点评:It was a discovery of the canyons created along the route taken by the Katherine River over the centuries. The boat tour to appreciate the gorge was an excellent experience as this metal bodied flat bottom boat was able to cruise almost silently like it was gliding on still water. Water appeared to be somewhat greenish tinted and rather stagnant than flowing. Operator of the boat gave a running commentary and showed many freshwater crocodiles who have come out perhaps for sun bathing. The specimens we saw were small to medium even though we were told that they could be a decade or more by age. We passed a few beautiful beaches where the sand has settled beautifully sloping towards the river. We were told that these are common egg laying areas of the Crocodiles. While they were predators, they too became probable victims to other predators and even to cannibalistic bigger Crocodiles while they were small.
Due to the dry weather the river has become segmented with each segment formed like a lake, each having a topographical difference but inter connected with a very small over flow to the next. With this phenomenon the first cruise ended at one point and we walked on rocky banks to the next level to board another boat. At this point we were delighted to see many of the aboriginal rock art on a cliffside which were supposed to be several thousand years old. There were hand prints, human and animal figures all in reddish colour. It was interesting to learn how the pre-historic dwellers mixed colours obtaining colours from plant material, crushed rock minerals and then mixing them with clay to use that to paint. Higher the images older they were!
It was a very interesting experience to see the rugged Katherine Gorge with various curious rock formations, deep narrow crevices, caves and deep rock holes. We learnt a lot from the young skipper.

由于天气干燥,河流被分割成几部分,每部分都像湖泊一样,每个部分都有地形差异,但彼此之间有非常小的溢流。由于这种现象,第一次巡游在某个地方结束,我们沿着岩石河岸走到下一层,登上另一艘船。这时,我们很高兴看到悬崖边上有许多土著岩画,据说有几千年的历史了。那里有手印、人类和动物形象,都是红色的。了解史前居民如何混合颜色很有趣,他们从植物材料、粉碎的岩石矿物中获得颜色,然后将它们与粘土混合用于绘画。图像越高,它们就越古老!
看到崎岖的凯瑟琳峡谷,看到各种奇特的岩层、深而窄的裂缝、洞穴和深岩洞,这是一次非常有趣的经历。我们从年轻的船长那里学到了很多东西。
