This location is right next to the town of Ingersoll. It lies next to the main CN rail line. One of many limestone quarries in the area, this closest facility to Ingersoll is now abandoned, the adjacent pit is also abandoned and filling up with water and contaminants. View Ingersoll in Google Maps Satellite view and you will see a large body of water east of Ingersoll. This is the abandoned pit.
Although the facility itself is abandoned, it sits on active Carmeuse Lime property, and further down the tracks there are active facilities. This facility is still monitored.
The buildings are very large, and it was once easy to get inside. As of right now it is not clear if one can gain access. Various pieces of machinery remain inside the buildings and surrounding areas. This is a very large facility and some parts of it may not be entirely stable. One of the two main suspended conveyor structures between the two main buildings has caution tape strung across the path inside.
To get to this facility via 401: Exit at Plank Line/Harris St. interchange, Ingersoll. Follow Harris north into Ingersoll. Turn right at the Gas Station to remain on Harris. Harris turns into Pemberton at Charles. Follow Pemberton down the hill to second set of tracks. This is the CN line. Following it East will eventually lead you to quarry. It is visible from the rail crossing.
