The wild north side of Kaua'i, Hawaii is one of sheer cliffs, waterfalls and incredible biodiversity. Combine that with one of the wettest locations on Earth and it is nearly inaccessible to humans.

A Hawaiian hibiscus flower long believed to be extinct was rediscovered during a drone survey. It was in a small colony of three individuals, growing on an inaccessible cliff face.
