Burke Canyon

Gold was initially discovered in the early 1860s in the mountains to the north of the Snake River basin, which gave way to a large influx of prospectors.[3] Silver, copper, and other minerals were subsequently discovered. Idaho experienced boom after boom, and mining towns arose overnight, boomed, and then disappeared as the miners left for the latest rush. In 1884, miners discovered significant amounts of silver, zinc, and lead at the Tiger Mine in Burke Canyon. The Tiger Mine was sold to S.S. Glidden for $35,000.[4]

In 1887, Glidden began construction on a three-foot-wide railway to transport hardrock ore out of the Tiger Mine. Meanwhile, a buildup of 100,000 pounds (45,000 kg) of ore had accumulated from the various mines in the canyon, leading to the establishment of the Canyon Creek Railroad, which had its first shipment to Wallace on December 12, 1887.[4] The establishment of the railroad coincided with that of the town of Burke, from which the canyon takes its name. Burke was the largest mining community in the canyon, with a peak population of 1,400 in 1910.[lower-alpha 1] The community of Gem, just south of Burke, had been established in 1886. Both Gem and Burke attracted various miners as well as a large number of Swedish immigrants.[6]

By 1903, Burke Canyon was the most developed mining region in the Coeur d'Alene Mountains and was home to seven dividend-paying mines: the Gem of the Mountains, Frisco, Mammoth, Standard, Hecla, Tiger-Poorman and Hercules mines.[7]

On July 10, 1892, miners called a strike which developed into a shooting war between union miners and company guards. The first shots fired were exchanged at the Frisco mine in the early morning hours of July 11. The gunfire ignited a stock of dynamite in the Frisco Mill, causing the four-story mill to explode and kill six people.[lower-alpha 2][8] The violence soon spilled over into the community of Gem. From there, union miners who had successfully shut down both the Frisco and the Gem mines travelled west, to the Bunker Hill mining complex near Wardner, and closed down that facility as well. The Idaho National Guard and federal troops were dispatched to the area.[9][10] The incident marked the first violent confrontation between the workers of the mines and their owners.[8] Hostilities would erupt at the Bunker Hill facility once again in 1899.[11] In both disputes, issues included pay, hours of work, the right of miners to belong to the union, and the mine owners' use of informants and undercover agents.[8] Violence committed by union miners was answered with a brutal response in 1892 and in 1899.

Burke Canyon was the site of several natural disasters as well. Two major avalanches struck the canyon in the twentieth century: one on February 4, 1890, which killed three; and another in February 1910, which buried and killed twenty-five people.[12] In the days after the February 1910 avalanche, snow and rock continued to dislodge from the canyon walls, inflicting additional damage on the towns of Burke and Mace, and causing numerous deaths.[12] In August of that year, the Great Fire of 1910 would cause further damage to the communities in the canyon.[12] Three years later, in May 1913, the communities were stricken by heavy rains that resulted in significant floods.[13]

The Northern Pacific railroad considered discontinuing service through the canyon after the depot was damaged in a July 1923 fire.[4] The railroad also cited increased automobile traffic as a reason for discontinuing the line.[4] By 1939, the rail to Burke had been officially closed, and the tracks dismantled.[4]

By the late twentieth century, mining operations in Burke Canyon had slowed considerably. The Hecla Mine in Burke officially ceased operations on June 30, 1983, due to low metal prices.[4] The last mine in Burke officially closed in 1991, and the town and several of the surrounding communities became ghost towns.[12][14] Around 2010, the Hecla Mining Company has been exploring the potential of exploiting additional resource deposits in the Star mine. As of December 2012, Hecla invested $7 million in rehabilitation and exploration with published estimates suggesting the potential to recover in excess of 25 million ounces of silver from the site with significant zinc and lead deposits also present.[15]

Burke Canyon experiences a continental climate, marked by warm summers and cold, snowy winters.[17]

Decades' worth of mining activity resulted in various metals leaching into Canyon Creek, contaminating much of Burke Canyon. Leftover waste rock from mines leached cadmium, lead, arsenic, and zinc into the creekbed.[19] Ecologists found that long stretches of Canyon Creek were entirely uninhabited by fish due to the high levels of metal content in the water.[2] Canyon Creek is considered one of the Coeur d'Alene basin's Superfund sites.[19] The metals leached in Canyon Creek were partially responsible for the contamination of the Coeur d'Alene River, the most heavy-metal contaminated river in the world.[20] In 2010, the United States Environmental Protection Agency (EPA) moved forward with plans to dispose of leftover rock piles and contaminated soil in Burke Canyon.[19]

Various metals also impacted the local water supply of Burke Canyon: After the closure of the last mine in Burke in 1991, residents' water supplies continued to be sourced from pipes that extended into abandoned mine shafts. Consequently, the metal content of Burke's water supply was fifty times above that of federal water quality standards.[2]

In 2001, the EPA offered to buy out residents of Burke Canyon, citing water contamination in Canyon Creek, but residents refused.[2] The following year, the EPA ordered the town of Burke to comply with the Safe Drinking Water Act; however, given the small number of homes within the boundaries of the town, it would have cost each household an estimated $48,000 per year.[2]

For decades, raw sewage was emptied via pipelines directly into Canyon Creek from the residences in Burke Canyon.[21] By the turn of the twenty-first century, citizens of Burke had continued to dump up to 6,000 US gallons (23,000 l) of raw sewage into Canyon Creek per day.[2] In 2004, the Panhandle Health District (PHD) and Idaho Department of Environmental Equality (DEQ) tested homes in Burke to identify contaminations, finding a total of thirty occupied homes discharging untreated waste into the creek.[2] In 2007, the DEQ sequestered $220,000 in order to help residents install new septic systems to prevent further contamination.[2]

In 2016, the EPA announced its plan to construct a waste repository in lower Burke Canyon in order to alleviate waste accumulation in Wallace.[22][23] Some residents of the canyon objected to the repository, citing further pollution from diesel trucks used to transport waste in the canyon.[22]
