Narrative Continued from Gallery 4

One rather impressive structure we toured was the massive Power Plant with four impressive cable-stayed smokestacks.  These stacks served the four c. 1915 oil burner boilers, magnificent equipment.  Pumps were used to pressurize the oil for distribution to the burners.  There were also air compressors, conventional boilers, electric generators, DC/AC converters, pumps, and support equipment.  The interior contents of the Power House are as impressive as its exterior.  We have never seen anything quite like it that I can recall in any other mining districts.  They may have had such things at one time, but nothing extant I can remember.  The tour wound up near the beginning and we were free to continue walking around exploring on our own.

The Kennecott Power Plant (ca1925) with its four smokestacks is the most prominent building in the north end of the town.  The Machine Shop (ca1916) is at the lower left.  The Electrical Shop and a storage building are located across the street.  The Kennicott (left) and Root (right) Glaciers and their moraines can be seen behind the buildings.

North of the Power Plant are a number of cottages (ca1915-1916) built for mill town families.  Some of these are now private dwellings, having been purchased before the establishment of the park.



(Above)  The Power House appears to be amazingly well preserved, probably because of its more recent construction and somewhat sheltered location.

 

(Right)  Four oil-fired boilers are located inside the Power House.

Each boiler is topped with a rather ornate pressure gauge.

Oil pumps supplied pressurized fuel to the boilers from a large oil storage tank located outside the building.


A belt-driven air compressor is one of the many devices in the Power House.

This device is an AC - DC converter.
