Are We There Yet?

The lead-in to the silly season begins here. We don't really do it in a huge way, but I do like the trimmings - the tree and the food. For some reason red and green seem festively-themed, so here is meal number one: roast beef with jalapeno dressing served with radish and edamame salad with horseradish sour cream.

Meal number two is also rocking the red and green theme.

On the morning of Him Outdoors' birthday, we went for a walk around a new-ish track, the Ian Loiterton Track. Named in honour of Ian Loiterton (surprise!), the walk features information boards which explain the history, flora and fauna, and geology of the land. Ian Loiterton majored in geology for his BSc degree at the Australian National University.


Another information board tells us that the first European settlement of Aranda Bushland was in the mid-nineteenth century, when Francis Mowatt was granted land here, in the distyrict known as Weetangera. There was never a homestead in this area, the nearest being at the foot of Mount Painter. Cattle and sheep were grazed, and several old fence posts are still visible on this walk, as well as two farm dams and a low stone wall, probably built to control erosion.

Finneran's Road divides the forested upper part of Aranda Bushland for the woodland and grassland below. It was one of the earliest roads in the district, servicing the farms along the Molongo river, including this area, later called Glenloch. From the 1960s, when the suburb of Aranda was established, the forested slopes behind the houses were progressively excised from Glenloch and added to Canberra Nature Park. Later still, part of the lower grassland was excised to protect a patch of snow gums, rare survivors of the many that used to grow at this level in pre-European times.


"This walk is located on Ngunnawal Country, occupied by the Ngunnawal people for tens of thousands of years. We recognise the special relationship and connection that Ngunnawal people have with this Country. For time immemorial they have maintained a tangible and intangible cultural, social, environmental, spiritual, and economic connection to these lands and waters.

"Within this forested landscape evidence of Ngunnawal occupancy can be found. This evidence includes stone tools, scarred trees, and a nearby 'ring tree' signposting an ancient pathway. Our walk has been designed to avoid recorded Aboriginal Heritage sites, and any Aboriginal artifacts seen must be left undisturbed. 

"The area contains a major creek running south west from Black Mountain, edged on the east by a stee rocky ridge. The predominant underlying rock is the Pittman Formation-Acton Shale, which contains bands of chert, a hard rock used by the Ngunnawal for making cutting and scraping tools. There are also bands of quartz, which also were used for scrapers, though more difficult to shape into fine designs."

As we finished our walk, we were farewelled by this fellow.

Later in the day, we went on a tram-based pub crawl for birthday celebrations, taking in six drinking establishments, with several friends and fellow imbibers. I'll write a full post elsewhere, but here are the highlights.

We had planned a Christmas Eve event, but unfortunate events meant we had to cancel. We did have a couple of friends (Dr Kay and Patience Itself - oddly not pictured) drop by to share in the canapes and festive drinks we had prepared.

While we had friends here, we were able to share the birthday boy's cake, which is great, as we will be eating it for weeks!

Get your rocks on!

A beautiful afternoon calls for a run around the lake and so that's exactly what I did.

 
 
 
 
 

There is a place on the shore of Lake Burley Griffin that is reserved for a National Rock Garden. It purports that the purpose of this is to 'educate and inform present and future generations about Australia's rich geological heritage'. 

For now, there is a series of rocks with plaques affixed to them, naming their provenance and significance. They come from around Australia; from the inner depths and the outer coasts. Here they squat randomly on the ground as though they have been washed up, brought down or eroded through a series of natural disasters or geographical phenomena to this single spot. It's odd.

Close up the layers and patterns are remarkable and intriguing. Sections have been sliced away and polished, inviting touch. They are warm and beguiling under the sun, but will clearly be cold and impervious beneath the stars.
