Walking on an industrial site – posting 5 of 5

Eventually we walked onto the Nyrstar wharf, after sometimes successfully dodging water sprays to keep the dust down. Here I was able to look upstream and enjoy the expanse of the Derwent River, and to recognise the Bowen Bridge and Mount Direction in the distance.  20170227_111100.jpg

We passed equipment such as the dust measurer shown below.

20170227_114227.jpg

At the western end I was able to look past the big sheds of the INCAT boat building industry over Prince of Wales Bay and see Technopark perched on top of Dowsing Point.

Looking back downstream the river and landscape appeared as follows:       20170227_111525.jpg

I also enjoyed walking through parts of the large industrial site for the geometric shapes of the structures and for the various vintages of buildings. Most of all, similarly to my feelings about the Hydro Tasmania structures in the upper Derwent Valley and beyond, I admired the pioneering and massive engineering works that created the manmade parts of the site. 20170227_112925.jpg

20170227_113459.jpgI was surprised at the extent of chemical hazards which need good management; associated with the zinc smelting process are dangerous chemicals such as mercury, cadmium and lead. During the walk I learnt a great deal about the attitude of the business towards instituting and maintaining good environmental practices. In addition, I was shown revegetated expanses and different buildings which prioritise care for the environment and make it a reality. Seeing and experiencing all of this was much more than I expected, and I remain immensely grateful for the time and interest given by my excellent host Todd.

In a special showcase at Nyrstar’s Reception, plaques and various awards are clustered together. One example, a National River Prize, was presented by the International River Foundation in 2010 to the Derwent Estuary Program,  of which Nyrstar is a founding member.  A list of the Australian winners that year can be read here and if you refer to page eight, more information about Nyrstar and the Derwent estuary is available. My photo below includes that framed paper award with another sculptural award sitting in front.

Overall, I was delighted to be able to fill a gap in my walk along the Derwent River, on this private property.  I am indebted to friend Clinton for his connections with Nyrstar that helped to make the walk a reality. Especial thanks to my thoughtful host Todd, and to Nyrstar.

Walking on an industrial site – posting 1 of 5

 

This seems an appropriate time to add in the stories of my walk along the water edge of one of Greater Hobart Area’s iconic industrial estates in its 100th year of operation.  This series of postings records the morning when I was privileged to be given permission to walk on some of Nyrstar’s property.  But first – a reminder of what the site looks like from a distance; from other vantage points during my walk along the Derwent.

For example, my blog posting Either side of Bowen bridge – posting 5 of 9 included a photo looking at Nyrstar from Dowsing Point and across Prince of Wales Bay.  Refer also to my postings On through the East Risdon State Reserve along the Derwent River and Along the northern side of Shag Bay and onwards along the Derwent River for additional photos of Nyrstar. These latter two postings were made after my walk through the East Risdon State Reserve on the eastern shore across the Derwent River from Nyrstar on the western shore.

Colloquially known as ‘the zinc works’ or the ‘Risdon works’, Nyrstar’s operation centres around converting raw materials into zinc metal.  More can be read here.

Special permission was required to walk on this land and I needed to agree to particular conditions before I could proceed. The extensive site holds many dangers of physical, chemical, electrical, mechanical and liquid kinds and legislation and internal procedures regulate entry and access. This is not a public access walk.  After arrival at the Reception  office on-site,  I submitted to a health and safety induction process, donned a high-vis vest and other safety gear (including designated boots), and accepted that I must be accompanied by a staff member at all times. My host and guide was a senior manager whose understanding, knowledge and passion  for the environment had to be second to none.  I could not have been more fortunate. And he also loved the Derwent River and told me how he jumped into his kayak to explore the river whenever he could find a moment (no – not while he is at work!).

The day of our walk was gloriously sunny with hardly a puff of white marking the sky; exceptional walking weather where every detail is clear.

A considerable portion of the Nyrstar industrial buildings edge the Derwent River as shown in the Google map excerpt below.

Nyrstar’s property extends into New Town Bay. I expected only to walk on and next to the rocky shore along the lines I marked on the Google map below.  Future postings will reveal whether I actually walked further.

I am so very grateful for the support and interest and assistance which Nyrstar provided to ensure that my walk along the Derwent River was complete.  Staff all over the site could not have been more pleasant.

 

Either side of Bowen bridge and Bags on the fence – posting 9 of 9

Because of the isolation of the track and the distance from the residential areas, I find it difficult to believe that people walk here and bring their dogs on a lead.  But what are the tied up plastic bags on the fence if they are not collections of doggy poop.  Any ideas?  They cannot be lunchbags used by Technopark staff because they are on the outside of Technopark’s most outside fence.  Strange. Colourful.  Unnecessary additional reminders of man’s encroachment on natural areas.

