Here is some information from the Utah Geological Survey website:
Cascade Springs is a refreshing oasis of lush vegetation, inviting pools, and cascading waterfalls located within the Uintah National Forest in the Wasatch Range, east of American Fork Canyon and west of Wasatch Mountain State Park. Water from the springs flows over a series of travertine terraces and pools and eventually continues on its way to nearby Provo Deer Creek. A variety of mammals and birds make their way here, including otters, beavers, deer, moose, elk, wild turkeys, hawks, hummingbirds, and numerous songbirds.
A trail system of paved paths, raised boardwalks, and wooden bridges consists of three interconnecting loops, permitting visitors a choice of walking only a short distance or completing all three loops for a longer walk. Benches are provided along the walkways, allowing for rest and taking in the beauty of the surroundings. Interpretive signs present educational information about Cascade Springs’ geology, water cycle, wildlife, and plant life. The lower pools loop is the most popular section with its easily accessible pathways and soothingly cool woods. It is very relaxing to walk along the maze-like configuration of boardwalks raised over shallow, crystal clear pools and waterfalls, surrounded by a variety of trees and flowering plants.
These pools contain abundant brown trout (no fishing allowed) believed to have originally migrated from the Provo River. The middle cascade loop begins at a wooden bridge situated over a waterfall with trails continuing up the slope on either side of the cascading falls. The rushing streams along these trails feed the lower pools.

I have been to Cascade Springs many times over the years. It is always beautiful.
