While at Muriella we visited Nourlangi Rock. This is a large rock which seems to appear without the normal gorge around it. The rock has been an Aboriginal shelter for thousands of years. We particularly wanted to visit the Aboriginal shelter which also contains a significant amount of art. We were fortunate to arrive at the main shelter just as the ranger was giving a talk explaining the various paintings and traditions. The interesting fact about the painting of the kangaroo is that this helps to age the painting as it is known that there have not been any kangaroo in Kakadu National Park for over 350 years.
