In today’s cheap and superficial hype – too often the triumph of style over substance –  many things are marketed as having various specified advantages “and so much more”.  Well, here is a photograph that really does have “so much more”.  It was taken from the eastern wall of the rift valley, near Kijabe in Kenya, looking down westwards towards the rift’s floor, sometime in the late 1970s.  The rift wall here is not a single escarpment, but a series of small escarpments that gradually descend to the rift’s floor like a flight of huge steps.

This photo was taken from the top of the escarpment, looking down upon the top of the first of these steps which, because it still has sufficient altitude to attract rain and mist, is green and fertile.  This green but restricted area of land is covered in a close patchwork of cultivated plots, and dwellings roofed with thatch or corrugated iron. Beyond this step, the floor of the rift can be seen, browner and drier, many hundreds of feet below. Rising from these pale, dry lowlands is the dark and jagged bulk of Mt Longonot, a dormant volcano which last erupted around 1860. In the far distance, behind Longonot, the abrupt line of hills is the rift valley’s western wall.

So far so good, but there really is so much more here, for the fact is that the eastern edge of the African continent has been breaking apart for a long time.  The island of Madagascar broke away from the rest of Africa many millions of years ago and, during this lengthy isolation from the mainland, many unique (i.e. endemic) forms of life have evolved there, e.g. the Lemurs.

But that is not all. The Eastern Rift Valley (the one in Kenya) and and the Western Rift constitute further incipient splits in the eastern side of the African continent and, as I took this picture, I was standing on the western edge of another part of the continent that may split away to become an island like Madagascar in (the millions of) years to come. 

The floor of the rift is new crust that has moved upwards from the Earth’s extremely hot interior to ‘seal up the cracks’ in the disintegrating continent.  And hence the reason for the many volcanoes (including Mt Longonot) in this area – these were formed where the molten rock (magma) moving up from the Earth’s interior burst out (erupted) onto the Earth’s surface, as lava.  There are also numerous natural steam vents on the rift valley floor – these are the result of rainwater and groundwater coming into contact with the extremely hot rocks present not far below the surface of the ground.

UPDATE: I became an enthusiastic collector of rocks, minerals and fossils from somewhere around the age of five and went on to become a professional geologist – lecturing and research.  I’m very grateful for that background because it has given me a very solid idea of who, where and what I am in what might be termed “The Grand Scheme Of Things”.  To put it another way, if I’ve reached the “grand old age of 65”, then the Earth’s lifespan of 4,500,000,000 years make my lifetime seem like less than the blink of an eyelid – which is exactly what it is.  A knowledge of geology  also makes for new insights into landscapes.



  1. A geologist! I often wish I had a better understanding of the rocks and foundations I stand on. It seems that around here the geology is very complex, and I think the only way I’d grasp it would be to take a few field trips with someone who could communicate the geological world to someone unfamiliar with the terms. Maybe one day that will happen, meanwhile, I look and I wonder….
    (Oh yes, we are small, though an inflated sense of self and stuff prevails!).


    • Maybe you’d benefit from an introductory geology or earth sciences course, something like the adult education courses we have here? I am of course biased(!) but I do recommend the subject, I’ve found that it gives me a very solid handle on things – and especially so with the vastnesses of geological time. And, although I know relatively little about it, along with geology I’d recommend getting to know more about the universe – absolutely fascinating, and ultimately real, stuff! A 🙂


    • Truer words have never been spoken – although the Earth itself will persist of course until the expansion of the ageing Sun swallows it up – but it does seem like the Life supported on/near the Earth’s surface is in for a hammering. A


    • Kari, thank you very much! Smiling to you too! Yes, style and substance – we live in an age governed by power and money – factors which actually have governed most other earlier ages too – but it has now been found that the value of something (= money, one way or the other) can be enhanced by hype. Which is fine, as long as whatever it is has true value or substance – but the problem comes of course when true value is not there, where the hype is just empty hot air.

      A sideline here is the devaluation of adjectives – massive and awesome are examples: once they applied to really extraordinary things, now they are commonly used for everyday things. The important thing is to be able to see through the hype and the bullshit, to be able to see it for what it is. Adrian 🙂


      • Adrian…yes, yes, I couldn´t agree more…and all this have consequences…I believe now it is a moment of truly decadence, like the fall of the Roman empire…and “Societies in decline have no use for visionaries.”(Anaïs Nin)…well…we just have to wait a bit more, I guess…
        (…nice “talking to you” Adrian…)

        • I think the fall of the Roman empire is very apt – for my country (UK) if not your’s. We have had a vast empire, been a real world power and been enormously wealthy: all of those things are gone, but I think there is a disinclination, particularly on the part of our politicians, to acknowledge this, to acknowledge that we are now just an ordinary little country that, on the world stage, has steadily decreasing influence, and which is steadily becoming less rich.
