DEPARTMENT OF LANDS AND FORESTS FOR 1935 53 



Appendix No. 19 



Extract from the Report and Field Notes of the survey of the base line, 

 District of Thunder Bay, west from Raynar Township, by Messrs. Phillips 

 & Benner, Ontario Land Surveyors, under instructions dated March 26th, 

 1934. 



Geology 



Between the point of commencement and the east boundary of the Nipigon 

 Forest Reserve, only a few outcroppings of rock were found in the entire length 

 of the line and these were granite. On the base line within the Nipigon Forest 

 Reserve, the Geology was reported upon by T. L. Gledhill for the Ontario 

 Department of Mines Report, Volume 34, part 6, 1925, and is shewn on the 

 map number 34-G. On this section of the line, there are quite numerous 

 outcroppings of rock and many claims had been staked along the line. The 

 record of such prospectors posts as were found along or near the line will be 

 found on pages 49 to 51 of the Field Notes and this is the only area in which 

 claims appear to have been staked prior to the survey of the base line. 



The line of prospectors blazes was very close to our survey line, so that, 

 if claims are to be transferred from the Kowkash Mining Division to the Port 

 Arthur Mining Division, very little change would be made in the areas or 

 shapes of the claims. 



The country along the line within the Reserve appears to have been 

 well mapped and no minerals of any importance were found by our party. 

 The declination of the Magnetic Needle was in fairly uniform progression from 

 East to West with no very marked deviation, the largest being about 8°. 



Of the total length of the line of 4815 chains, rock was exposed only 450 

 chains. 



Topography 



On the Easterly 50 miles of the base line, the country is fairly level with 

 few hills ranging over fifty (50) feet in height. There are long stretches of 

 swamp areas and other areas of level land. Between MacDonald Lake and 

 Ledingham Lake, the line passes through a rough, rugged country, the hills 

 ranging up to 140 feet in height and with numerous rock exposures. West of 

 Ledingham is mostly level with a few outcroppings of rock in the 11th and 

 12th miles West of the East Boundary of the Reserve. The Lakes and Rivers 

 East of the Reserve line are mostly shallow and have muskeg bottoms. 



Onaman Lake is one of the main topographical features along the line, 

 but portions of this are also shallow. 



Canoe Routes 



There was considerable activity in the vicinity of the Onaman River as 

 the Tashota Gold Mines had commenced to transport in supplies and re-open 

 the mine. The main route which is used leaves the Canadian National Rail- 

 way at Paska and follows the route through Wilgar Lake, Gledhill Lake, 

 Oboshkegan Lake and Barnum Lake. From the last mentioned Lake, the 

 summer road is cut directly South to the mine. This road crosses the South
