The uplands of Merseyside have had an important influence on Merseyside and Liverpool throughout the region’s history.
During the last glacial period, ice sheets drove in from the north west and moved south towards the midlands. As they did so, they created the Mersey channel, the Alt and Ditton Brook channels, and the Dee estuary, thus forming the very basis of the landscape humans would later settle.
Since that time, humans have made use of the landscape created by the ice, in particular the higher ground not scoured as deeply. The mound adjacent to the Pool was the natural location for the castle when it was built in the 13th Century. Everton Beacon was a stone, and later wooden, contruction used to guide sailors up the dangerous Mersey channel. Of course, it had to be on high ground, which was why it was situated on Everton Hill near the northern mouth of the estuary.
The north west of England, on the north banks of the Mersey, has always been a marshy area, which is often cited as the reason why the Romans generally left the area alone. It gave the area names such as Blackmoor Moss and The Waste, and many areas required draining before they could be built on. For this reason it was the higher ground which was first used by settlers, such as that to the west of West Derby, which is slightly off the Alt flood plain, and the hills of Everton, Kirkby and Childwall and Mossley Hill in south-east Liverpool.
