Maui Ground Tour
Stop 5: Napili Bay
[461x420 JPEG]
As one drives north of Lahaina, there are several exposures in the road cuts that give interesting insights to the evolution of West Maui. Here we see (at bottom) a layer of ash that was erupted from a cinder cone at the coast. On top this ash is a younger lava flow, but cutting vertically through both of these units is an intrusive volcanic dike.
From here you can continue on to Stop 6 on the ground, or you can pick another point from the Maui Virtual Field Trip page.
