The crater from the 1 July 1916 Hawthorn Ridge mine was originally 40 feet deep and 300 feet wide. Today it forms a figure of eight shape as a result of the subsequent British mine explosion on 13 November 1916.
The two overlapping Hawthorn Ridge craters are overgrown with trees, bushes and undergrowth and cover a total area approximately 450 feet long by 300 feet wide.
