Barracks and Trees One of my favorite night views of Fort Snelling’s so-called Upper Post, taken between snowstorms. Similar Images ...based on the tags: clouds, ice, long-exposures, snow, streets, trees... This ruin was once the Toltec Mine, a producing gold and silver claim that operated into the 1940s. Summertime is when Duluth goes to the lakeside to listen to music, visit traveling fairs, and talk to neighbors about the smell of the lake. As seen from the castle walls. A cottage for masons infected with TB to live together. While it looks like a sidewalk, this is the roof the infamous (thanks to Ghost Adventures) steam tunnel that connects the steam plant and demolished Hart House. The tailings boom is the first and last thing you see when approaching the mountaintop shipwreck. Those able to work would be compelled to help fix up the facility, grow, harvest, and prepare food for fellow ‘inmates’, or work on vocational skills. The mill was powered, in part, by water flowing through turbines under it. After the flow worked the industrial heart of the flour mill, it was exit to the Mississippi here. A 5-minute exposure of the tunnel and stars, and even some of Duluth’s city lights bouncing off the clouds. A single off-camera flash in the tunnel gives the effect of an oncoming train. Looking down the walkway that traces the bottom side of the ore dock.
