Clan William: The Mines of Platteville and Eddie Lee Dalen

Early Lead Mines of NW Illinois/SW Wisconsin

Many of my ancestors relocated to Southwest Wisconsin from places like Ohio (both the Munsons and the Smiths, where their combined story started in Grant County). There were many opportunities in the Driftless Area that included all of Southwest Wisconsin. The Driftless Area was marked by the more rugged terrain than that of its neighboring plain states. This area was bypassed by the last continental glacier eons ago.

This terrain also made it prime for mining. The existence of valuable lead was discovered before the White Man settled the area. In the 1820s, mining began from Galena, Illinois north up the Galena River into Wisconsin. Thousands of Cornish miners flocked the area to work the mines, something they had generations of experience with in their native Cornwall, England. As time went on, many of those miners moved on to new mines in Michigan and elsewhere. I mention this because I have a bevy of Cornish immigrants on my mom's side.  

The peak of production in this area ran until the 1850s, but continued on for decades more on a smaller scale. Many of those in the area farmed and mined part time. 

Platteville, the later home of Charles Dennis Dalen and his wife Lucy Jane Munson (also a descendant of my previous story's Randil Munson - son of Calvin, who was big brother to my 4th GG Freeman Munson). 

Charles & Lucy's children were born in the township of Lima in Grant County, just a hop and skip from nearby Platteville. Charles was a farmer with five children: Francis, Arlington "Arlie," Charles Bird, Eddie Lee, and Frederick Louis. 

Platteville had so many mines operating over the course of time, that the town's design was affected. The streets had to be designed and built to avoid mine pits, so the town's roads are notoriously not-straight. And, unlike many mining towns, when mining died out, Platteville continued to thrive due to the establishment of The Academy (1839-1866), which evolved into the Normal School. The Mining and Trade School took the space in Rountree Hall when the Normal School moved to a new location and later became the Wisconsin Institute of Technology. Both became part of the UW-Plattesville campus in later years. Because of the deep ties to engineering, Platteville continued to thrive to today, bringing with it engineering companies who liked having engineering students so close at hand.

Platteville Miners

To return to our story, in 1905, the Trego-Anthony Mines were still operating. The Anthony was located at the east end of the Trego Mine (both located near today's Platteville Country Club). The Anthony mine was owned by one company, the Trego Mine was owned by HF Trego from 1901-1905. "It had a gravity mill and the concentrates were 25% Zinc and 25% Iron. There were many shafts and one adit to provide access to the mine; the main northeast Trego shaft is 90-feet deep; the main Anthony shaft is 75-feet deep."5

Young Eddie Lee Dalen, who most often went by "Lee," began working at the Trego Mine in Platteville in early 1905. He had the job of dumping the cart of mined ore. Somehow, he got caught up with a descending cart and was dragged down the shaft, falling onto a descending cage, being dramatically grabbed by the leg by his boss, and smashing himself onto some timbers. The early report expected him to survive, but his injuries were too great and he died on August 27, 1905. He was 22.
