This is an active landslide area and is still being monitored by UGS.
You have parked your car at what is now the end of Springhill Drive. Springhill Drive is named for the numerous natural springs that are scattered about in this area.. Springhill Drive used to continue farther to the south aprox another 300 feet. Springhill Circle extended aprox another 150 feet to the east from the center of the now missing section of Springhill Drive. The area was filled with homes, but in the late 1990's the land began to slide and caused major damage in this area, ultimately destroying 18 homes.
There was a gravel quarry in this area. The gravel was excavated and used for construction purposes.
The Springhill landslide is about 720 feet long and about 290 feet wide where it is crossed by Springhill Drive. The change in elevation is about 150 feet with an average slope of 21 percent. The depth of the landslide varies along its length. Along the north edge of Springhill Circle, the landslide is about 48 feet deep and likely deeper than 70 feet beneath Springhill Drive.
The UGS began monitoring this landslide in 1998 and continues to do so. Because this is still an active landslide area, the homes were demolished and Springhill Geologic Park was created in 2012-2014. This will forever be an open-space park because of the hazard this ever moving slide poses to the surrounding community. The slide moves at a different rate each year, sometimes slower and sometimes faster. The slide moved an additional 21 inches from when the park was completed in 2014 to 2020 when it was last surveyed.
The UGS began to survey the slide again in the spring of 2023.

The landslide formed in an old gravel quarry where gravels from ancient Lake Bonneville were excavated for construction-use nearly down to a layer of highly weathered clay-rich volcanic ash, sand, and silt (tuffaceous rock). This weak, poorly drained layer of clay-rich tuffaceous rock at the base of the landslide (forming the slide plane) and ample groundwater likely account for the decades of recurrent creep along this gentle slope. In places the tuffaceous rock is also overlain by a unit of volcanic rock fragments. The Wasatch fault zone crosses the lowermost part of the slide and may have enhanced weathering and clay development by providing a prehistoric flowpath for rising deep, hot groundwater.

I would recomend the short walk from the parking area to visit Stage 1 and Stage 2 for more information about what has happened and is continuing to happen in this area.
Information from 
To log this earthcache, you should visit Stage 1 and Stage 2 for for additional information about the area, then message me the info below.
1- Include the GC code, and all the people you may be submitting answers for.
2- Not including the gravel of the walking trail, what do you think is under your feet as you visit Stage 1 and Stage 2?
3- The slide moves more some years than other years. What yearly event do you think affects the rate of movement?
4- Do you think that the Wasatch Fault Zone, running through the park, could affect the rate of movement?
5- Do you think that this area will ever become stable enough to stop sliding, and why do you think that?
6- Post a photo at the location of you and/or a personal item with the head of the slide area in the background. You have to actually visit this park. Not including a photo with your log or photoshopping something will get your log deleted.
Thank you for visiting this park. I hope you have had an informative visit.
