Recession rate of Poudre Falls in Rocky Mountain Front Range, Colorado, USA

Description :
The recession rate of Poudre Falls in the Colorado Front Range is examined using an equation by Hayakawa and Matsukura (Eath Surf. Processes Landf., 28. 2003). In spite of stable tectonics and a cold semi-arid climate in the region, the estimated recession rate for 12 000 y. indicates rapid erosion of the waterfall. This indicates that the waterfall recession is a primary response of fluvial erosion after deglaciation, creating a narrow gorge below the waterfall. Further data collection will be necessary to assess the waterfall recession rates in such glaciated regions.
