Patch it

We discovered that the small gaps in the side wall of the cave were the result of a badly patched hole someone had used to put an electric socket into the cave area.

Rather than trying to patch it again, Brian decided it would be better to knock it out altogether, and do a better job.

By doing this simple fix the temperature last night in the cave dropped by just half a degree, to 7.5°c . Whilst outside it dropped to -3°c. The work isn’t finished yet, and the final aim is to get a near constant 10°c without any intervention.

Every little win brings him closer.
