The International Portland Cement Company began mining limestone in Lakeview. A little later the Spokane Lime Company began to mine the limestone in Bayview, and later the Spokane Lime Company took over the operation. The limestone deposits were found to be approximately 200 feet thick in the 1880s. Mining the limestone continued until both quarries closed in the 1930s due to deterioration of the lime in both Bayview and Lakeview and the raised Portland Cement standards. The railroad spur to Bayview was abandoned, and five lime kilns are still visible on the Bayview north shore today.
This article describes the formation of sandstone that was located near first the site for Fort Boise and later the site of Boise City and the sandstone quarried at Table Rock. The Boise sandstone was used in the construction of the first building in Boise, the quartermaster’s building in 1864, and as a building material for construction of buildings in Boise. The sandstone was also used for curbing and sidewalks and the jail. The author states that the “principal area in the Boise region was Table Rock...” The article also describes other areas where sandstone was located.
The article goes on to state that the exact location of the quarries are difficult to find today. Some of them were located in the foothills near Fort Boise, some which were worked by prisoners from the Old Penitentiary starting in the 1870s. The quarries became a part of the penitentiary. The penitentiary, walls, and other buildings were constructed with the Boise sandstone and can be seen still today. Photographs of the penitentiary quarry work and Table Rock quarries, which opened later than those at the penitentiary, are available at the Idaho State Historical Society.
It is noted that the Jellison Brothers quarried sandstone on Table Rock. Sandstone for the capitol building was to be taken from the Jellison Brothers’ quarry, so the Capitol Building Commission purchased the quarry and contracted with the Idaho Stone Company to cut the sandstone for the project. About 1911 the Boise Stone Company bought out the Idaho Stone Company. Prior to that the Boise Stone Company had offered to purchase the quarry, but the offer was declined.
Many of the buildings “throughout Idaho and the West” were built with Table Rock sandstone while the Boise Stone Company operated the quarry. The author states that since 1940 the Table Rock sandstone quarry has been idle.

L & W was one of ten companies honored as “outstanding businesses and contributors to their local economies.” Other companies honored in Lemhi and Custer counties were Three Rivers Stone Corporation and the OB Corporation.
According to the article, Three Rivers Stone Corporation was established in 1996 in northern California. The company operates quarries in Idaho, California, and Oklahoma. The Three Rivers Stone Quarry in Idaho produces quartz sandstone, and there is a plan for expansion of the quarries. The company also has a mining and distribution center in Custer County.
At the time of this article, which is not dated, L&W Stone Corporation was planning an expansion at its Three Rivers Stone Quarry near Clayton which would add 140 new jobs to the new processing plant and expanded mining operations in the future. At the time of the article, the company employed between 145 and 230 employees. A new stone processing plant would be built down the Salmon River from the quarry, and the plans were dependent upon court decision was to affect the starting date. The prior January L&W Stone Corporation was one of 10 eastern Idaho companies that was “named as outstanding business and contributors to their local economies....”
According to the article entitled, “No agreement reached in L&W Stone case,” by Todd Adams, in The Challis Messenger online edition, stated that the suit was originally filed on September 2, 2004 by Western Watersheds Project (WWP). In another article entitled, “Bill would allow L&W Stone to buy quarry,” by Todd Adams and published online in November, L&W Stone had won their latest lawsuit when their interim mining plan was approved. According to this latest article, under a House budget reconciliation bill, almost 520 acres, that includes L&W Stone Corporation’s Three Rivers Quarry, the federal government would sell the land to L&W Stone Corporation.
The article also states that all of the quartz sandstone taken from the Three Rivers Quarry is hauled to a processing plant in California. It is also noted that workers migrate from Mexico to the quarry to work there for the March to December season, although some of the workers live in Custer County, Idaho. You can follow this story on the online edition of The Challis Messenger.’

Idaho quartzite is used as a building stone in Idaho and as far as Canada and Europe. According to this article “Oakley stone” or “rocky mountain quartz” is the most well known of this type of stone and is mined in the City of Rocks area of idaho from a group of quarries “situated on the west flank of Middle Mountain.” The elevation of the quarries ranges from 6000 to 7500 feet, and the quarries are located about halfway up the west flank of Middle Mountain. This stone was well known throughout the United States by the middle 1950s, and is considered superior for its durability and color. The stone was successfully marketed in Canada and European markets by the early 1970s. “In Idaho, the quartzite veneer is commonly used to pave entryways, to cover fireplaces and to cover the exterior of homes.”
"L&W Stone's quarries produce 90,000 tons of natural stone every year, including our exclusive Three Rivers Stone®, the most unique flagstone quarried in the US. Three Rivers Stone® is a quartz sandstone which is sourced only from our private quarry in central Idaho. The quarry has been owned by L&W Stone Corporation since March of 1996 producing approximately 700 tons of Three Rivers Stone® each week.
"Three Rivers Stone® boasts very distinct colors including golden brown, light blue, plums and warm grays. This beautiful range of color is complimented by crystalline formations called dendrites-named for the Greek word meaning 'tree', which the formations resemble. The dendrites in Three Rivers Stone appear like fossilized leaves, but these delicate leaf patterns are actually the microscopic paths of water that has seeped into the stone and calcified. This beautiful stone is a very strong and tested building material, withstanding pressure up to 18,000 lbs. per sq. in. and able to endure extreme temperature variances."
According to this report, “L and W Stone expanded its Three Rivers stone quarry near Clayton....”

The stone taken from the quarry is described as “a unique purple to light gray/brown siltstone rock or flagstone, which is used as a building material for patios, walls, and other features.”
Three Rivers Stone Quarry is described as “the largest flagstone quarry in the United States....”
L & W Stone of Orland, California, which owns the Three Rivers Stone Quarry, wants to purchase federal land in central Idaho in order the triple the size of the quarry. The article describes the quarry as producing an arguilite stone in colors of “gold, tan, beige and purple hues.” Rep. Richard Pombo, Republican in California, is involved in this matter.

"I do not know if the quarry, per se, is accessible, nor do I know the exact location. A historical plaque in a rest area off US95 reads: 'At the top of this hill 3 to 5000 years ago, prehistoric men had a rock quarry where they made a variety of stone tools [from obsidian]. Projectiles, knifes, and scrappers were among the tools made by these early people who camped at the foot of the hill. These nomads hunted deer and other game, collected plant foods and fished in the river here. They had spears and spear-throwers for hunting and fishing, and mortars and pestles for grinding roots and berries. Archeologists have not yet determined when this industry shut down.'"
The company operates three quarries in northern Idaho, and they only use local granite. The following is quoted from their web site with permission: "Idaho Granite Works quarry is located in North Idaho thirty miles from the Canadian border. This is a family ran business, established in 1969. Their customers and friends receive the highest quality products and outstanding customer service.
