The location is in Utah, within the Eocene Green River Formation east of the Tie Fork Rest Area between Price and Provo along Route 6. It's the fancy newish rest area that has a bunch of train displays.
The image below was taken along Route 6 facing north, with the west to the left and east to the right. You can get a pretty good view of it within Google Street View Here.
Taking a closer look at the western fault above.
And an even closer look with the fault highlighter. The beds show significant offset by matching up that double bed located just above the arrows in the image below.
Normal Fault, as illustrated in the image below. It results from extensional forces where each side of the fault are moving away from each other. A Reverse Fault would be where the two blocks are being pushed towards each other.
Looking at the eastern portion of the top image.
We can see there are two, nearly vertical, faults lying very close to each other.
Both of these faults are also Normal Faults because of the same extensional activity as to the west. This makes sense because if the fault to the west resulted from extensional activity, it would be highly likely the entire area, if not the region, had undergone extensional pressures. This means that these couple of faults here would probably not be the only normal faults in the area and there are more normal faults spread throughout the area and/or region.
This is what is known as a scientific hypothesis. We looked the available data on the region and came up with a testable hypothesis based on it.
