Producer
Pumice, a subsidiary of Builders Masonry Products, sold its Rock Hollow Mine
to Joe Smith of Boise. The pumice was shipped by rail to Meridian, where
it was crushed, screened, and sold for use as lightweight concrete aggregate.

 
 Sand and Gravel.—Construction.— Construction sand and
gravel
production is surveyed by the U.S. Bureau of Mines for even-numbered years
only; data for odd-numbered years are based on annual company estimates.
This chapter contains estimates for 1991 and actual data for 1990 and 1992.

 The 1992 output of construction sand and gravel in Idaho increased more
than 28 % in quantity and 30 % in value from that estimated in 1991 and nearly
twothirds in quantity and almost 60 % in value from production surveyed in
1990. The three major producing counties were Ada, Canyon, and Idaho, accounting
for almost 56 % of the State's total. Major 
uses included road base and cover, concrete aggregate, and asphaltic concrete.
The bulk of Idaho's construction sand and gravel was transported by truck;
much of the remainder was used on-site. 
 
 Industrial.—Industrial sand and gravel production more than doubled
in quantity and doubled in value from that of 1991. Output came from three
pits in three counties: FMC in Power County; Monsanto near Soda Springs,
Caribou County; and by Unimin Corp. at the top of Freeze Out Hill east of
Emmett, Gem County. Uses for the industrial sand and gravel included glass
containers, sandblasting sand, specialty sands, and nonmetallurgical flux
(slag) in electric furnaces at elemental phosphorous plants. 
 
 Stone.—Stone production is surveyed by the U.S. Bureau of Mines
for
oddnumbered years only; data for evennumbered years are based on annual company
estimates. This chapter contains 
actual data for 1991 and estimates for 1990 and 1992. 
 
Crushed.—The estimated quantity of 
~ crushed stone produced in 1992 increased 
~ by almost 24 % and value rose almost 
~ 28% from that reported in 1991. 
~ Historically, top producing counties have 
~ included Bannock, Benewah, Caribou, 
~ Idaho, and Nez Perce. The bulk of the 
~ crushed stone produced was limestone 
~ and traprock. The top uses for the 
~ product included bituminous aggregate, 
~ flux stone, graded roadbase, and unpaved road surface. 
 
 Dimension.--Idaho Travertine Corp. operated a stone-cutting plant at Idaho
Falls, Bonneville County, and a travertine quarry east of the city. The company
has two quarries, one at Fall Creek, Bonneville County, where large boulders
of travertine were quarried and then shipped to its Idaho Falls plant for
slabbing, and another mine on Medicine Lodge Creek, Clark County. Decorative
sandstone was quarried at the Table Rock property near Boise, Ada County,
by Table Rock Sandstone Inc. Production was shipped to Idaho Travertine's
plant for processing, then used in the construction of new buildings at a
local college and for repairing the Statehouse in Boise. 
 A number of companies marketed Oakley Stone from quarries south of Oakley,
Cassia County. They included Northern Stone Supply Co. , which operated the
Rocky Mountain Quartzite quarry and sold slab quartzite for paving and facing
applications; and Oakley Valley Stone Co. , which mined and sold quartzite
from the Valley View Mine. The Rocktile Co. of Boise bought slabbed, roughed
quartzite, cut the stone to tile, and sold most of it as a facing stone to
both domestic and Japanese markets. 
 
 Zeolites.—Teague Mineral Products Co. mined clinoptilolite from
the
Chrisman Hill pit, near the old townsite of Sheaville, on the Idaho-Oregon
border just north of U.S. Highway 95. The company trucked the Owyhee County
ore
