LOWER ECHO CANYON
September 6, 2016, two males attempted to descend Middle Echo Canyon, but did not look at their route description until they descended into Lower Echo Canyon. They continued through the canyon, even though the features did not meet the route description. By the time they looked at their route description, they were already too committed to exit Lower Echo Canyon. Eventually, they emerged at the top of Weeping Rock, a drop more than 10 times higher than the largest rappel in Middle Echo (this rappel is not permitted).
Luckily, they were able to call down for help. These canyoneers spent the night at the top of Weeping Rock where they were rescued the next day, after being stranded for approximately 15 hours. Even heavily traveled canyons in the park are routes, not maintained trails. Do you have a map and a route description? Are you confident in your ability to use them? When you enter a canyon and pull your rope after your first rappel, you are committed. You must complete the canyon whether you intended to or not and regardless if you are prepared for the canyon you are descending.
Tom: Comments? and was this you???
