From the World Heritage inscription:
This park, formerly called Uluru (Ayers Rock – Mount Olga) National Park, features spectacular geological formations that dominate the vast red sandy plain of central Australia. Uluru, an immense monolith, and Kata Tjuta, the rock domes located west of Uluru, form part of the traditional belief system of one of the oldest human societies in the world. The traditional owners of Uluru-Kata Tjuta are the Anangu Aboriginal people.
There isn’t much to say about Uluru that I haven’t already said.

Congratulations on your courage in selling everything and taking off to see the world! I don't know if you've been to South America yet, but when you do, I hope you find my blog about Peru to be useful! It's called “Streets of Lima” and can be found here: http://streetsofperu.blogspot.com/
Good luck and keep traveling!
