There isn't a specific mountain range in Utah that is solely created by earthquakes. While earthquakes play a role in shaping the landscape of Utah, the Wasatch Range, the prominent mountain range running through the state, is primarily formed by tectonic uplift, a slow and gradual process where the Earth's crust is pushed upwards due to the movement of tectonic plates.

Here's why:

* Tectonic Uplift: The Wasatch Range is part of the Basin and Range Province, a region characterized by alternating mountain ranges and valleys. This geological formation is caused by the stretching of the Earth's crust, which leads to uplift and subsidence.

* Faulting and Earthquakes: While earthquakes are frequent in the Wasatch Front, they are primarily the result of the fault lines that exist due to the tectonic uplift. These earthquakes contribute to the shaping and erosion of the mountain range, but they are not the primary force behind its formation.

* Erosion: The Wasatch Range is also shaped by erosion from wind, rain, and glaciers, which further sculpts the mountains over time.

So, while earthquakes contribute to the evolution of Utah's mountains, the primary driving force behind the Wasatch Range is tectonic uplift.
