(Corporation of the City of Winnipeg)
(Little Stony Mountain Quarry
Dolomite Quarries (2)
SW1/4 - 34

Little Stony Mountain is a low ridge running north-south. The city of
Winnipeg quarry is on the eastern side of the ridge, and Egan's quarry is a
short distance farther south. The city quarry was sunk through 0.3-2.5 m of
overburden, 1.5-5 m of finely crystalline dolomite of the Gunton Member and 1.2
m of yellow mottled argillaceous dolomite of the Penitentiary Member of the
Ordovician Stony Mountain Formation.
Chemical Properties: Ca C03:
49.09-55.87%, Mg C03: 45.06-40.24%. For chemical analyses see Goudge (1944) and
Uses: Crushed stone for street paving, curb stones, lime,

EXPLORATION AND DEVELOPMENT
Little Stony Mountain quarry is located in SW1/4 Sec. 34, tp. 11 r. 2E
within the perimeter highway surrounding Winnipeg. Egan's quarry is in the NW1/4
of sec. 26, across the road allowance to the south.
1850: Around 1850 burning
of lime was undertaken on a fairly large scale. A railway spur was connected
from Moore siding on the Canadian Pacific Railway (about 1.5 km to the
southwest) to the quarry site.
1855: Production of lime ceased about this
1896: The City of Winnipeg purchased 32 hectares of land from Lord
1898: Production of crushed stone for road building and of stone
curbing was begun. The curb stones were cut by hand in the quarry and, like the
crushed stone, were hauled to the loading site by horsedrawn wagons running on
narrow gauge track.
1900: Two quarries were in operation; the City quarry and
Egan's quarry (a short distance further south). The City quarry produced
dimension and foundation stone as well as crushed stone. It was 90 m long and 45
1904: This was the peak production year for the City quarry. It was
the last year of operation of Egan's quarry by the Little Stony Mountain Quarry
1905: The City quarry wa now 450 m square and the increased thickness of
the overburden as quarry size increased resulted in operations becoming
uneconomic. A quarry site was purchased at Stony Mountain. (See M.I. card 62I/3
DOL 1). The entire plant and most of the town was dismantled, transported to
Stony Mountain by horse and sleigh, and reassembled at Stony Mountain during the
1850 - from about 1850 to 1885 burning of lime was undertaken on a
fairly large scale.
1989 - Production of crushed stone for road building and
of curbstones was begun by the city.
1900 - This was the peak production year
for the City quarry. It was th elast year Little Stony Mountain Quarry Company
operated Egan's quarry.
1905 - Operations ceased and the plant was moved to
