There are several national and state parks that were established as a result of tragic events. One example is the Johnstown Flood National Memorial in Pennsylvania, which was established to commemorate the victims of the 1889 Johnstown Flood, one of the deadliest floods in U.S. history. Another example is the Oklahoma City National Memorial and Museum, which honors the victims, survivors, and rescuers of the 1995 Oklahoma City bombing. The Manzanar National Historic Site in California, which preserves the site of the World War II internment camp where Japanese Americans were forcibly relocated, is another example of a park established to commemorate a tragic event.
