Devils Slide (Morgan) located on the south side of I-84 in Weber Canyon was a small industrial community (a cement workers town) at the Devils Slide, from which it receives its name; an earlier name of Portland had been rejected. In the 1920s the town had 529 residents. By the 1940s the school closed and only a few families resided there. In the 1980s. Today gravel and rubble cover what has become a ghost town site.
Devils Slide is in the upper Weber Canyon between Morgan 9.7 miles (15,61 km) west and Henefer, 5 miles (8,05 km) east-southeast.
The slide is a geologic limestone formation consisting of two vertical, parallel reefs 20' (15,24m) to 50' (15,24m) apart. The feature rises approximately forty feet (12,19m) above the canyon slope to form an enormous chute that rises 50' (15,24m) to 200' (60,96m) up the mountainside.
Millions of years ago a shallow sea covered this area leaving behind deep layers of limestone and sandstone known as the Twin Creek Formation. Folding and faulting tilted the layers and finally erosion exposed the two parallel walls we see today.
