Thursday 11 May 2017. Day 15. Drove 160 km to Mataranka. The vegetation along the way gradually increased in size until we eventually we had a few trees with good trunks. We are at Mataranka Homestead with its delightful hot springs surrounded by palms. Quite a large van park which filled up towards dusk. We had two swims in the hot springs. Every night here, there is a live band from 6:30-9pm.

Friday 12 May 2017. Day 16. Rest day at Mataranka. Two dips in the pool which is extremely good. 30.5 million litres of water flow from a spring about 50m upstream from the pool, through the pool and out the otherside. That means 343 litres a second exit the pool. We measured the flow and it is correct. A lot of water. The pool is delightful – lovely, clear, slightly warm water. At Mataranka, we are at 15ºS, ie about the same latitude as Cooktown. At 9pm, Nathan ‘Whippy’ Griggs world champion whip cracker put on an excellent whip cracking show. He holds the Guinness World record of 697 cracks a minute with two whips. https://www.facebook.com/NathanGriggsAU

Saturday 13 May 2017. Day 17. A short 190km drive to Nitmiluk (Katherine Gorge) via Katherine. Nitmiluk is delightful. We are in a shady area near the swimming pool. Blue-faced honeyeaters and silver-crowned friarbirds have entertained us going over the big golden eucalypt flowers just above our van and great bowerbirds have gone over the ground all around us. Quite a lot of red-headed fruit bats in the trees. www.nitmiluktours.com.au

Sunday 14 May 2017. Day  18. Three Gorge Cruise at Nitmiluk (Katherine Gorge) began at 9am and finished just before 1pm. Our guide was Jason who was excellent. We had 24 in the group and had to change boats (with a little walk) between gorges. The water is still 1.5m higher than normal because of the big wet this year. In the wet, the water charges down the gorge forming huge whirlpools where the gorges change direction at right angles. I think a tour in the gorge in the wet has crept onto my bucket list.

The Katherine River runs along a series of huge cracks (that were filled with dolomite) that make a rectilinear network through the hard old sandstone of the Kombolgie Formation. We saw just one freshwater crocodile and very few birds. The bird to the left is a female (because of her brown tail) Blue-winged kookaburra. Very different from the laughing kookaburra of the south. At Nitmiluk, we are just south of 14ºS, ie about the same latitude as just north of Cooktown. This is as far north as we go.

 

 

Grevillea dryandri

Monday 15 May 2017. Day 19. Walked the short loop at Nitmiluk. This initially runs parallel to the river (river left) as the track makes its way up to a couple of stunning lookouts over the river at the beginning of the first gorge. At the top, the track heads inland south away from the river and makes its way across the sandstone plateau that the river cuts through to make the gorges. The vegetation is very interesting (and sparse). Many small grevilleas and acacias. We were out for 3 hours doing the walk and it did get a bit too hot for us. A nice swim on our return. New bird: white-lined honeyeater.

Tuesday 16 May 2017. Day 20. We’ve decided to stay another night at Nitmiluk. It was quite hot yesterday and we needed our little fan last night to get to sleep. We had planned to move on to Edith Falls today but they do not have power and that would be a bit hard for us in this heat. So we will stay another day. I actually like this little campground, shaded and cool around the pool. There is a small colony of red-headed fruit bats just the other side of the pool. They do a fair bit of yelling while they settle down early in the morning (from well before dawn through to after 8pm).

I’m sorry to report that I really do like bats. We have a small, very young fruit bat living alone in the golden-flowered eucalypt trees above our van. From about 3pm it begins going over the blossoms – crawling along along branches cleverly solving the maze of which twig gets it to the next blossom. It is competing with the honeyeaters – that can fly between blossoms and do over the whole tree very quickly. Yesterday, we saw it fly for the first time, which means it can survive when these euc flowers disappear.

At the campground, the bats’ favourite tree to roost in is almost directly over the ablution block. Some campers don’t like the bats and this leads to a daily battle as grounds staff light very smoky fires in 44gal drums to persuade the bats to go elsewhere – which they don’t want to do. Most have returned to the favourite tree by late afternoon. Each morning, the battle recommences.

I have formed a very low opinion of the vast majority of grey nomads. It is a badge of honour to know nothing about anything and to be fearful of everything – people, animals, the land itself, everything. I’m very glad that we did not stay in Katherine itself. I would have lasted just one night with the incessant whinging. Nitmiluk appears to be a bit different. The people who stay at Nitmiluk and who do get out of their vans might be a bit interesting.

