Here we’ll explore the lumps of glacial till that have fallen off the cliffs. Discover the characteristics of the first till, containing local Permian Magnesian bedrock.

The Composition of Glacial Till: As we examine the glacial till, we can see a mixture of silt, clay and sand. However, what stands out is the abundance of local Permian limestone, giving the till its distinctive yellowish-buff colour.

Evidence of Glacial Action: If you take a closer look, you might be lucky enough to spot some striated clasts within the till. These striations are scratch marks left by the movement of the ice as it transported and deposited these materials.

The presence of striated clasts within the glacial till is classic evidence that this deposit was left behind by a glacier.

The lower at Seaham  till represents the first ice movement from the north-west to the south-east..