Either side of Bowen bridge – posting 8 of 9

I continued along this rocky edge of Prince of Wales Bay a few metres away from the main run of the Derwent River, until it was clear that full access around the inlet at water level would not be possible.

20170125_110248

Eventually I came up from the shore and walked through the grass with pounding feet hoping the vibration would deter any snakes.

20170125_110615

I noted that a creative soul had walked this track.  Obviously inspired by the movement of the firm strands of tall grass, on two occasions in different places, a person has plaited stalks together to offer markers of mankind in the neighbourhood, or so it seemed to me.

Either side of Bowen bridge – posting 7 of 9

Quite quickly I reached the point directly opposite INCAT, while walking around Dowsing Point. I loved the  slabs of rock making up the shore edge. In particular I loved the fluorescent lime green moss/sea vegetation where exposed by the low tide.

The various high tidal marks on a pebble beach left parallel rows of stones and empty oyster shells.

20170125_110221.jpg

20170125_110202.jpgUnderwater, and still attached to rocks, were the bottom half of oyster shells minus their tasty flesh.

Did I have company? – posting 6 of 9

On both sides of the Bowen Bridge lots of dry tall yellow grasses and other scrubby undergrowth grew next to the path. I was the only person around and the track appeared to be used rarely. The area was isolated; the closest residential area was over one kilometre away and I suspect that locals would seldom walk here. With the heat of the day and the nearness of the river, I was alert for the slither of snakes heading down for a desperate drink. However, I feel sure they would be deranged if they drank salty water  –  the Derwent is tidal at this point. Nevertheless I  did not want to step on or corner one – all Tasmanian snakes are venomous.

Strangely, not only did I not see a snake but I also did not see a water bird.  Thankfully there were a few chattering birds in the casuarina and eucalypt trees to keep me company.

Earlier in the day when I was walking around the Technopark fence line downhill nearest the Derwent River,  I had watched dozens of brightly blue and red coloured beetles- I haven’t seen these before, and a website for identifying Tasmanian beetles does not include this one.  Anybody any ideas?

20170125_084516.jpg

20170125_084523.jpg

The experience was very pleasant and I would be very happy to wander this way again.

Word of caution for others who might follow in my footsteps: the seedpods of the casuarina were liberally sprinkled along the pathway and in the light dappled by the trees, full concentration was required so that I didn’t roll on them – a sprained ankle or a fall down the slope were just two possible consequences if I did not watch where I was going.

Once under the Bowen Bridge I could see a track continued in the easterly direction, and skirted around the bottom of Technopark.

20170125_104953.jpg

20170125_105002.jpg

20170125_105044.jpg

100 metres along this track I spotted the only sign of bureaucracy.

20170125_105314.jpg

I imagined I might surprise a fisherman at the end of the track or detect one who had made his or her way from the track to the water’s edge and was partially hidden by the bush. But I never did. I never saw anyone.

As I continued walking I spotted the township of Risdon across the river.

20170125_105336.jpg

20170125_105554.jpg

And then the large industrial plant of Nystar came into view.

20170125_105544.jpg

Most prominently, the gaping ‘mouths’ of the  boat building company INCAT stood across the inlet of the Derwent River (Prince of Wales Bay) from Dowsing Point.

Either side of Bowen bridge – posting 4 of 9

I decided to walk from the Bowen Bridge around Dowsing Point towards the Derwent Entertainment Centre on the Glenorchy side of the bridge.  A faint track showing occasional foot traffic looked promising and became my guide.

20170125_095351.jpg

Early in the walk along this track, easy views to and access to the water were not possible although as time passed the river came into constant view. 20170125_095427.jpg

20170125_095500.jpg

Then the pebbled and rocky shore appeared.

20170125_095708.jpg

20170125_095446.jpg

I was delighted when I came across a slight semblance of a track down to the river’s edge.  Soon I was on the shore and walking that rocky ‘beach’.  The wind was fierce but not cold. My sunhat had no chance of staying attached to my head. I lathered on the sunscreen hoping for wind protection. But it was fresh and invigorating. The air was alive and so I felt even more alive. And so pleased that my return visit to Dowsing Point had been able to bring me down to the water of the Derwent River.

20170125_095949.jpg

20170125_100222.jpg

20170125_101115.jpg

Clearly native oysters grow on the rocks near the shore.  The whitening shells of long dead oysters were thrown up at the high tide level.  I was surprised not to see any Australian Pied Oystercatcher birds looking for a meal.

