We love getting questions about mining, minerals and geology! We were asked about sinkholes and whether they are a risk when walking in the woods.

The short answer is yes, sinkholes are real but no, they are not a major risk and should not prevent you from enjoying outdoor activities.
Most natural sinkholes are caused by groundwater naturally eroding rocks like gypsum, salt and limestone which are water-soluble.

The water erodes the rock, leaving an underground cavern. Eventually, the weight of the rock and earth above the cavern causes the sinkhole to form. Sinkholes can form either gradually (i.e. a small depression appears and perhaps grows larger over time) or by sudden collapse.
The Point Aconi coal mine, before and after!
A surface mine operated at #PointAconi, #CapeBreton, from 2006-2013 and today the site is greenspace with ponds and ocean views.

It’s a great example of reclamation mining – cleaning up historical mines by completing extraction and returning them to nature or preparing them for other uses.

The mine was on the site of the old Prince Mine, which opened in 1975 and closed in 2001. It produced about 1 million tons of coal per year and sold it to #NovaScotia Power to generate electricity at the #PointAconi power plant, immediately next to the mine.

Misconceptions about modern #gold mining stem from historical mining practices that we agree were not good enough. No industry took proper care of the environment 100-150 years ago. However, historical sites like these have nothing to do with modern mining.

Modern mining is a sophisticated, science-based activity that takes proper care of the environment. Nova Scotia mines are stringently regulated by the provincial and federal governments.
