Photographer's Note

This an overview of some of the pinnacles in Nambung National Park. This was taken in late afternoon, at the beginning of my visit to the park (late, but not enough to avoid paying the entrance fee). The popcorn clouds were the beginning of an approaching rainstorm. I posted this shot some time ago that shows a close up, that one was taken about 1 hour later. They are NOT termite mounds. Here is the gelogical information that was missing from that posting:

In the Pinnacles Desert, right in the heart of Nambung National Park, thousands of huge limestone pillars rise out of a stark landscape of yellow sand. In places they reach up to three and a half metres tall. Some are jagged, sharp-edged columns, rising to a point; while others resemble tombstones.

The raw material for the limestone of the pinnacles came from sea shells in an earlier epoch rich in marine life. These shells were broken down into lime-rich sands which were brought ashore by waves and then carried inland by the wind to form high, mobile dunes.
