Abandoned mining towns like Gilman, Colorado, heavily mined for silver, lead and zinc since the late 1800s, then ordered to vacate in 1984, due to toxic pollutants that contaminated the groundwater. To this day, Gilman remains unsafe and off limits to the public.
自 1800 年代後期以來,像科羅拉多州吉爾曼這樣的廢棄採礦城鎮就開始大量開採銀、鉛和鋅,然後在 1984 年因有毒污染物污染地下水而下令撤離。時至今日,吉爾曼仍然不安全,且不對公眾開放。
