The Pinnacles Desert is thousands of limestone spires standing in bright yellow sand, most of them knee- to head-high, the tallest around three and a half metres. They run in a loose field across open dune country, close enough together that you walk between them, with no shade anywhere and nothing growing in the sand around their feet. The lime in them began as seashells, ground up on the coast and blown inland as dunes; rainwater carried it down through the sand and cemented it into rock. Why that rock ended up standing in columns is still argued over. The field has also disappeared before: stone tools found among the pillars show people stood here around 6,000 years ago, after which drifting sand buried the whole thing and gave it back only a few centuries ago.
A 4.5-kilometre one-way track threads the field, and the point is to stop, get out and walk. Low sun does the work: early and late, every pillar throws its own long shadow and the sand turns copper, while midday flattens the field into glare. Emus pick their way between the spires, grey kangaroos graze the edges, and in late winter and spring the heath around the sand flowers. Underfoot the sand is soft and deep enough to spill into your shoes. Three or four rows in, the taller columns cut off the sightline back to the track. The Discovery Centre by the entrance closes in the late afternoon, but the desert itself does not. That is when its second show starts. This is one of the darkest skies you can drive to in Western Australia, and for much of the year the bright core of the Milky Way climbs straight over the stones.
