Lanikai
I grew up in Lanikai, on Windward Oahu, and woke up every morning to a spectacular view of the Mokulua Islands.
Twin Islands are part of a dike complex, as are the hills behind Lanikai, and Olomana mountain. When the Koolau volcano eroded, much of the resistant dike rock was left behind.

Above: Beach on the larger Mokulua Island features white sand, black basalt rocks, and elevated coral reef from a higher stand of the sea.
Above: Mokulua Islands exist because they are riddled with dikes. The softer adjacent material eroded away, leaving the linear dike features exposed.
