Zoom in on Kohala
Viewed from off-shore, the numerous deeply eroded valleys on the north
shore of Kohala volcano are spectacular! In this rare almost cloud-free
scene, we can see Waipio Valley at left and Waimanu Valley at right. At
the back of the valleys, these are more than 800 meters deep. Notice
that even the more gentle slopes of the volcano in between Waipio and
Waimanu is starting to be eroded.
The northern side of Kohala volcano, which is the oldest volcano on the
Big Island, is deeply eroded by numerous large river valleys. Here we see the upper parts of Waimanu Valley (bottom center) and Waipio Valley (left).
