Fred, sounds as if you have experience but are looking for 'SOS' images.
The reason you see mainly SoUtah work from the State is that so many look at David Muench and others and go out and photograph what they did. Few go further.
Take a look at some of the work done by John Telford of Great Salt Lake. Take a look at the work of Craig Law on some of the quiet areas of Utah.
Visit the Salt Lake Art Center and get some inspiration as they have a number of programs, photographers and instructors intimately familiar with many areas of Utah.
Go a couple hours South and photograph the moving rocks... no need to drive all the way to Death Valley for it.
Trace the route of Bear River. Go just over the border to Wyoming and hit Fossil Beds National Monument. How about City of Rocks just over the border in Idaho?
Get away from the 'in your face' postcard photos and the places where you fight for a spot to put a tripod. Get out a map of the Transcontinental Railroad route and follow it a bit and photograph. The Uintah mountains are nearby. The Wasatch Mountains (Wasatch is a Ute term meaning 'Frozen Penis') have excellent scenic areas from Mt. Timpanogos to the ski areas to points North. The Raft River mountains to the North along the Utah/Idaho border are seldom visited. The Devils Playground in that area is pretty good.
Great Salt Lake and points nearby have a lot of interesting locations if you will go out and look a bit and not rely on others telling you where to go.
I stand by what I posted. If you can't find excellent places to photograph you are not putting much effort into the process. Take some classes at the SL Art center and work on creativity.
