For anyone interested there is 'summat' going on at Summit Quarry. This work seems to have progressed from the RAD 2022 update.

The main slab area has been partially filled in and routes like Grave's End (E1 5b) are up to 2m shorter. The ground is now level soft earth, bring wellies. There are also some small areas of damage from the excavator. The wall with Slight Wall (HVS 5a) on the other hand is about 1.5m higher
I didn't go and look at the area where the pool used to be, but there seems to be ongoing work at that end too. It feels like the whole quarry might be being repurposed for something.
Pylon wall area is however unaffected, for now...
