Imagine you had a Time Machine: where and when would you go to? Come with me back to Nowhere Wood, about 310 million years ago. That is long before humans, mammals or even dinosaurs existed, but frogs laid their eggs in pools, much as they do today.

 

Today it is hot, humid and very quiet: with no birdsong or animal noise, apart from the distant croaking of frogs.

We are in the northern foothills of an enormous mountain range, bigger than the Himalayas. It is unbearably hot and humid.  We are next to a river flowing from the Southern mountains, surrounded by thin horsetails that grow up to 10 metres tall. Tomorrow, there will be a raging tropical storm and the mountains will be pounded by its violence. The rain will flow in torrents in rivers towards us.

 

 

 

Nowhere Wood is located just below the equator, and we are looking up at the aftermath of a series of global catastrophes, which has taken hundreds of million years to happen. Two continents collided and sent shockwaves through the land, pushing upwards to form the mountains that we can see to the South of us. We are in a valley, downstream from the mountain peaks.

The mountain rock is soft and is easily weathered by the stormy wind and rain. Cascades of small, eroded particles surge down the mountain slopes, transported in the muddy river waters.

Mountains become tiny grains of sand settling at the bottom of the smaller rivers and streams running through and around Nowhere Wood. The streams are running from South to North, and criss-cross each other to form  a network of channels.

Layers upon layers of sediment are depositing in the streams, blocking the channels. Over time, the increasing weight of sand squeezes the water out. Minerals like feldspar and mica help to cement the grains together to form sandstone. These are the cliffs that we can see today at the far end of Nowhere Wood.

Pennant sandstone used to be  quarried to make roof tiles for the people of the town and local areas.

It is easy to think of living organisms having uncertain adventures through time and space. But the same is true of rocks, although on a much larger time scale.

1. Find out where the matter that makes up planet Earth originally came from.

2. Think about what has happened to the sandstone in Nowhere Wood since it was formed.
