Contrary to popular belief, you are just as likely to get struck by a tornado on a mountain as you are in a trailer park.

Quoted by Wikipedia, as well as numerous meteorologists:

Myth: Twisters are attracted to mobile homes and/or trailer parks.

Trailer parks consist of low-cost mobile homes with less structural integrity than traditional houses. A weak storm that leaves little damage to well-built structures might devastate a trailer park. Mobile homes do not attract tornadoes; they are just more susceptible to damage from them.

Myth: Tornadoes cannot form near rivers or cross them.
Myth: Tornadoes cannot follow terrain into steep valleys.
Myth: Tornadoes cannot travel over steep hills or mountains.

During the Super Outbreak, a tornado formed near Sayler Park section of Cincinnati, Ohio (near the Ohio River). It was among the six F5s of the outbreak. The city of Cairo, Illinois, which lies at the confluence of the Ohio and Mississippi Rivers, was also hit by a tornado that day.

The Tri-state tornado of 1925 crossed the Mississippi and possibly several other small bodies of water.

The F5 tornado of May 3, 1999 crossed the Yukon River in Oklahoma before it hit Moore, Oklahoma.

The Windsor - Tecumseh, Ontario Tornado of 1946 crossed the Detroit River from River Rouge, Michigan into downtown Windsor, Ontario, where the river is roughly 3/4 of a mile wide. The F3 tornado that struck on July 2, 1997 also crossed the river into Windsor.

During the Super Outbreak, after destroying three schools, the Monticello tornado crossed over a 60-foot bluff and the Tippecanoe River and damaged several homes.

During the Super Outbreak, the Guin tornado crossed Monte Sano mountain (1,650 feet) and gained in intensity as it descended the mountain. An F4 tornado caused damage in Murphy, NC after crossing a 3,000-foot ridge, and F2 tornadoes were confirmed in Roanoke, VA and Great Smoky Mountains National Park, NC. Tornadoes formed elsewhere in West Virginia, western Virginia, southwestern North Carolina, and north Georgia - regions of four states that are in the ranges of the Appalachian mountains.

Also, it's not too high for a tornado. In Salt Lake City, Utah, a tornado formed and damaged a streak of the city near downtown. Salt Lake City is well above 4000 feet. However, it should be noted that it is a rare occurrence for tornadoes to form west of the Rocky Mountains.


Myth: You're safe from a tornado in a big city.

Closely related to the "terrain" story (See Salt Lake City tornado just above), it is commonly believed that a tornado will dissipate in an urban area because of the tall skyscrapers. The May 3, 1999 tornado outbreak which struck urban Oklahoma City, and the tornado that ripped through the heart of downtown Fort Worth, Texas in May of 2000 are just two of many examples that negate this belief. While urban areas seem to be less susceptible to tornado strikes than rural areas, it is simply a matter of percentage of land area covered by these types of regions. Urban areas take up a relatively tiny surface area compared with the sprawling suburbs and the thousands of rural communities. Downtown Dallas is no less likely to have a tornado cross through it than an empty field in southern Oklahoma. While it is true that the typical urban building is a much more rugged structure than many comparable rural structures, it is not to be assumed that there is an increased measure of safety.

Some research has indicated that tornadoes are less likely to *form* over urban areas, as the skyscrapers tend to dissipate the vortex before it can reach the ground; however, the effect of the buildings is not enough to disrupt a fully-formed tornado that enters the urban area from a more rural area.

I live in Fort Worth, TX and I personally watched that tornado rip through downtown. You are not safe from a tornado ANYWHERE... you may be a little safer by living in an area where tornados are rare, but you're never 100% safe from them.
