this report talks about approximately 9 p.m.on december 25, 1980, a intense rainstorn and the entremely wet antecedent conditions combined to trigger a landslide of approximately 5,000 yd3 at the head of polallie Creek Canyon on the northea..... plank of mount hood, oregon. the lands lide was transformed rappidly into a debris flow, which surged down the channel at iclocities of about 40-50 ft/s esowing and incorporating large volumes of channel fill and uprooted vegetation. When it readed the debris fan at the confluence with the East-fork Hood river, the debris flow de posited approximately 100,000 yd3 of satured, poorly sorted debris to a maximum thickness of 35 ft, forming a 750-ft-long temporavy dam accross the drannel... |
