Sloops Cove is a little bay on the west side of the river, two 

 miles above Old Fort Prince of Wales. It was so called from 

 having been the wintering harbor of the small sloops kept here 

 during the 18th century for the purpose of trading with the 

 Eskimo to the north. The cove is 100 paces long and 50 paces 

 wide, and on each side are smooth well-glaciated rocks of green 

 arkose, rising, at first steeply, and afterwards more gently, to 

 about 25 feet above high water mark. At the back is a grass- 

 covered bar of sand and gravel 8 feet high, between the two 

 rocky hills, and separating the cove from a wide flat still cov- 

 ered with water at high tide as it was in 1746. The bottom of 

 the cove, almost up to high tide level, is composed of a fine 

 soft silt brought in by the river. Across its mouth is a gravel 

 bar through which project two low bosses of rock. Between 

 these the water now drains out of the cove as the tide recedes, 

 leaving it dry at low tide, and not " full of water " as stated by 

 Dr. Bell. I^orth of these bosses is a larger gap which has 

 been blocked by a dam of pieces of timber and large masses of 

 rock, many of which have been blasted from some place in the 

 vicinity, perhaps from south of the knolls, where the gravel 

 bar has since been formed. Outside the mouth of the cove 

 Robson's map shows the low water mark a quarter of a mile 

 distant: When seen by the writer in 1894 the low water mark 

 did not seem to be so far out.
