Got the Rock in time for sunrise. Walked around the base. There's a waterhole out the back, and plenty of rock paintings. I'm not sure what the guides meant by the Aboriginal languages lacking a written form; the signs can be quite sophisticated. If one squints one can (supposedly) find an image of Lasseter's camel dating from the 1920s.
Headed back to Alice Springs, checked into Elkes. The room had a TV, 8 beds, 3 people, a kitchen and a bathroom. Civilisation!
