As I drove down the highway the follows the southwestern coast of Kauai, I noticed all the lava formed domes with basaltic outcrops.
One of the farming areas is shown below.
At the overlook, I noticed these cool eroded basaltic boulders.
Notice the hexagonal shape that is all that remains from the basaltic columns.
The drive was a twisty, turn-filled challenge.
I stopped at multiple overlooks to get some great photos.
Although the lava flow looks fresh, it actually flowed over five million years ago.
Again, the picture below looks sedimentary -- but it shows different lava flows.
