It must have been an ominous moment. Preston Gladd was out hiking in Colorado when a strange noise stopped him in his tracks. Unsettling whining was coming from an old mine shaft, and Gladd wasn’t going to venture down to see what was causing it. One week later, though, he returned – and made a disturbing discovery.
Gladd comes from Park County, Colorado, and in the summer of 2017 he had spent much of his time exploring the Pike National Forest near Fairplay in his home state. The location was of particular interest to Gladd thanks to the old mines that it contains.
In years gone by, the land surrounding the forest had been mined for coal, gold and limestone. However, due to the decline of these industries, many mines now lie abandoned. And these proved irresistible for an adventurer such as Gladd.
