下港矿石码头

The 下港矿石码头 is one of hg6668皇冠登录’s most iconic landmarks. A stone's throw from downtown hg6668皇冠登录, this mammoth concrete & 钢结构 苏必利尔湖 represents the city’s maritime and mining past. 

Constructed in the late 19th century, the 下港矿石码头 was part of a network of docks that facilitated the transportation of iron ore from the mines of Michigan's Upper Peninsula to steel mills across the Great Lakes region. 在其鼎盛时期, hg6668皇冠登录 was one of the largest shipping ports for iron ore in the United States, and the ore dock played a crucial role in this trade. Today, it’s the perfect spot for a classic hg6668皇冠登录 photo-op.

上港矿石码头

If you’re looking for a unique pastime while in town, take a moment to watch a freighter loading iron ore pellets at hg6668皇冠登录’s 上港矿石码头. Built in 1912, the Presque Isle Dock, as it’s also referred to, is still in use today. Find arrival and departure information, current locations and other details of incoming ships on MarineTraffic.com to plan for your outing accordingly.

这个钢结构的码头是1,250英尺长,60英尺宽, with the top deck sitting 75 feet above the water level. 它有200个口袋, each of which has a capacity of 250 tons of ore, for a total storage capacity of 50,000吨. Supporting the dock is a foundation of 10,000 wooden piles enclosed by a 12-inch thick timber sheet plank wall filled with sand. 每年大约9.5 to 10 million tons of ore are shipped from this dock.

这个过程

塔脱石球团的制作

矿石被开采和粉碎. Iron is separated using chemicals or magnets. Iron is mixed with a binding agent (like fancy cornstarch) and rolled into small balls, 大约一英寸宽. The balls go through a super-hot kiln, over 2,000°F, and come out as Taconite Pellets. These pellets, which are mostly iron, get loaded onto ore boats. Most of them head to Algoma Steel in Sault Ste. Marie, Ontario, the biggest steel mill. There, they'll mix them with coke and limestone to make steel.

装货上船

Ore arrives at the dock by train and is dumped into steel "pockets" or bins below the tracks. A chute is lowered to the boat's cargo hatch, and a door at the bottom of the pocket opens, letting the pellets flow into the boat. Loading time varies, but is typically about four hours. The First Mate is in charge of loading. They need to do it right to avoid stressing the boat unevenly. Each chute, or drop of ore, is about 20 tons.

Orehenge 

一年两次, locals and visitors in hg6668皇冠登录 have the opportunity to witness a stunning natural spectacle—the sunrise aligning perfectly with the center of the historic 下港矿石码头. Affectionately dubbed "Orehenge" by locals, this event typically takes place around November 21st and January 20th. 然而, catching this phenomenon requires a stroke of luck, as it hinges on clear weather conditions.

Observers can expect the sun to rise from the left corner of the Ore Dock, passing through its center before reaching the top-right corner. The optimal viewing time is around 8:26 AM when the sun breaks the horizon and becomes centered within the Ore Dock. To fully appreciate the spectacle, it's advisable to arrive around 8:00 AM, as some of the most brilliant colors tend to appear before the sun emerges fully.
