Methane methinks!
Introduction
The photograph on this page of Methane methinks! by Anthony O'Neil as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

Lindow Moss generates subterranean emissions and there are ground level metal vents dotted about the area. I suspect this installation (unmarked) has some role in monitoring or measuring the gasses generated. Parts of the Moss are grassed-over refuse dumps which are even more likely to be sources of methane which, if uncontrolled, could lead to explosions.
