Aoraki-spotting from Halswell


OK, you can’t quite see it from Halswell… depending how you define Halswell!  But if you walk or bike for a bit (or even drive, if you must) it isn’t too difficult.

The details were provided to me years ago at Castle Rock by the late Phil Stuart-Jones, who got pretty sophisticated with compass bearings and sightlines, but I will aim to convince you without any of that stuff.

Aoraki/Mt Cook is about 196 km from our house in Halswell, almost exactly due west.  He’s a big fella though, and should be easily visible with the naked eye.  The key to it is to find Mt Somers.  Mt Somers is indicated by the arrow in the photo below (taken from Cooper’s Knob, with Gibraltar Rock and Tai Tapu in the foreground).  It’s one of the most obvious foothills, an unequal triangle with an easy-angled side on the right.  That's Mt Hutt on the extreme right under the clouds.


Next let’s see Aoraki from close up without much in the way.

That's Aoraki on the left, Mt Tasman on the right, from Malte Brun Pass.  This is the eastern view of the mountain, which is what we are looking for.

Now let’s have a look at Aoraki (indicated by the arrow) from the top of Mt Somers.  I think you can see it's about the same shape.  Keep an eye on the ice cap on the right of the summit that is in the sun.
  

Since Mt Somers is pretty close to due west from Halswell also, the view of Aoraki that we see from Halswell should be pretty similar to the one from Mt Somers.

So now let’s zoom in a bit on the first image.  The arrow on the right points to Mt Somers, and the arrow on the left to Aoraki.  As you can see it looks much the same, although a bit more hidden by the intervening ridge.  The piece of ice cap on the right at the top looks identical.  Pretty good eh!


Aoraki can be easier to spot in summer, when the ranges in the foreground don’t have so much snow; then, it is the only white one (although viewing can be quite a lot hazier at that time of year).  Where it appears relative to Mt Somers depends on which part of the hills you are on.  If you head towards Gebbies Pass from the top of Kennedys Bush Track it will appear on the left of Mt Somers, as shown.  I suppose a pair of binoculars or a telescope would make it better, but they definitely aren't essential.

Happy spotting!
