Pahrump's Wheeler kilns: the quiet back-room of Old West smelting

Smelting metal ores calls for high temperature and a source of carbon. Traditional smelting drew its carbon supply from charcoal, which in turn came from burning widely available wood products. Per Atlas Obscura, this logic in the early mining era of the American West produced a wide network of local charcoal production sites.

With transport still primitive and scrubland and forest abundant, every mining cluster had a charcoal supply line near it. The Wheeler kilns are one of the examples of that line in the Pahrump area of Nevada.

The kilns were laid out in a beehive shape, built from local stone. The design was a standardised piece of charcoal-production equipment in the American West of the era. According to the process Atlas Obscura describes, raw wood was loaded into the kiln, and a slow burn ran for roughly a month. At the end of that cycle the kiln was allowed to cool and then carefully opened.

The charcoal that came out was loaded for delivery to nearby mines. The smelting operation worked as a continuous activity to the degree it could rely on charcoal. That dependence is what explains the siting of kilns like Wheeler near the wood sources.

The local stones used in the kiln walls are typical of the industrial construction economy of the era. With no railway line reaching the area, hauling building material from a distance was economically impossible.

This period in the history of charcoal production is a visible component of the combined mining-forest-charcoal economy that belonged to the late-19th- and early-20th-century American West. A range of comparable charcoal kiln sites stood in Colorado, Arizona and Nevada in the same period.

The present state of the Wheeler kilns should be read in the context that the great majority of structures from that period have long since deteriorated. Local conservation work has helped the kilns keep enough integrity in their core remains to remain legible.

The forests around the kilns were significantly thinned during the period when they served as the raw material for the production cycle. That fact forms a concrete picture of the link between Old West industrial mining and landscape change.

The Wheeler kilns went out of active use after the smelting technology shifted from charcoal to coke. Once smelting started using coke instead of charcoal, most local charcoal kilns lost their function.

Today the Wheeler charcoal kilns sit as a quiet historical scene in the Pahrump area of Nevada. For visitors to the region, the kilns are an isolated witness to the industrial inner workings of the Old West.
