OK, so I'm puzzled why Public Works has no idea what caused this sinkhole. Public Works should review their files on the Bonanza Mine.
Legends, the bookstore, is right on that corner. Legends' expansive basement links up to the network of the Bonanza mine tunnels that immediately underlie Washington Street from the Red Church on the north to Dayo Espresso on the south. Side tunnels likely go off in all directions, and I've been told that many of the old businesses on Washington Street used to have basements that connected to the old mine workings beneath.

Columbia Mom knows her stuff, and is correct. I don't recommend just pouring concrete in the hole, because it might take a lot to fill in all the tunnels.

Angels Camp is the same way. Nothing but a huge honey comb of tunnels just waiting to sink and swallow the town whole.

It doesn't look deep enough to be mine related, but is deep enough for leaking water pipes...but God knows, we don't have any of that around here in our water system...

Many years ago, there was a sink hole in the street by my house. I live on an old mine site as well. In this case, however, the connection between the drain pipe running from my house and the drain pipe in the street broke. Because the break happened in the street, TUD was responsible for fixing it (thank goodness! I can only imagine how much that would have cost us if it were our responsibility). It was approximately 18 inches across and probably 18 inches deep.

there are a lot of old waterways from the old days. If they fill it in,,,not knowing what it is..it will back up when it rains and make the problem worse.
Columbia Mom is absolutely correct.
