Ditch Creek, 1830 to 1994

Figure 1 1830
A stream (a) flows across a strike-slip fault.
Figure 2 1857
An earthquake with movement along the fault in 1857 causes displacement of stream (a) as shown. The amount of
displacement probably represents the amount of offset the earthquake caused. As the years go by, soil and sand
may bury and cover up parts of the original stream course (b).
