Twentieth century fire patterns were analyzed for two large, disparate wilderness areas in the Rocky Mountains. Spatial and temporal patterns of fires were represented as GIS-based digital fire atlases compiled from archival Forest Service data. We find that spatial and temporal fire patterns are related to landscape features and changes in land use. The rate and extent of burning are interpret...
This paper descrihes the development and application of a computer-based simulation model of recreational use in the John Muir Wilderness Area in the Sierra Nevada Mountains of California, USA. The results of the study demonstrate, conceptually, how sitnulation modelitig can be used as a tool for understanding existing visitor use patterns within the John Muir Wilderness Area, estimating the im...
This analysis breaks down the congestion levels experienced during specific parts of a wilderness canoe trip. By explicitly addressing the heterogeneity in preferences for congestion during a trip, we are able to determine the relative value canoeists place on solitude at different points of a trip. Our econometric model utilizes a random effects probit framework to efficiently estimate the wel...
Analysis of tissue sections from transurethrally resected bladder tumours using anti-CD3 antibody showed the presence of T lymphocytes in intra-epithelial layers in eight of 12 cases investigated. In a larger group of patients, Tumour Infiltrating Lymphocyte (TIL) growth was established from six of 19 cases using Interleukin-2 (IL-2) and conditioned medium (CM) and resulted in the expansion of ...
The Wilderness Medical Society convened an expert panel to develop a set of evidence-based guidelines for the prevention and treatment of frostbite. We present a review of pertinent pathophysiology. We then discuss primary and secondary prevention measures and therapeutic management. Recommendations are made regarding each treatment and its role in management. These recommendations are graded o...

The location choices made by visitors have important implications for wilderness management. The cumulative effect of visitors’ choices produces recreational use distributions, and many studies show that these are typically very uneven. A small proportion of access points accounts for most use, and use of trails or water routes is very uneven. Some campsites are heavily used while others are ra...
