Cartographic modeling of snow avalanche path location within Glacier National Park, Montana

Abstract:

Geographic information system (GIS) techniques were applied to the study of snow-avalanche path location within Glacier National Park, Montana. Lithologic, structural, hydrographic, topographic, and land-cover impacts on path location were analyzed. All path frequencies within variable classes were normalized by the area of class occurrence relative to the total area of the study area and were added to the morphometric information contained within INFO tables. The normalized values for each GIS coverage were used to cartographically model, by means of composite factor weightings, avalanche path locations. Buffers were constructed, weighted, and composited to related distances of paths to lithologic, structural, and hydrographic features. -from Authors
