Protect the Hoodoos

Sequence showing erosion of iconic hoodoo known as the Sentinel
Between 1980 and today, the iconic hoodoo known as The Sentinel was slowly reshaped until it suddenly fell in 2016.

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.
While we can't stop this inevitable fate, humans can help to preserve the Park's existing hoodoos by keeping to the park trail system. Believe it or not, just walking up to the base of a hoodoo will shorten its life span as your tracks weaken the clay slopes that protect the hoodoo's foundations. Staying on established trails ensures that erosion will not prematurely destroy the hoodoos that millions of people come from all over the world to see.
