The canyon is well known as the site of an unsuccessful 1974 attempt by Evel Knievel to jump across it in the Skycycle X-2 rocket.
 The dirt ramp built for that jump is still there and remains a tourist attraction (42°35'49.5"N 114°25'22.3"W).

On September 16, 2016, stuntman Eddie Braun successfully jumped the canyon using technology similar to that used by Evel Knievel 42 years previously.
