This picture was taken on my smart phone, and in a place off the interstate called "Red Rocks". A lot of places in the Red Rocks were mined back in the early 1900s, and these were likely used to get around during the mining. Not the only set of stairs, but more like the second set of stairs leading up. And up, and up.

Really pretty area, there are a couple other pictures I took, but I really like how the steps came out. They were fun to crawl on! Literally, crawl up 'cause they're so narrow.

Enjoy!
