Waterton Lakes National Park in Alberta and Glacier National Park in Montana lie along adjacent sections of the continental divide in the Rocky Mountains. In cirques or near divides there is evidence for two ages of glacial deposits. Younger deposits are generally well preserved, poorly vegetated, and bear no tephra and no or very small lichens. Older deposits are more poorly preserved, better vegetated, bear Rhizocarpon sp. lichens at least up to 92 mm in diameter, and bear tephra. The tephra often occurs in two different coloured horizons, but both are compositionally equivalent to Mazama tephra.The older advance has a minimum age of about 6800 14C years BP and a probable maximum age of about 12 000 14C years BP. It is correlated with the pre-Mazama Crowfoot Advance of the Canadian Rockies. Deposits of the younger advance are probably not too much older than mid-19th century, because some glaciers began retreating from the deposits about then. The younger advance is correlated to the Cavell Advance of the Canadian Rockies and the Gannett Peak Advance of the American Rockies.Both advances were minor. The older advance left moraines about 1.5 km or less beyond present glacier margins and depressed ELA's an average of 40 m below modern values.

Hedysarum (Hedysarum spp.) roots are a primary food of grizzly bears (Ursus arctos) in the Front Ranges of the Canadian Rocky Mountains. I studied the effects of recent forest fire on yellow hedysarum (H. sulphurescens) habitat by comparing root density, mass, fibre content, ease of digging, and use by grizzly bears in and adjacent to two prescribed burns that were conducted in Banff National Park, Alberta, in 1986 (Cascade Valley) and 1990 (Panther Valley). Digging was 12-14% easier in burned than in forested habitat. In the Cascade burn, yellow hedysarum roots were significantly more abundant and heavier than in the adjacent forest. This burn was intensively dug by grizzly bears between 1995 and 1997, but no diggings were found in the adjacent forest. In the Panther burn, no significant differences in root quality or mass were found. Bears dug few roots in the burn and did not dig in the adjacent forest. Their use of these two burns demonstrates prescribed fire's potential to create important yellow hedysarum digging habitat for grizzly bears in Banff National Park.

Abstract Dendroglaciological techniques are used to provide evidence of historical rock glacier activity at Hilda Creek rock glacier in the Canadian Rockies. The research focuses on the sedimentary apron of the outermost morainal deposit, where excavations in 1997 uncovered six buried tree boles that had been pushed over and entombed by distally spilled debris. Cross-sectional samples cross- dated with a local Engelmann spruce tree-ring chronology were shown to have been killed sometime after 1856. Based on the extent of the excavation, the data indicate that Hilda Creek rock glacier has continued to advance along the present ground surface at a rate exceeding 1 cm/year.

Direct evidence for an early Neoglacial advance in the Canadian Rocky Mountains is presented. Radiocarbon dates from buried peat and tree remains at Boundary Glacier suggest limiting dates for this advance of between 3800 and 4200 years BP. These data from Boundary Glacier are consistent with previously published dates for the onset of the Neoglacial and an early Neoglacial advance.

General. The life history of the lodgepole needle miner in Yosemite National Park, California, has been described (24). The Canadian outbreak was discovered in 1942 but intensive investigations were not commenced until 1948. Many differences have been noted between the Canadian and Californian life histories since the discovery of the outbreak.It is the purpose of this paper to bring together all information collected by the author and staff of the Laboratory of Forest Zoology at Calgary, Alberta, concerning the life history of the lodgepole needle miner in the Canadian Rocky mountains.
