We’re teaching our sons about geology.

We’re teaching them about sedimentary, igneous and metamorphic rocks, about plate tectonics, about continental drift. We’re teaching them about the history of the earth, and the fossil record, and deep time.

It’s making us feel old.

Our sons want to learn about volcanoes, so we book an out-of-season holiday to Iceland. We stand on the edge of the Holuhraun lava field, staring down into the recently re-awoken inferno. Swarms of separate eruptions throw magma across the blackened, stinking landscape. Dressed in their silver heatproof suits, our sons look like an army of miniature henchmen.

We tell our sons about Eyjafjallajökull and Mount St Helens, about Krakatoa and Pompeii. We tell them how the eruption of Mount Tambora in 1815 led to a year without summer around the globe. We tell them about the supervolcano under Yellowstone park that may one day wipe out half the continental United States.

The spectacularly beautiful Icelandic tour guides – who are called Hanna Gunnarsdóttir and Solveig Gudrunsdóttir and Sigrun Eiðsdóttir – explain to our sons about Iceland’s geothermal energy infrastructure, how a quarter of the country’s electricity is generated using heat that comes directly from the centre of the earth.

Our sons try to get each other to run towards the lava flows, to see how close they can come before they burst into flames.

We are gently admonished by the spectacularly beautiful Icelandic tour guides for the behaviour of our sons. We are all a little bit in love with the spectacularly beautiful Icelandic tour guides. The mothers of our sons, of course, instantly become best friends with them and invite them to have a drink with us in the thermal pools.

In the thermal pools we drink incredibly expensive beers and watch the snow fall on our sons’ shoulders, settle on their hair. Our sons shiver in the brittle air, splash and jump on each other. They remind us of Japanese snow monkeys.

Hanna Gunnarsdóttir and Solveig Gudrunsdóttir and Sigrun Eiðsdóttir explain to us about the geothermal systems that heat approximately eighty-five per cent of the country’s buildings. They remind us that, geologically, Iceland is a young country: like our sons it is still being formed, as the mid-Atlantic ridge that splits the island right down the middle slowly pushes the North American and Eurasian tectonic plates away from each other.

We tell Hanna Gunnarsdóttir and Solveig Gudrunsdóttir and Sigrun Eiðsdóttir that we know how it must feel to be the western half of the country, helplessly watching the east speed towards the horizon at a rate of three centimetres a year. If only our sons were drifting away from us that slowly, we joke.

But they’ve already stopped listening.
