Shoreline scarps look like faults with one exception, they follow contours. That is an important field camp lesson in the Great Basin. Faults have little inclination to follow elevation contours, whereas a lakeshore has little choice not to, so to speak. One interesting exception is when the two types of scarps are one in the same.

Trinity Canyon Fan near Oreanna, Nevada.

These kinds of areas provide a straightfoward perspective on how much alluvial fan activity has occurred since pluvial lake desiccation. Just look how that young fan overrides all of the recessional shorelines of Lake Lahontan. This is a hint toward a great study of Holocene sediment yield in the region that someone's student should work on.

The beautifully varnished fan remnant in the image below also shows an abrupt truncation along an elevation contour. Looks kinda like fault, except for its symmetry and the fact that depositional beach ridges and not erosional scarps are the lake level evidence.

Leach Canyon, Nevada

A stellar example of a wave-modified fault scarp is in the image below.

Here you can see a series of shoreline features as obvious concentric bands in the image. Note that the right (east) most linear feature is a fault. Note its weakly sinuous shape and that it departs slightly from the curvature of the adjacent beach ridge where cuts through a distinct fan surface. It then verges northward with the shoreline feature to become a prominent wave-modified scarp. There are many situations like this in Nevada where the fault and the pluvial scarp are composite features. This particular area has good contrast to show off the phenomenon.

Hmmm...yes...I can see that...maybe. I will go check for myself.
