This talk weaves together two related datasets from east and west Cache Valley:

1. East Cache fault

1. Liquefaction that repeatedly deformed lacustrine sediment before and during high stand of Lake Bonneville 
2. Little deformation since then 

2. LIDAR confirms additional faults in West Cache Fault zone –

1. At least 18 km longer Dayton Oxford fault zone 
2. Hard linkages through the floor of Cache Valley 
3. An enormous fault scarp cuts right through Mendon, UT 
4. First documented Holocene ruptures along the D-O fault zone 
5. Several faults of WCFZ have both east and west strands 
6. Some strands span almost one km E to W.
