Glowing Mining Hole Locations?

[samoht04]

On another topic Wildredchild mentioned one of these and said by the Graveyard gate and to the right, I have had one in the same place. So I was wondering, are they all in the same-ish places? Like Spawner's?

Are these the glowing holes that indicate you've stumbled across a tunnel network to explore? If so I guess it would make sense if they're in the same place. Which town was this in? Perhaps others can try this out.

Yeah the ones that act like the catacombs. My one mentioned above was in Sunset Valley.

I tried that graveyard site in SV and didn't come up with anything, except a bunch of holes I now have to fill in, lol.  I went into graveyard, fence, right.  Nothing.  I tried a few spots and finally gave up.  Will keep trying.

I have found several spots in different places and if you fill one up and 're-dig' it, it may not be glowing anymore. I think this is just plain luck to find while digging.

Some holes glow once, then never again. Others glow once and can be found glowing later.

Glowing holes?  Explain please.  Digging?  You can do this?  How?  I've really never seen anything glowing anywhere, unless I have the Collector finding thing on.

It is caused by the Miner from Ambitions (Inventing) when you dig a hole, then sometimes the hole glows yellow and you have the option to explore it, it is very similar to the mausoleum.

Ahh.  Thank you.  I don't have Ambitions yet so that's why I'm not seeing them.  Today just might be the day I get it though!

I think there must be a chance to get a glowing hole every time you dig.  I can't imagine there being specific spots where they can happen, that just seems like it would be too many variables to work well within normal game play.
