August Rockfall on Mount Lidgbird

Dean Hiscox reported new landslip on the east side of Mount Lidgbird in the Middle Cave vicinity on 17 August. The slip has caused significant damage to vegetation down slope of the initial fall zone and is likely to remain unstable for some time. This shows the continuing decay of the island with time. When the island was formed by a volcano 7 million years ago, it was 40 times what we see today, and although rare in human time scale, these events in geological time are frequent. There are no formal walking tracks in this area, and the slip is hidden from view by most people, but on a boat trip around the island it is very visible.
