I will not name which city I call home, but all I can tell you is that it is somewhere in northeastern Nebraska. The only concerning thing about the city in question is that it is set in the middle of a danger zone called Tornado Alley. (Heaven knows I've had more than enough dealings with the reaper's scythe.) In my constant changing of planet Earth for my worldbuilding project, my personal goal is to make sure that northeastern Nebraska can be set OUTSIDE Tornado Alley. Here is what I've got so far: The Rocky Mountains have been rearranged to the extent that they start in the Canadian city of Churchill, then to Regina, Saskatchewan, then to Rapid City, South Dakota, then to Colorado Springs, then to Carlsbad and then meandering parallel to the Rio Grande River. They have also become higher--the tallest above sea level is 20,310 feet. Only the Rockies stand firm--no Coast Range, no Cascades, no Alaska Range, no Sierra Nevada. Instead, we've got ourselves a plateau covering the following: Saskatchewan, Alberta, Northwest Territories, Nunavut, North Dakota, Montana, Idaho, Nevada, Arizona, New Mexico, Utah, Colorado, Wyoming, Sonora, Chihuahua, Coahulia, Nuevo Leon, Tamaulipas, Durango, Zacatecas and San Luis Potosi. This singular plateau varies in elevation above sea level from 3300 feet to 16,000 feet. The entire Great Lakes Basin has been flooded, turning five Great Lakes into one Great Megalake. http://www.miseagrant.umich.edu/files/2012/05/Great-Lakes-Basin-Map-800w.jpg The Appalachian Mountains are rearranged to the extent of connecting the following dots--Galveston, TX; Little Rock, AR; Lexington, KY; Woodstock, VA; Glenn Falls, NY; QuÃ©bec, Quebec. The width varies between 65 and 227.5 miles. The tallest peak in the Appalachians is now 14,505 feet above sea level. Are these listed changes ideal to drive Tornado Alley off northeastern Nebraska but still retain the Midwest's prairie fertility in the process?
