The photo's that Graham uploaded take me back..
I had a summer job with the old Arfon B. C. as a dustbin man and occasionally would go up with the lorry. Last time I went, I couldn't believe it was the same place.

I know what you mean. I remember going there with my dad to scrap a Renault 5, must have been around 1980 to 1982. We were told to drive down in to the quarry and leave it there. IIRC the place is pretty much full now.

my orders are to sit here and watch the world go by

Was having a potter round Dorothea and Cilgwyn yesterday. There's a large gated adit at the base of the large Cligwyn spoil tip. Anyone know anything about it. I wouldn't have expected a tunnel as the quarry is now full to the brim with rubish.

Also dotted about randomly some distance around the perimiter of the tip are several metal pipes embedded in concrete with locked lids. Boreholes or containers for some for of instrumentation?

I seem to recall considerable concern being expressed at the nature of the leachate that used to emanate from the "rubbish" dumping at Cilgwyn. This was in the days when there was little or no effective control on what was placed there.
This might explain the pipes.

Wasn't one of the lower pits that had rubbish dumped in it also a concern? It is one of two pits adjacent to the "road" approx. north east of Dorothea pit.

If the pipes are small diameter, and beyond the site boundary, it's more likely that they could be monitoring points for Landfill gas. They also could be monitoring points for groundwater. Leachate wells should be within the site perimeter. Waste Management Paper No 26 (HMSO) would give more detail for anyone interested.

Sounds something like that, although they must be 100' away in solid rock.

Cilgwyn tip is now full and Gwynedd's rubbish will be dumped elsewhere form the new year on!

There is a pit (cannot remember name) which, if you take the old Nantlle-Talysarn Road you soon pass after leaving Nantlle (after passing under the abutments of the Nantlle Tramway).

In the 1970s this was covered in rubbish. The rubbish formed a skin over the lake at the bottom. I remember seeing the biggest rats I have ever witnessed there.

It still looks a bit grotty, but nothing like it used to be. Still, I would not recommend a swim there.

Been injured while at work and are not to blame?

Get over it.