20170125_100126.jpg

I continued walking around the contours of Dowsing Point, thankful that the tide was out and the shore was wide enough, dry enough and had no insurmountable obstacles. But beneath the northern section of the fenced-in defence forces precinct suddenly the ground became marshy and a trickle of water in a swampy like environment emptied into the Derwent. I did not believe this was passable.  Perhaps if the tide had been lower and if I was wearing gumboots, I might have continued.  On another day, this most likely could be a doable section and one I could tackle from the Derwent Entertainment Centre end of the walk.

After searching unsuccessfully for alternatives, eventually I retraced my steps, and climbed a grassy hill for another view of the obstacle – which looks benign in the photo below.

20170125_103014.jpg

I have walked along the Dowsing Point suburban streets with paddocks at their ends that extend to the shoreline shown above, such as Park Road and Dwyer Place. Unfortunately high fences,  locked gates and dead ends prevent access to this defence forces land.  Trespassers Prosecuted signs were a deterrent.  20170125_091847.jpg

20170125_092014.jpg

20170125_092225.jpg

From the obstacle preventing my continued shore walking,  I turned back and walked towards the Bowen Bridge.  Eventually I left the beach after reconnecting with the hillside track used earlier.

20170125_100021.jpg

20170125_100230.jpg

Occasionally, next to the faint track through the grass, someone had placed track markers – coloured rectangles on posts. Very thoughtful.  On the way back I found a wonderful confusion of markers; just as we know some mailbox catalogue deliverers dump a pile of undelivered catalogues in drains or over someone’s fence, it seemed the person placing the track markers dumped his/her extras. So there I was, faced with an amusing mini-forest of markers all pointing nowhere and signifying nothing.

20170125_103746.jpg

The markers of mankind are always there to be found, and to be puzzled over by those without experience.  But I found my way and soon returned to the Bridge.

As I left Technopark I had a view of a new aspect of the Derwent River.

The Derwent River flows into Prince of Wales Bay and consists of tiny inlets including one at the bottom of the Dowsing Point hill.  I noted there were  no opportunities to walk next to the edge in the bay below – either vegetation hung over the water or private jetties and businesses crowded the edge.

20170125_090417.jpg

20170125_090358.jpg

20170125_090520.jpg

20170125_090532.jpg During the many vehicular crossings of the Bowen Bridge that I have made, I could never see where it would be possible to climb down and be under the bridge. Nevertheless I felt there must be a way.

I walked along a path from the Australian Army Derwent Barracks on Goodwood Road that leads to and crosses the bridge.  The quality of the path is variable and I suspect it is not much used. One cyclist passed me on my walk to the bridge and no-one was around during my return trip.

20170125_094433.jpg

20170125_094721.jpg

20170125_111833.jpg

At the bridge I noticed the large bronze plaque marking the official opening of the bridge – heavily graffitied.

20170125_104645.jpg

But was there a path to the river below?  The absence of signage was not encouraging.

Stage 8 of my walk from the mouth the source of the Derwent River took me under the Bowen Bridge on the eastern shore, and during Stage 10 I walked past the Bridge at Dowsing Point on the western shore after deciding to walk to the mouth on both sides of the river. However, when on the western shore I could not easily see a way to stick by the river edge at Dowsing Point, and since that day promised to be a long one I took the easy option and followed the streets which cut across the Point. I always felt that I hadn’t been quite honest in taking this approach and that I needed to return and be serious about walking the Derwent edge to the extent it was possible.

So return I did, and this series of postings records that visit.

As usual within the Greater Hobart Area, I took a Metro bus which dropped me off one morning within the Technopark precinct at Dowsing Point on the Hobart side of the Bowen Bridge. Technopark is a state government initiative started over 15 years ago with the aim of providing support and encouragement for small businesses and creative individuals with technological related ideas that could be developed into significant money earners for Tasmania’s productive growth. It’s brief has expanded since its inception.

By leaving the bus at the turning circle within Technopark I hoped there might be ways to walk to the river edge and then continue around Dowsing Point.  Until I looked around that day, I had not realised this precinct is seriously fenced, including the installation of electric fencing, and there is no exit except through the main fortified entrance gates.  In the photo below you can see three layers of fencing, with barbed wire strung up at the top of the closer two fence lines- and the Bowen Bridge across the Derwent River in the distance.

20170125_084025.jpg

I walked to corners and along the fence lines without finding a gap, a gate or any chance of passing through.  I could see the Derwent River and the Bowen Bridge with Mt Direction overlooking both – but I could not reach them from the Technopark site.

20170125_084247.jpg

20170125_084753.jpg

20170125_085012.jpg

20170125_085019.jpg

So I had no choice except to leave the Technopark and try other options to reach the River.  The day displayed a stunning blue sky overhead and a moderate breeze which rattled the long grasses.  Mount Wellington was ever present as I walked away from the river.

