Hey #GeologyMastodon may I get an assist in identifying this rock?! I believe I have hit bedrock about 1 metre down in my #BackyardProject #PoolPond excavation.

@MatWright @martin_fff cool!
ya, I don't think it's coal mine. I've never heard of a mine on this side of town (there is a mine in the hill under Argyle, the hill to the south of us. We're also near the top of the hill. -

Have you hit a continuous layer of that rock? Or just chunks of it embedded in the clay?

@JorgeStolfi definitely seems like a layer. The hole is 2m wide and I hit it at the same level on both sides of the hole.

But is it just solid rock, or a bunch of separate pebbles?
Those samples you showed are smooth with rounded edges. They look like they have been tumbled for some time at the bottom of a river or on a beach.

@JorgeStolfi Seems like semi solid sedimentary rock. I can only get the excavator bucket teeth into it and scrape layers of it off.. Definitely not pebbles.It crumbles in kind of light grey rubble.

@chris @martin_fff it could still be slag used for foundations, levelling properties

@chris @martin_fff I've been trying get archive stuff from the Nanaimo museum and city hall, but it's been a slog - so, our property was one of the original farms, given to rail and mine managers, we still have 3 of the original fruit trees
and I do think there is a shaft, probably ventilation, to a mine at the back end of the garden
does VIU have a Nanaimo archive?

@MatWright I believe they do. You could likely call the Library and ask. (I wouldn't recommend doing that next week though... a little crazy the first week back!

@chris hah, no doubt - and will do - funny, I never thought them before as a resource, but of course they should

@MatWright @chris fyi Nanaimo has an ARCgis Web App https://geoportal.nanaimo.ca/portal/apps/webappviewer/

@MatWright for sure! And who knows what there might be around campus in various history, geology or geography offices! Professors are pack rats!

@martin_fff @chris Martin - do you need to create an account? no free access

@chris we are the only property (I think) within Nanaimo city limits with a working ground water well, use for watering the garden - and for telling bylaw to fuck off when they come around about restrictions

@MatWright lol. rebel!

@MatWright @chris Well, I see no layers option. I guess that's what they've done. My Local Muni ARCgis never asked for account details. Mineshafts should be somewhere on their ARCgis

No expertise to share but following curiously… what does it look like when it’s dry?

@DavidM_yeg it is grey (see next reply in thread, just putting it up now). Someone mentioned mudstone or siltstone and I think that makes sense.
