SURFICIAL DEPOSITS IN THE LOUIS CREEK AND CHU CHUA CREEK AREA
Surficial geological mapping and drift exploration studies were undertaken in the summer of 1997 north of Kamloops in NTS map sheets 92Pil (Louis Creek) and 92P18 (Chu Chua Creek), as a continuation of the Eagle Bay Project initiated in the previous year (Bohrowsky et al., 1997; Dixon-Warren er al., 1997). The surticial component is pat of an integrated regional study centred on Devono-Mississippian rocks of the Eagle Bay Assemblage and Permian to Devonian rocks of the Fennell Formation. Massive sulphide deposits hosted in stratiform volcanogenic assemblages of the Fennell Formation at Chu Chua (MINFILE 092P 140) and syngenetic sedimentary rocks of the Eagle Bay Assemblage at Mount Armour (MINFILE 092P 051) suggest the region has considerable mineral potential. Polymetallic gold-bearing veins hosted in volcanic and volcanogenic rocks of the Fennel Formation at Windpass (MINFILE 092P 039) also suggest a high potential for gold in the area. Several placer occurrences of Au have also been recorded in the region.
Geological Survey of Canada's contributions to understanding the composition of glacial sediments
Drift compositional studies were initiated at the Geological Survey of Canada (GSC) in the mid-1960's in projects that drew heavily on the technology and approaches developed in Fennoscandia over the previous century. As this research progressed and expanded in the 1970's, its Fennoscandian character diminished and, like the geochemical exploration research program that it closely paralleled, drift prospecting began to acquire a distinctly Canadian character, imposed by the geographical and logistical constraints of climate and asymmetric population distribution. GSC research has increasingly focused on understanding and explaining the geochemical expression of the mineralogical composition of glacial sediments that are unaltered or only slightly altered by postdepositional weathering. Because glacial sediments are generated largely by crushing and abrasion, their various mineral and lithological components attain characteristic size modes based on physical properties such as cleavage and hardness.

Time and Heritage
As a historian studying what can be considered a form of intellectual history, I have slowly come to adopt Michel de Certeau’s observation made at the end of the 1980s that ‘objectifying the past, for the last three centuries, has undoubtedly left unconsidered time within a discipline that has continued to use it as a taxonomic instrument’. To a certain degree, time has become commonplace for the historian who has preserved or instrumentalized it. It is not considered because it is inconceivable, but because we do not think of it or, more simply, we do not think about it. As a historian attempting to pay attention to the time I’m living in, I have thus, like many others, noticed the swift development of the category of the present until it has become obvious that the present is omnipresent. This is what I refer to here as ‘presentism’.
