Uluru is the monolith, and also the name of the area, in the native language. It used to be called Ayer's Rock. The resort is still known as "Ayer's Rock Resort" but the township/area also has a native name, Yulara.

The stony runoff of that ancient river eventually turned into Kata Tjuta (the Olgas) which means "many heads". The sandy part turned into the biggest known monolith in the world. Only about one-seventh of this little "pebble" is on the surface - another 2.5 km stretch out underground. Kata Tjuta is even bigger - some of the "heads" are slabs that extend 6km deep. Standing beside them or in one of their canyons gives you perspective. Seeing a single "pebble" on the horizon that is more than 20 km away is humbling.

After comments from a poet on AllPoetry (Rickets) about getting the bit of the original A/N below about that "pebble" humbling me, and other comments from a second (Robyn Selters,) I changed the last 5 lines of the original to make 2 complete sytanzas instead. The last 5 lines that I've now replaced were:

"Uluru squats in silence,
unstirred, perhaps
too old, while I pace
downwards with my conscience

To gather breakfast from a shop."