Wednesday 17 May 2017. Day 21. Drove south west 220km to Victoria River Roadhouse and campgrounds. Initially the road is through a very uninteresting savannah with small trees spaced about 30m apart. Then suddenly we began the gradual descent (over about 80km) into the Victoria River which has quite marked cliffs of red rock. The reddest rock that we have seen. Victoria River campground is friendly, well maintained, grassed, flat and with a few trees. We were first here and got the best shade. A few mozies at night which drove us inside at dusk. Same birds here as at Nitmiluk minus the silver-crowned friarbirds. No bats. We were planning to spend a couple of nights here but it is just too hot. No phone service and so no internet connection.

At Victoria River, we are at 15º37’S ie same latitude as just south of Cooktown. The Victoria River catchment is huge – 87,900km². This place sometimes gets a metre of rain at a time, which turns those square kilometres into 87.9million cubic metres (or 175.8 sydharbs) of water that wants to get to the sea in 5 minutes. It is all gone in a few days and the country nice and dry for the rest of the year. That is a f**king lot of water. All at 35ºC.

That ends week 3. Twenty-one days on the road. Since Wagga, we have driven 3,842kms and are just less than 300km short of the WA border. Only about 500km for the week. That is more like it. The high temperature has prevented us from free camping at all. Without the electric fan we would be struggling.

Shield Shrimp

When it rains across Australia’s vast inland region, temporary pools crop up all over the arid ground, giving life to a strange desert crustacean known as the shield shrimp (Triops australiensis).

Named after the formidable carapace that shields its head and upper body, T. australiensis can grow up to 7.6 cm long, and it uses its long, segmented tail and mass of 60 or so legs to propel itself through shallow water.

It also breathes through these legs – its sub-class Branchiopoda means ‘gill-legged’ – and in the females these legs bear ovisacs for carrying their tiny eggs.

Acacia peuce

A rare and endangered plant. The tree grows up to 15 to 18 metres (49 to 59 ft) high, with short horizontal branches and pendulous branchlets covered in needle-like phyllodes adapted for the arid dry climate. It has a distinctive habit more similar to a sheoak or a conifer.

Although speculated to have been widespread across central Australia during wetter climates 400,000 years ago, the population is now mostly restricted to three sites, separated by the encroaching Simpson Desert. In the Northern Territory, the species is restricted to the Mac Clark (Acacia peuce) Conservation Reserve which is surrounded by a pastoral lease, Andado Station. The other two sites are near Boulia and Birdsville in Queensland. The tree is found in open arid plains that usually receive less than 150 millimetres (5.9 in) of rain per annum. They grow on shallow sand aprons overlaying gibber or clay slopes and plains and between longitudinal dunes or on alluvial flats between ephemeral watercourses.

 

Owen Springs Reserve on Hugh River

Owen Springs was a station on the Hugh River. The Hugh River flows into the Finke (when it actually flows). Both cut through the Western MacDonnell Ranges. The image above shows Owen Springs Reserve as a dot at lower right. The river it is next to is the Hugh. Hermannsburg, our next town, is near middle left edge. Hermannsburg is almost on the Finke River. You can see both Hugh and Finke Rivers cutting through sections of MacDonnell Ranges.

Palm Valley

Palm Valley is within the Finke Gorge National Park southwest of Alice Springs. Palm Valley has a smallish population of Red Cabbage Palms (Livistona mariae). The nearest related species is 850 kilometres away in Katherine NT. The average rainfall for Palm Valley is just 200 mm per year. Small pockets of semi-permanent spring-fed pools allow the unique flora and fauna (desert fish, shield shrimps tadpoles and frogs) to survive.

It had been assumed that the cabbage palms were remnants of a prehistoric time when the climate supported tropical rainforest in what is now the arid inland of Australia. Genetic analysis published in 2012 determined that Livistona mariae at Palm Valley is actually the same species as Livistona rigida from samples collected near Katherine and Mount Isa, both around 1,000 kilometres (620 mi) away. It is now thought that aboriginal people brought the palms to here from Mataranka.

Mound Springs

Mound Springs occur around the Western edge of the Great Artesian Basin and represent a natural discharge of Artesian water that was captured many hundreds of kilometers away from rain falling along the Great Dividing Range and New Guinea. This article provides details. Dalhousie is an excellent example of a mound spring.
