location of minidoka, amache, manzanar, tule lake , poston . rohwer, topar?

Answer 1

Minidoka is a town in south central Idaho. There's no town of Amache in the U.S., but there are an Amache Cemetery and a Camp Amache in Prowers County, southeast Colorado. Manzanar is a town in the Owens Valley of California, near Death Valley. Tule Lake is in northern California, just before the Oregon line. It's a lake, but there is a nearby town spelled Tulelake. Poston is a town in Arizona, near the Colorado River. Rohwer is in Arkansas, near the confluence of the Arkansas and Mississippi Rivers. There is no town in the U.S. named Topar. There is one in Kazakhstan. Could you have got the spelling wrong?

Did you know in advance that these were all places in the U.S.? Or that they were all towns? That kind of information can be very helpful. Sometimes the same name is used for towns in different countries.
