This is truly fascinating. I'm wondering if anyone a the Historic Society knows more about "the one of 12 dams of the 2000 HP Hydro Electric Plant" are these dams still in operation?

Evidence of the dams still exist and most are still intact but no longer control water levels. These all occur around Slave Lake on the O'Donnell Road north of Northbrook however all the dams are now on private property. The main dam had a hole blown in it draining the main lake. This dam was maybe 20' high in some places. Several smaller dams run through the forest. The canal (penstock) can be seen from the road although you need to know where to look. Two photos exist below in the photostream. The most impressive is the penstock canal which routed the water from the dams to the turbines and powerhouse.

thanks! I'll have to take a drive this summer up to Harlowe on the Henderson Rd from Arden

O. B. Willmarth, President of Colorado Carnotite Company, a radium mining concern. He was in New York City in January 1914 on his way to Europe to meet with Marie Curie and argue for his right to continue exporting radium ore to Europe for processing: "All of us carnotite miners are at the mercy of the few radium factories in the world, and we depend upon the competition among them to get the value of our product. We work now under sufficient difficulty without being restricted to an insignificant American market." (16 January 1914, NY Times)

. Have a nice weekend

Awesome! Please check my photos here

I started a Wikipedia entry for him: en.wikipedia.org/wiki/O._Barlow_Willmarth
