Geology Walk in Land of Oak & Iron

Join Geologist Karl Egeland-Eriksen on another of his fascinating walks learning about how the different types of rock and the valley gorge were formed and the relationship between the geology and the industrial history of the Land of Oak & Iron’’.

The story of the lower Derwent Valley began some 320 million years ago, when what is now Britain lay close to the Equator.  The rock through which the river flows began its life as sediments deposited in a vast river delta.  Within these strata we find sandstone, shale and coal with occasional bands of ironstone.  Much of the bedrock is obscured by vegetation but, along this walk, we will find examples of some of the rock types present.

The valley itself is much more recent.  The deep gorge has been incised by glacial meltwaters some 20 000 years ago. When the glaciers retreated they left a cover of boulder clay which forms the top of the valley sides.  This too can be seen in places along the valley.

During the walk the processes involved in forming the rocks and the action of the glaciers will be explained along with discussion of the relationship between the geology and the industrial history of the ‘Land of Oak and Iron’.

The walk will last approximately 2 hours and cover just over 2 miles. Walking will be on paths but will involve steps up and down and some uneven ground.

For the walk, you will need to dress appropriately for the weather and wear sturdy footing.

Booking essential.  Tickets £9.50 per person.

Meet in the Courtyard at the rear of the Heritage Centre.

We're expecting this walk to be really popular as his previous walk sold out quickly, so please book soon to avoid disappointment.
