View downward onto site with maximum observed lateral displacement along the Lavic Lake fault. Here a vehicle track and dry creek bed are laterally offset by approx. 370-480 centimeters. The orientation of fractures here is nearly North-South.

View right along the main rupture zone, and also visible is a subsidiary fracture from lower-right corner coalescing with the main break in the middle distance.

View downward onto vehicle tracks crossing the fault at a high angle. One can see 2.5 to 3.5 meeter right-lateral displacement of the tracks.
