Namib Desert’s northwest (#6 in series: Hoarusib in context, closer view)

 

 

Although the vantage point remains the same, this post’s images were shot with a telephoto lens; effectively, their view of the Hoarusib River is nearly seven times “closer” than that offered by the image in this series’ previous post.

At this point, the river and its surrounding landscape are quite unlike where the Hoarusib – rarely, and briefly – delivers a readily-visible flow of fresh water to the “Skeleton Coast” edge of the Atlantic Ocean.

Yet, where I stood – and the stretch of the Hoarusib visible in these photos – are only circa 30 minutes’ drive from the river’s oft-dryish mouth.

In a straight line, the ocean is almost certainly rather less than 20 kilometres distant.

Namib Desert’s northwest (#5 in series: Hoarusib River, in context)

 

 

I urge you to have a good look around: enlarge the featured image and zoom in on every element within a very complex landscape.

Finding the river is no great challenge.

However, you will need “eagle eyes” to be able to discern any evidence of the lightly-used access tracks on which “our” vehicles had travelled along some of the Hoarusib River’s lower reaches, and then up to the hilltop vantage point.

Within the photo’s field of view – which is similar to that of a naked-eyed human’s – those tracks are the only man-made feature.

No human lives here.

Not even a single signpost has been erected.

Namib Desert’s northwest (#4 in series: complex reality)

 

All of this post’s photos were taken from the bed of the Hoarusib River, less than 20 kilometres from where it (on occasion) meets the Atlantic Ocean.

Here, rainfall is a very rare event.

The featured image shows ducks flying along a river; most of the time, terrestrial animals can walk across the lower reaches of the Hoarusib without wetting their feet.

The ducks’ presence is much less “surprising” than most people imagine.

Namib Desert’s northwest (#2 in series: atop its edge “1”)

 

 

 

At 5. 26 pm on 14 November 2022 we stood on shifting sand, and in pleasantly cool air.

Below, in front of us, was the Atlantic Ocean, lapping Namibia’s “Skeleton Coast”.

We stood in a “sea” of sand – sand, only, it seemed.

However, the beach/coastal plain below us was clearly not devoid of vegetation.

Namib Desert’s northwest (#1 in series: Atlantic shore)

 

The world’s oldest desert gives its name to one of the world’s sunnier, hotter, dryer (and least-populated) nations.

Q: so why would a series that celebrates the northwestern portion of the Namib Desert begin with a photo taken on an Atlantic Ocean beach, as obviously-moist air swirled around me, on a cool early evening?

Aspects of Etna (#20, final episode: red rock stars)

 

When it is a very hot liquid, lava appears red.

As it cools, it becomes black/ish, and its flow slows.

As it cools more, it ceases to flow, is no longer lava, and has become rock – most commonly basalt, of a black/ish hue.

(“Punters” – yours truly included – often speak of “lava rock”. Geologists disdain that term. The geologists are right: “lava” is liquid, rock is solid. “Lava rock” is an oxymoron)

Basalt is the most common component of the earth’s crust.

However, not all volcanic rock is basalt, nor is black the colour of all relatively freshly-emitted basalt.

Also worth remembering: lava, steam, and hot gases are not volcanoes’ only “fresh fruits”.

Some volcanoes – and Etna is at times one of them – also “throw up” chunks of solid rock.

This post’s heroes may or may not be two such rocks.

Certainly, only their hue is currently “hot”.

On 30 September 2023 both were “cool”, temperature-wise.

Aspects of Etna (#17 in series: cloudless, suddenly, briefly)

 

The big volcano is very dynamic, always engaged in a closely monitored – but not entirely predictable – “dance” of destruction, construction, collapse, erosion and “quieter periods”.

The cloud-dance on Etna’s upper slopes is even more quickly-shifting – variously, arriving, departing, thinning, thickening, “setting in”, and “burning off”/“dissolving”.

Just a couple of minutes earlier – when I took the previous post’s photos – we were yet to enjoy more than fleeting glimpses of small parts of this post’s crater-scape.

Aspects of Etna (#16 in series: as the “cloud cap” begins to “burn off”)

 

This post’s photos were taken 15-20 minutes after the previous chapter’s.

We had walked up a little higher, staying on a marked path.

For several minutes, most of upper Etna had been invisible to us, but the clouds which had fully-enshrouded us were now fracturing, lifting, starting to “dissolve”.

At 11.40 am we were probably standing a whisker below 3000 metres above sea level; the pictured, freer-roaming folks were, variously, a little higher up or lower down.
