In the spring of 1913, the US Forest Service at Pike National Forest planted 700,000 two to four year-old trees to reforest the slopes of the Canon. The project was completed in only three months.

The progression continued in 1914 when the first stone bridge was constructed followed by several others the following year. And in 1917 automobiles were allowed into the park. Due to the gasoline shortages during the Second World War, automobiles were restricted to driving through the park in the evenings. Since the road was so narrow, there were strict guidelines on hours travelers could ascend and descend the single car width. In 1932 after a trolley system was abandoned, a bus system took its place.
