Nowlan was accompanied by the late George Dalziel on this trip, who apparently saw three deer on this occasion. The first published reference to deer is found in Rand (1944), who reported second-hand information from the following localities along the newly con- structed South Alaska Highway: Bucking Horse River, Steamboat Mountain, Summit Pass, Lower Liard Crossing, and Coal River. The latter two loca- tions were close to the Yukon border. Clarke (1946*) assumed that deer had crossed into the Yukon in these areas. Clarke (1946*) also reported deer within the Yukon from the Nisutlin River and the Teslin area. Youngman (1975) summarized anecdotal infor- mation about deer to the early 1970s and listed records from Ross River, Carmacks and the Takhini River west of Whitehorse. Discussion Mule Deer have colonized most suitable habitats in the southern Yukon, with the latitude of Dawson (64°) constituting the northern limit of their current distribu- tion (Figure 5). The notable exception is the record of a Mule Deer doe and her fawn along the Dempster Highway near Chapman Lake (64° 50'N, 138° 25"W) by M. Villeneuve in summer 1998. This is the northernmost record for this species. To the west, Mule Deer have crossed the border into Alaska, most likely following the valley of the Ladue River upstream toward Tok during the 1980s. It is assumed that they first entered the Yukon from the Liard River drainage of northern British Columbia in the late 1930s to early 1940s. White-tailed Deer were first observed in 1975 by W. Ward at Tagish Lake, only a few miles north of the British Columbia border. The northern-most sighting, made in 1998, comes from Moose Creek near Stewart Crossin
