Geological change takes thousands, no millions of years –right. Well yes, but no, actually. Look what has happened over the last three months, the wettest quarter for a hundred years; and then, today, in early July, a month’s rainfall in a day and the evidence of change is apparent all around. This evening (6th July), after the deluge, I took a walk to Martley Rock—the lanes were streaming, the sound of running water everywhere, silt washing over the roads, gravels too. Martley Rock site as flooded as it has ever been; trench edges slumping; good quality topsoil washed into the drains. And that’s in a few hours in one day. Stunning what can take place in an hour or two, never mind a century or a million years–today’s local landslides, stream banks washed away and trees brought down become tomorrow’s canyons, deltas and lakes. Right there on the road, wash away was being sorted by size—first the pebbles and gravel, then the larger sand and so on right down to mud. All you need to turn these into the sorts of rocks we are familiar with is a load more on top, massive pressure and a million or more years. Our lifetimes are so very, very short in geological timescales, but even we can catch a glimpse of these processes in action at times like these.
