20 GEOLOGY OF MOOSE RIVER GOLD DLSTRICT — WOODMAN. 



thick and in many places less than a foot deep ; and outcrops 

 for several miles are no more abundant than within the limits 

 of the settlement itself. 



Extent and topography. — The main settlement extends 

 rather more than half a mile east and west, and a third of a 

 mile nortli and south (pi. 1, tig. a). One mile west a district 

 locally called " West Mine," (pi. 1, figs, a, b), has been opened 

 superficially for economic purposes; and here also it has been pos- 

 sible to do some detailed work, which has aided in interpreting 

 the structure of the main field. Little could be made of the 

 intimate .structure in either part of the district without the aid 

 of subsurface workings, which range from shallow trenches and 

 larger quarries to shafts three hundred feet deep. No really 

 deep sinking has ever been done here. 



The topography of the region is that of a plain with very 

 alight relief. The drainacje is weak, although low falls are 

 numerous. Lakes abound. The general direction of the main 

 streams is northwest to southeast. Moose river, from which the 

 settlement takes its name, runs roughly south from Caribou, sev^en 

 miles north-northeast of the Moose River mines, where it has 

 expanded into several lakes. Between the two localities it has 

 a wandering course, often broadening into linear lakes, and in 

 places almost lost in swamps. At the northwest corner of the 

 settlement the river has been dammed to supply one of the 

 crashers, and again at the north for a similar purpose. 



From the pond first mentioned, west for a mile or more the 

 surface is fairly even, rising to a height of twenty-five feet 

 above the river, but for the most part without distinct hills or 

 ridges. The disposition of the drift accounts for much of the 

 slight irregularity. East of the river the land rises twenty-five 

 feet in five hundred, then very gradually for a mile. The south 

 side of the district, however, was largely a swamp until 1898. 



Division into units of area. — Like most of the proclaimed 

 gold districts of the province. Moose River has been divided by 

 the Department of Works and Mines into blocks, composed of
