Regarding Historic Leyden Mine. By 1910 Leyden had 250 daytime employees and shifts both day and night. At 7:55pm the night of December 14, 1910, a fire smoldering in the veins broke into the motor room of Shaft #2. 25 miners 750 below the surface were in a fight for their lives. 10 men and 29 mules perished. The 11th man, Fred D. Newmeyer, died six years later as a result of his efforts to rescue the miners. Article written by Golden Historian Richard Gardner.
