End of Makena Road, Maui

Drive to the end of Makena Road in Maui, and the terrain becomes very different.
 
No, Haleakala has not gone active - those are regular clouds. The foreground is a mix of coral pieces and lava. Together, it all makes a colorful picture.
 
Note that few subjects absorb light better than volcanic rock. This stuff eats light - like a light sponge.
