Dike swarms and continental barcodes

It looks like a good number of the guesses for last week’s geopuzzlewere along the right sort of track. The most obvious topographic feature in the Google Earth image I posted is a patchwork of narrow linear ridges, which tend to either have an approximately northwest-southeast trend (I’ve highlighted some in red in the interpreted image below), or a northeast-southwest trend (yellow).

The Me Me Meme

Goodschist Chris tagged me for the latest silly meme:

  1. Take a picture of yourself right now.

  2. Don’t change your clothes, don’t fix your hair…just take a picture.

  3. Post that picture with NO editing.

  4. Post these instructions with your picture.

Yes it’s silly, and I actually have a serious allergy to cameras unless I’m behind them. I’m only succumbing because I’m tickled by the alliteration – or perhaps to prove that sometimes, I’m dressed in something other than field gear. Also, it gives me the chance to play with the otherwise entirely superfluous camera on my shiny new Mac.

As for the really fun bit, I call upon Laelaps Brian and Julia. Muhahaha.

How I got into blogging

Whilst I’m on the subject of anniversaries, I should note that I’ve just passed another milestone: last Monday marked the third anniversary of Highly Allochthonous. If you ignore the occasional hiatus, I’ve now been blogging for 10% of my life, which, when you think about it, is a tad scary. I’ve been in two minds about how to mark this marginally august occasion, but then I remembered that when I was sharing a few beers with my good friend GrrlScientist in London a few weeks ago, I’d promised her that I’d tell the story of how I got into this whole blogging malarky in the first place. It’s a somewhat rambling and convoluted tale, so if I end up boring you, just remember that it’s all her fault.

Geopuzzle #15

Since this whole geopuzzle malarky was kicked off by a mystery Google Earth image, here’s another one for you.

One (fairly) obvious feature of this image are the long linear features, which are almost certainly geological in origin. What could they be? animal, vegetable or mineral volcanic, structural or lithological?

Why geologists only get better with age

Last weekend, I turned 30. I suspect that this circumstance has more than a little to do with the strange mood that has both distracted my thoughts and stilled my keyboard in recent weeks; I usually tend towards the introspective around this time of year anyway, and I am as good as the next person at attaching unwarranted importance to arbitrary milestones. The fact that I’m reasonably satisfied with how my third decade on the planet went – even if, or perhaps because, it didn’t exactly go according to plan – and I have a number of good reasons to be optimistic about decade number 4, doesn’t seem to have prevented my contemplations from tending towards the morbid side of the spectrum, but such is the way of things with me. However, in my attempts to cheer myself up a bit, it has occurred to me that in many ways, age genuinely holds no fear for a geologist – and not just because by geological standards, even if I live past four score and ten I’m never going to be able to describe myself as ‘old’.
