We set out for the Pinnacles, a natural limestone phenomenon about 2 hours north of Perth. These structures are well over 25,000 years old and despite having been researched for 50 years, are still a geological question mark for researchers. Some believe they are petrified trees, and others believe that the structures are left over deposits of seashells, which the wind has exposed over the years.
As we rounded the first corner of the park it left us speechless for a moment, as we took in these intriguing formations, which varied in shapes, sizes, and colors. It didn’t take long before we were too curious to stay in the car, and had to walk about in the thousands of pillar-like rocks.
