It performed a similar function to the U.S. Geologic Survey in terms of mapping. Lines were formed as signals were flashed with mirrors three times a day. While canyons such as Santaquin and Payson were used by local residents for camping, picnicking, fishing, and some water storage, much of the east side of Mt. Nebo remained wild until the 1930s, when the Civilian Conservation Corps established a primitive dirt road stretching from Payson Canyon to Salt Creek Canyon east of Nephi. Before, there was a rough two-track road. It took drivers three hours to drive from Nephi to Payson Lake.
Thousands enjoy fall and summer drives along the scenic mountain road.
On a fall day, when the top of Mt. Nebo is dusted with the season's first snowfall, many enjoy the contrast of blue sky, white snow on a treeless peak and the reds, yellows, and oranges of changing leaves lower in the canyon. The peak's steep slopes and rugged terrain leave it wild. And that keeps those who love the Wasatch happy. .
