Grand Canyonscope is a Donald Duck animated short released in 1954.^[1] It was Disney's second cartoon filmed in CinemaScope (following Toot, Whistle, Plunk and Boom), and was produced to accompany Disney's first CinemaScope film 20,000 Leagues Under the Sea. One joke has J. Audubon Woodlore breaking the fourth wall stating to the tourists in the CinemaScope version, "Uh, spread out, folks, this is CinemaScope" or in the non-CinemaScope version, "Uh, spread out, folks, this is a big canyon." Additionally, this short marked as the first Donald Duck cartoon to be distributed by Disney's own distribution company, Buena Vista Distribution, instead of RKO Radio Pictures.

Donald is taking a tour of the Grand Canyon. Although he just wants to enjoy the whole exhibition, this is made all but impossible by the constant admonishment from the rulebook-wielding tour guide: none other than Ranger J. Audubon Woodlore. Donald and Woodlore continue to irritate each other — Donald by innocently tripping over various regulations ("Don't drop rocks into the canyon; Don't bother the native Americans; Don't yell at Echo Cliff"; You can't be on the tour without a burro to ride"; et al.), and Woodlore by chastising him for it — until Woodlore himself disturbs Louie the Mountain Lion, the last lion seen in these parts since the Civil War.

To Woodlore's shock, Louie is, in fact, the same lion. He proceeds to don a Confederate soldier's hat and gives chase (after Woodlore's failure to gain his confidence by whistling the Confederate tune Dixie). Woodlore is caught in the middle as Louie chases Donald through the Canyon, which results in most of it being destroyed (notably, a number of natural rock formations are smashed).

With all the other tourists having fled, Woodlore sternly — and rather insultingly — demands that both Donald and the lion must restore Grand Canyon to its original state that they ruined; accordingly, he throws them two shovels and yells at them to start digging. Feeling extremely remorseful, Donald and Louie are actually crazy enough to go along with this; they mopingly begin the ponderous task of restoring the Grand Canyon to its former glory.
