed through an irregular crack in previously solidified crust.
