In August 2010, a collapse occurred in a mine in Chile, trapping 33 miners about 700 m below ground. The miners were discovered 17 days later via a drilled borehole. The underground conditions were very harsh, with high temperatures (>34 °C) and high humidity (approximately 85%). Within 2 weeks, most miners were experiencing skin problems, mostly in their feet. An antifungal cream, clotrimazole, was delivered to the miners through the borehole, but their skin maladies did not improve.
