Working with Lunan Bay Community Partnership, the Scottish Geology Trust as part of the Scottish Geology Festival will provide an opportunity to explore some of the local geoheritage. Join us between 11:00am – 4:00pm on the 26th September for this fantastic event!
Lunan Bay is well known for its miles of sand, but have you ever wondered what lies beneath? The river Lunan over millions of years has cut a path through the bedrock, forming a valley, and exiting into the sea at the centre of the bay. At either end of the beach are a mixture of sandstone conglomerate cliffs with intrusions of volcanic activity. To the north, dolomite limestone deposits led to the development of an 18th century lime industry and the Boddin Point lime kilns. The quarrying exposed jasper formations in the limestone, which now get washed down the coast to Lunan. We’ll discover an amazing variety of pebbles, find out where they come from and what they tell us about Scotland’s geology. We’ll also find out why the beach looks the way it does, and how it might change in the next few decades with climate change.
To the south at Auchmithie can be seen perfect examples of the sandstone conglomerate cliffs and eroded cobbles and pebbles on the beach, which are the same as those hidden beneath the sand at Lunan Bay.
The bed of the River Lunan exposes these stones and also at times the sea clears sand from other areas, to expose the underlying gravel banks.
For this event a display of the different types of pebbles that can be found will be exhibited along with additional information on the local geological context. There will be opportunities to speak to a Scottish Geology Trust volunteer about the formation and origin of these stones. The information display and activities will be on the beach by the river.
There are no local public toilet facilities. Access from the car park is by a ramp from the car park to the top of the sand dunes, then down an uneven path the beach, over a very soft sloping sand. The beach is firmer to walk on and the river a 600 metre walk to the south from the car park.
Children very welcome, but must be supervised by an adult at all times.
Stay safe: take care on the beach, watch your step and come prepared for the weather. Help prevent the spread of Covid-19. Follow Scottish Government advice and keep a safe distance from anyone who is not in your household.
This event is part of a series of Beach Pebble events around Scotland during the Scottish Geology Festival – find out more here.
