Force Crag mine took centre stage again
last week, firstly with a school visit and then a day working with my volunteer
team. The school group was from
Braithwaite School in the village situated at the foot of Coledale Valley.
There may have been mineral workings on
Force Crag since the 16th century but significant mining began in
the 1800s to extract lead and silver.
When the price of lead fell to uneconomic levels, attention turned to
extracting barytes. In the mine's final years
lead, barium and zinc ores were extracted.
Eventually a collapse in the mine led to its being closed in 1990 and it
was handed over to the National Trust.
The buildings and machinery remain the only complete examples of their
type in the Lake District and the mine is now a Scheduled Ancient Monument that
is situated in a Site of Special Scientific Interest (SSSI).
For this school visit, John Malley (the
Trust’s Water Adviser) joined us. He is
the Trust’s lead officer involved in the project to develop the best strategy
for dealing with the water collecting in the old mine workings. So the children were able to learn a lot of
science, especially chemistry, from him.
They also had the opportunity to go inside the building and see the
machinery that was used to crush the ores and to make ‘rubbings’ of machinery
labels etc. as part of a pictorial record of the site.
It was an excellent day with one of their
highlights being the wearing of hard hats to go behind locked doors where they
could see the workings and experience something that the miners experienced!
Later in the week, I returned to the site
with my volunteers to do some work diverting water around the scree slopes
above the mine. This is one of those
jobs where the best option is just to set to work with shovels and wheel-barrows
and some hard work hand-digging to channel the water away from the screes. This should stabilise the slope. My great volunteers were, as ever, undaunted.

Me and Roy went digging in the rain. It was horrible, horrible. Then we went back with the volunteers when it
wasn’t raining. That was quite good.
