4/21.
Arrived ~1pm, sunny, windy, high around 33°C. Hiked the Valley of the Winds (7km) at Kata Tjuta (or Olgas, part of the $25 national park), since Uluru climb was closed due to high wind. 
These giant domes are conglomerate of cobbles and boulders, like sediment, cemented by sandstone. Water tanks are installed along the trail. However, its water tastes chlorine. Hard red earth, low shrubs, some blue and white flowers, birds chirping, a creek flowing. 
Very pleasant, if not for the numerous flies. On the way back, saw 2 errant camels.4/22. Uluru.
Uluru looks like one chocolate truffle dipped in coco powder from afar. The closer it gets, the alien it looks. Coarse grained arkose, punctured by large caves. Sure is impressive. 
The climb was closed due to "forecast rain". Did the short Mala Walk, saw some cave paintings. Mala is hare wallaby. Anangu called themselves the Mala people. This walk follows the ancient route for the ceremony which culminated on top of Uluru.Drove east ~100km to see Mt Conner, another giant monolith now sits on a cattle ranch.
The road stretches ahead endlessly. At the Curtin Springs inn and cattle station, a little cafe serves simple fares at the "BeerAndBullshit Conner", with a slogan:In America, they have Bill Clinton, Bob Hope, Johnny Cash, and Stevie Wonder.
In Australia, we have John Howard, no hope, no cash, no bloody wonder.
The climb was still closed even the sun came out and no sign of rain. Had a lazy afternoon by the pool, due to heat. Walked to the Mutitjulu waterhole at dusk. Only encountered two tourists, yet hundreds of flies. This is my favorite spot in the area. Tried to wait around for Kangaroos. But none came.
4/23. Sunrise at Uluru. Lots of people, and not much color due to the overcast sky. Again the climb was closed.
Only guests can purchase alcoholic drinks in the resort, which operates the only stores in the vicinity. However, those who actually live here are the aboriginals. It's pretty depressing to see some of them waiting at the store front begging for beer from the guests.
