Faults are fractures in the earth's crust which are caused by rock layers slipping and folding vertically. Fault lines occur along places which are easier to erode, such places include rivers, lakes, and along the bases of mountains. Fault lines can be distinguished from simple cracks by a break in the continuity of the rock strata.

The main fault of the Enderby area is one which begins in Sicamous and ends in Vernon. This fault slices through Mara Lake and continues, following the Shuswap River, until it reaches Enderby where it converts from following a watery path to following the base of the mountain until it reaches Vernon.

A smaller fault runs through Salmon Arm under Mount Ida and then runs nearly parallel to the Sicamous-Vernon fault. There are also several other small faults that run almost parallel to the main fault, one follows the basic path of Glenmary road and another runs through Mabel and Sugar Lakes.

There is evidence that many of these faults are older than the bedrock through which they run. In several places it seems as though the fault was formed and then the overlaying bedrock formed overtop the fault. This evidence shows in the fault that runs through Mount Ida. The fault is visible on one side of the mountain and reappears again on the other side.
