Neumann’s Flash was formed when a salt mine collapsed in 1873. The Northwich salt mines had expanded rapidly without due safeguards, so inadequate supports were left to hold up the ground overhead.
A chemical industry developed around the production of salt, so the enormous holes created by this collapse, and the even more dramatic collapse of the nearby Ashton’s Flash in 1880, were in the 1950s used to dump lime waste. After dumping ceased, nature gradually began to recover and since the 1970s the area has been gradually developed into a country park, now part of the Mersey Forest initiative. Yes nature will recover, if given half a chance. See the story here.
Today, this is a great area for walking and birding, joining up with the nearby Anderton and Marbury parks.
The picture shows Neumann’s Flash from one of its three hides, with a fair sprinkling of birds on the water, as the sun slowly sinks towards the horizon.
