Description :
In July 1988, the Flatfish Range Fire burned over the type-Pinedale moraines at Fremont Lake, Wyoming, and caused extensive exfoliation of exposed boulder surfaces. Fire-induced exfoliation may account for differences in boulder size and abundance on Pinedale and Bull Lake moraines. Surface dating methods using varnish or cosmogenic nuclides may yield exposure ages that are too young if the consequences of ranges fires are not considered when sampling boulder surfaces that are within about 2 m above ground level.
