These "rocks in the desert" are actually thousands of tall limestone spires, and were formed 25,000 to 30,000 years ago. Apparently after the sea receded from the area it left deposits of shells and coastal winds, then removed the surrounding sand, leaving the pillars exposed. So, yes, they are pretty up there on the "unique" scale of things - are you beginning to see why I might feel a tad guilty?
The tallest of Pinnacles stands between 4-5m, depending on who you ask, and they eerily resemble a field of tombstones or, less disturbingly, large termite mounds.
Attracting almost 200,000 visitors a year, the area has all the benefits of being relatively well-known (maintained roads, informative signs, walking tracks and parking bays), without the hordes of tourists lining up to spoil your photo.
The park itself costs only $11 to get in, and there is a scenic drive marked out through the Pinnacles. There is also a 1.2km loop walk through the park to the Desert View lookout.
The area has been improved recently by the opening of the Pinnacles Desert Discovery Centre, which showcases the Pinnacles' story and provides information on the surrounding flora and fauna.
As I turn to leave the natural spectacle, I can't help but feel like I shouldn't be enjoying the view. But what can you do, you live and learn, right? Just don't mention the Pinnacles to my aunt and uncle - they have since seen photos and are little touchy about the subject.
