Abandoned mining tunnel [2]

Abandoned silver mining tunnel in Colorado, USA, circa 1870s to early 1900s.  This tunnel was used more as an expressway for transporting ore via ore bins to large silver veins deep w/in the mountain.  Unfortunately this section here has collapsed leading to a complete cave-in.  An unstable area shows signs of square set stoping which had failed, leading to the collapse.  Trickling water indicates that there is certainly more passage ahead, well over 10+ miles in fact!  Such intricate tunnels have in fact led to some mountains within Colorado caving in on themselves w/ others at risk.  Looking behind, at least there's light at the end of the tunnel, though it was tempting to photoshop the light out to make this view eerier.  Even this far back there managed to be a few mushrooms growing out of the wood.

More About USA

The United States is one of the most diverse countries on earth, jam packed full of amazing sights from St. Patrick's cathedral in New York to Mount Hollywood California.The Northeast region is where it all started. Thirteen British colonies fought the American Revolution from here and won their independence in the first successful colonial rebellion in history. Take a look at these rolling hills carpeted with foliage along the Hudson river here, north of New York City.The American south is known for its polite people and slow pace of life. Probably they move slowly because it's so hot. Southerners tend not to trust people from "up north" because they talk too fast. Here's a cemetery in Georgia where you can find graves of soldiers from the Civil War.The West Coast is sort of like another country that exists to make the east coast jealous. California is full of nothing but grizzly old miners digging for gold, a few gangster rappers, and then actors. That is to say, the West Coast functions as the imagination of the US, like a weird little brother who teases everybody then gets famous for making freaky art.The central part of the country is flat farmland all the way over to the Rocky Mountains. Up in the northwest corner you can find creative people in places like Portland and Seattle, along with awesome snowboarding and good beer. Text by Steve Smith.
