I’m now finding time to travel back and appreciate what I missed. I cannot believe I dove off of the cliff into the mine knowing nothing about what was waiting beneath 🙈 A post shared by Suz 💫 (@suz.bsat) on Nov 4, 2018 at 5:27pm PST\nThe crystal clear mine is an excellent place to visit during the summertime, but there’s plenty of scenic hiking paths and ATV trails to enjoy as well. Or simply sit above the fence and take in the stunning view of the water below. You can even bring your dog along for the adventure.\nThe mine has been out of operation since the late ’70s, but you can immerse yourself in its rich history with all the informative signs placed throughout the location.\nView this post on Instagram #discoveron A post shared by Peter Cleary (@pclea) on Oct 2, 2016 at 12:47pm PDT\nAt one point in time, this man-made lake was a fully functional iron-steel mine. Lovingly referred to by locals as the Mighty Marmora Mine, the vast attraction stretches over 75 acres, with water as deep as 550 ft.\nInitially, giant pumps were installed in the mine to keep water from accumulating but were eventually turned off. Over time, enough rainwater was collected to officially classify the abandoned pit as a lake.\nView this post on Instagram Marmora Mine 1981 . . . . . . . #marmoramines #marmoramine #industry #mining #ontario #archives #history #mines #film #kokak #north #abadoned #abadonedplaces #gone #evidence #quigg #ue #adventure #rip #marmora A post shared by Time Stands Still (@_evidence_) on Apr 7, 2019 at 8:32pm PDT\nThere have been some talks of building a hydro plant at the deserted mine, so make sure to take in the views while you still can.\nMighty Marmora Mine\nLocation: Marmora, Ontario\nPrice: Free\nWhy you need to go: Stunning turquoise water, hiking trails, and rich historical value make this the ultimate summer day trip.Get Directions\nDisclaimer: Swimming is no longer permitted in the mine.
