dant fossils, from which Mr. Whiteaves decides its age to be that of the 

 "Galena limestones of the west, equivalent t^ the Utica shales."^ 



Lower Fort Garry. — About 5 miles southwest from these quanies, 

 similar limestone is exposed on the west bank of the Red River, at Lower 

 Fort Garry, commonly called the "Stone fort," and along a distance of a 

 half mile to the south. It rises 15 to 20 feet above the river, its top being 

 about 730 feet above the sea. This also contains many fossils, amono- 

 which are several species, according to Panton, that are not found at East 

 Selkirk, but occur at Stony Mountain. The same formation has another 

 low exposure on the Red River, about 4 miles farther south. From the 

 former of these outcrops, close to the fort, Owen collected fossils which he 

 pronounced identical with those of the Upper Magnesian or Galena lime- 

 stone of Wisconsin and lowa.^ 



Stony Mountain. — Twelve miles north-northwest of Winnipeg, and an 

 equal distance west of Lower Fort Garry, is the hill called Stony Moun- 

 tain, well described by Panton as "like an island of limestone raised above 

 the surface of the surrounding prairie some 60 feet. * * * It is several 

 miles in circumference and resembles in outline the shape of a horseshoe. 

 The west and north sides are quite steep, and along the escarpments the 

 exposed edges of the strata are easily observed, while the east gradually 

 slopes to the prairie level." The highest beds at the quari-ies on the west 

 side of Stony Mountain are hard, brownish-gray, dolomitic limestone, about 

 40 feet thick (from 825 to 785 feet, approximately, above the sea), showing 

 only few and obscure fossils, chiefly corals; next is a reddish-gray lime- 

 stone, with clayey partings, about 10 feet, very fossilifferous, containing 

 many brachiopod shells ; and beneath these beds a well at the penitentiary 

 penetrated 60 feet of partially cherty shales, varying in color from yellow 

 to red. 



Little Stonif Mountain. — Eight miles south of Stony ]\Iountain and 5 

 miles west-northwest of Winnipeg, an outcrop of limestone, known as 

 Little Stony Mountain, has been quarried for lime-burning. The surface 

 here rises 30 or 40 feet in a half mile, from east to west, to the limekiln and