20170125_085256.jpg

Before long I passed through the gates and headed away from Technopark with the aim to walk to the Bowen Bridge.

20170125_085847.jpg

 

Goodwood. Not sure about the ‘good’.

After walking across Goodwood Road (on Stage 10 of my walk along the Derwent River) which extends from the Bowen Bridge at one end to Glenorchy suburbs at the other, I was puzzled by a sign on one corner indicating behind it was a Model Park.  There were no trees. What sort of park was this? It seems this is a place for big boys to play with their model cars etc.  Special tracks were clustered in different parts of the ‘park’.

20150109_093005

Not much further along the road to the left (Innovation Drive –someone gave this name a lot of thought and presumably smirked in satisfaction) was signed as the entry to Tasmania’s hopes for technological innovation, Tasmanian Technopark.

20150109_093306

The Technopark was the brainchild of a government minister and his public service department around 2000. A small amount of information can be read at http://www.stategrowth.tas.gov.au/home/about_us/tasmanian_technopark. A federal government website has a whisper of additional information at http://www.australiangovernmentgrants.org/TASMANIAN-TECHNOPARK.php. I am surprised that there is no easily googled publicity about the achievements of this program. Can Tasmania ever equal the cut and thrust of innovation coming out of other small or remote places like Singapore, Finland, Iceland, etc?  What are we doing right and what could be done better to achieve successes?  Who knows? I couldn’t find any such information on the internet.

In the absence of any clear way to walk around the Derwent River edge of Dowsing Point, on which the Technopark is located, I thought it best to leave that exploration for another day and to continue along Howard Road.

Goodwood, in my experience, turned out to be the dog poo suburb of the Greater Hobart Area.  Excrement was everywhere in perfect form or squashed on the pavements, or the various colours dotted grassy verges.  I didn’t waste time on photography for which I am sure you are thankful – the choices were too great!

Firstly I turned left into Negara Crescent which was a street combining mean, low level, paint-flaking, unmown lawns, weed infested residential properties (okay – well not all were, but many were) with light industry such as Linen Services Tasmania, boat works, Anchor Wet Suits, Towbar and Crash bar repairs, fishing supplies, and a large unnamed workshop building emitting unpleasant chemical smells. Those houses which had Derwent River frontage sometimes had escaped overgrown blackberry infestations blocking river access in their back yards. There wasn’t a sense of wanting to live caringly or beautifully here. Accessing the River is impossible without entering private land around this locality. The built-in nature of some parts can be seen on the sign for a block of land that has been sold.

20150109_094257

By 9.45am I was joining back onto Howard Road. I walked on past bus stop 34, and the nearby Take Away Food shop and reached the Giblin Reserve around 9.50am. Photos of the surrounds are as follows:

20150109_095701  20150109_095658  20150109_094705

I sat for a while in the Reserve, watching a man in his car eating his take away meal, and taking in the surroundings.  This was a part of Prince of Wales Bay.

20150109_094717  20150109_095819

In the distance I watched the steam/smoke pouring from the zinc works of Nystar, a large industry owning considerable property along the Derwent River a little south from where I sat for a while and soaked in the atmosphere.

20150109_094734

Once I continued walking southwards around the Bay, I passed a kid’s playground, BBQ area, public toilets and ducks quacking.  When stymied by lack of water access around 10.05am, I walked up onto Gepp Parade and walked past a tree laden with not yet ripe nectarines, and later a row of junky looking boathouses. I wondered who wouldn’t be interested in removing their half sunk boat.

20150109_101243

Eventually, through the bitumen path, weeds began to multiply then suddenly this ‘formal’ path stopped and an occasionally trodden pathway through the weeds was all I had to continue on.

20150109_101335

I couldn’t help thinking that wherever a local government area is almost at the end of one and near the start of another area, there is more rubbish not collected and the general appearance of places is rather shabby. This has been the case on earlier stages of my walk, and now as I was at the extremity of the City of Glenorchy and coming closer to the City of Hobart boundary, the amount of visible rubbish and untidiness was escalating.

However, looking out over the water of the Bay (and if I tried not to study the weedy edges with their coloured flotsam and jetsam) to Mt Direction on the other side of the Derwent River, presented me with an attractive view.

20150109_101749

When I could get back down onto a weedy area, I followed man-made tracks and continued almost to the Sewage Treatment Farm (which I could see had wired fencing into the water that barred my continuous shore access) then headed up through the trees and onto a disused railway line. I crossed this, climbed a weedy rise spattered with rubbish, clambered over a metal guard rail and stood on Derwent Park Road which is the main road to Nystar and other industry located by the River. It was 10.25am when I reached this point. I had been plodding along for almost three hours.
