If one was to try and identify a Mecca for off-roading enthusiasts, you could make a solid argument for Moab, in southeastern Utah. As you might imagine, Jeep helped make this a destination for all things four-wheel drive, in particular the Easter Safari Jeep and Red Rock 4-Wheelers. With 2016 marking 75 years since the first Jeep wearing seven-slotted grille left assembly lines, and America’s National Parks are also celebrating their centennial.

Such an anniversary is a once-in-a-lifetime event, and Jeep managed to talk the National Park Service into giving three of its Jeeps access to one of Moab’s most notorious, and closed-off, obstacles; the Lion’s Back. It’s closed off for liability reasons because it actually lies on private land, but Jeep worked with landowner Michael Badger to open the Lion one more time for this unique celebration.

A gathering of Jeep executives set out for the Lion’s Back, driving a 75th Anniversary Edition Grand Cherokee and two-door Wrangler up its 45-plus degree sandstone tail. The third member of the Jeep fleet was a limited edition Wrangler Red Rock. At the steering wheels were Jeep’s Tyler Ruby, Mark Allan, and Jim Repp, and as you can see in the video above, this is not a trek for the faint of heart.

This may very well be the last time anybody has access to the Lion’s Back, and while there are a great many off-road trails available to enthusiasts, it would be nice if it didn’t take the backing (and insurance) of a major corporation to be able to access these landmarks. On the other hand, we have to appreciate Jeep’s dedication to preserving and celebrating its own history in ways its fans will truly appreciate.
