11: Disappearing ice, meltwater streams and lakes
The final bit of the jigsaw puzzle at Seaham that tells us that the ice is disappearing, are the yellow sands and gravels at the top of the cliff. As the ice melts, it produces melt water. This begins to form streams and rivers and those streams and rivers transport sorted sands and gravels in […]

08: Striated rock
Here is a great example of a glacial erratic. This is a clast that’s been eroded, transported and deposited by the ice within the glacial till here at Seaham. It has got some characteristics that tell us it has been transported subglacially, that is within the sediment beneath the ice. Firstly, this boulder is sub-rounded […]
