The Voids Beneath

Standard Post with Picture.

In more or less every issue, there will be tales of such things as “a mysterious collapse in a garden behind a 19th-century house,” that turns out to be a shaft leading down into a forgotten sand mine, or of “abandoned chalk mine sites” heavily eroding in winter rain storms, “resulting in roof-falls.”

“As most chalk mines are at relatively shallow depth,” Subterraneareports, “these roof-falls migrate upwards to break [the] surface as ‘crown holes’ or craters, which in the said winter [of 2013/2014] have been appearing in lawns and driveways, and even under houses, newly built in chalk districts.” http://www.bldgblog.com/
