Unfortunately hoodoos don't last very long. The same processes that create hoodoos are equally aggressive and intent on their destruction. The average rate of erosion is calculated at 2-4 feet (.6-1.3 m) every 100 years. So it is that Bryce Canyon, as we know it, will not always be here. As the canyon continues to erode to the west it will eventually capture (perhaps 3 million years from now) the watershed of the East Fork of the Sevier River. Once this river flows through the Bryce Amphitheater it will dominate the erosional pattern, replacing hoodoos with a "V" shaped canyon and steep cliff walls typical of the weathering and erosional patterns created by flowing water. Indeed a foreshadowing of this fate can be observed in Water Canyon while hiking the Mossy Cave Trail. For over 100 years a diversion canal has been taking a portion of the East Fork of the Sevier River through this section of the park and already it's easy to see the changes the flowing water has created.
