Wish I'd Ignored my Geography Teacher


My last exam in Geography (a long long time ago) was the worst exam I ever did. My sole remaining memory of the course was learning why Heathrow Airport was located where it was over and over again. But if he'd taken me to places where Geography came more alive I'd probably have pursued it further. The desert South West is somewhere every budding Geographer/Geologist should be taken.

If you have difficulty believing there are huge forces involved, there's Waterpocket Fold, where the strata have been broken and forced above the surface. You can drive along it for miles, although the best views are from the air.



If you have difficulty believing water can erode the landscape dramatically over eons giving us the Grand Canyon. There are smaller versions such as this in Canyonlands National Park, where you can 'help' the process if you trip over the wrong rock.


The whiter rock on top is the hard stuff, and the red rock is is like a very soft sandstone. Note the columns on the left where the red rock is eroding underneath the white, eventually the whole thing completely collapses.


On the way it creates some wonderful shapes.

But as you wander about taking photos, you can't really tell what is underneath you. Every now and then you realise you've crossed a crack like this. Any stones you drop in just completely disappear. So does mean you're standing on one of those columns?
