Beautiful new signs at the MMHP trail head. Nicely done Rick Semo and Ivan Hellen
Standing in the Lorenson Baseball Field at the Miners Trailhead in 1900, this is the view you would have seen of the Aurora “A” Shaft.
You know you’re in mining country when you see a headframe, the entrance for miners to an underground mine and the exit for the ore.
