Wittelbee Conservation Park August 29 - September 2nd 2018
  A couple of do nothing days in spasmodic showers and a cool wind.

In between showers, about 7 hours to replace broken speedo cable. The rear axle oil change (limited slip differential catching a bit at low speed full lock) was a couple of hours and had the desired effect.

  Friday (31st) we moved a couple of hundred km to Wittelbee Conservation Park, about 10km south of Ceduna.

The roads out of the park were a bit greasy, but solid.

  Intermittent showers and sunshine.
  Back to salt bush.
  We made a detour to Pildappa Rock.

The difference between granite and rhyolite is "not much".

The wonderful geological description on a sign at the base of the rock mentions the 5km of rock above the granite extrusion that was later eroded away.

That weight of rock explains to me the stress relief columnar faults in the Gawler Ranges.

  Similar to Wave Rock at Hyden (WA). But cheaper.

From one definition Granite is intrusive (doesn't reach the surface) while Rhyolite has similar chemistry but is extrusive (reaches the surface) so is more rapidly cooled.

I remain confused as the labels I have seen applied in some places seem inconsistent with the descriptions.

The erosion around the sides of this granite dome is apparently due to soil once resting against the edge changing the erosion. Nothing to do with wind as I imagined.

  One side is open to the weather. This side lichen covered.
  An uneventful drive to Wittelbee where it is also Spring.
  A small headland, and a collection of cormorants with a few gulls and turns.
  The granite next to the sea is obvious. I am standing on limestone.
  All around colour (even if it is white).
  (or green).
  The sun came out to play the next day. Warm until the wind arrived after lunch.
  Just a pleasant place to be.
  No luck with the fishing. Even with the support of an incoming tide.

Though the gulls that visited for short periods must have had some expectations.

  Crystal clear blue water. Only a couple of weeks since we were viewing the sea at the north of Australia.
  Another day, another sunset.On Sunday (2nd) evening we meet in Ceduna the rest of the party for a field trip into the Great Victoria Desert.

But first visit the cormorants (and others) at the headland.

  On the left is granite. On the right is limestone, on top of granite.

I tried digging, but couldn't find a single line where they are joined. Its probably relatively wide.

  Now that we know more about "karst formations" everything we see is "karst".
  Apart from the flowers that is.
  And the insects.
  And even the birds.
  A few clouds, a calm sea, another perfect day.
  Thevenard, just south of Ceduna, and really all part of the same town, is a port.


  An active port.

The north west corner of the Eyre Peninsula.

  Ceduna is on the main road.

A bit more manicured.
