Although I live in Reno, Nevada now, I was born in Ogden, Utah.
Utah has quite possibly the most amazing rock formations in the country, maybe even in the top 5 places in the world.
Here is a link to some of the national parks:
http://www.areaparks.com/utah.htmlCheck out Bryce Canyon and the Arches in particular. Most of the rock formations were created by Lake Bonneville, which used to encompass most of the state of Utah 15,000 years or so ago. It later receded into what we now call The Great Salt lake.
Info on Lake Bonneville:
http://www.ugs.state.ut.us/online/PI-39/pi39pg01.htmThe Great Salt Lake, is just that. It's one of the largest lakes in the United States and has no outlets, which is why there is so much salt, it isn't carried away from the lake. Another thing left over from Lake Bonneville is the Bonneville salt flats, info here:

It's one of the very few places that a single religion has remained together in a comparatively small space. They have branched out worldwide of course through missionaries and the sort, but the majority are still living in Utah. Although the mormons have probably one of the worst reputations, coming from actual experience living there, they are the most friendly and generous people as a group I've ever met.
As for Nevada, I'll try and stick with the city or Reno as it's almost a completely different place than Las Vegas.
Nevada itself used to be part of the "Utah Territory", basically if you just erase the utah/nevada border, that's the utah territory. Most Nevada cities started off as trading posts for the mormon settlers. Reno became a mining town. Later, when the casinos started thriving, it became a tourist town. For a quick tour of Reno's history, click this:
http://www.nevadaweb.com/cnt/r-t/reno.htmlLas Vegas gets the contracts for the biggest and baddest attractions, so Reno has fallen short in tourism over the last few decades. The great thing about Reno is your relatively close to just about anything you'd want to see and do. We're within an hour of Hiking, snow skiing, water skiing at many lakes including the awesome Lake Tahoe, off roading, historical landmarks such as Virginia City(fairly well preserved town from the Old west shoot-em-up days), our state capital and of course gambling if you so choose.
Both states have roughly the same climate in the north, very cold in winter, fairly hot in summer. Utah gets more precipitation than Nevada though.
Oh, to you savannah'ns, I just watched the movie "The legend of Bagger Vance". Although I can't confirm that the movie was filmed in Savannah, it was depicted as Savannah, GA in the movie. If that's where it was filmed, that's a beautiful place.
