Site locations and characteristics of miniature patterned ground, eastern Glacier National Park, Montana, U.S.A.

45--49

We examined a total of 68 sites with miniature polygonal patterned ground above treeline, along and east of the Continental Divide in Glacier National Park, Montana, USA. Patterned ground develops at three geographic site-types: convex uplands; concave mountain passes and cols; and valleyside slopes. Data were collected at each site to characterize the patterned ground morphometry. Morphometry was similar regardless of site-type, and occurrence was dependent on the presence of fine-grained material on older solifluction terraces or sorted nets.
