<br />THE SLUMGULLION EARTHFLOW <br /> <br />INTRODUCTION <br /> <br />The year is approximately 1270 A.D. The place is a wind-swept mesa <br /> <br />on the western edge of Cannibal Plateau. SUddenly the water-saturated <br /> <br />clay and earth material give way and thousands of tons of earth begin to <br /> <br />move down the mountain and into the valley below. A few moments pass..... <br /> <br />............all is quiet once again. Several days pass and a lake forms <br /> <br /> <br />behind the natural dam of earthflow debris that has blocked the flow of the <br /> <br />river in the valley. <br /> <br />Today Lake San Cristobal stands as a dramatic witness of the past, <br /> <br />a sentinel of the Slumgullion earthflow. <br /> <br />Ori~in 2! ~ ~ Sl~ullion <br /> <br />In 1874, F. M. Endlich, a geologist employed by.the Hayden Survey, <br /> <br />noted the earthflow at the northern end of Lake San Cristobal and referred <br /> <br />to it as the Slumgullion mudflow, The term slu~ullion probably was derived <br /> <br />1 <br /> <br />~ <br />~ <br />~ <br />~ <br />U) <br />~ <br />
