Utah, less popular areas

While in Utah this October, I spent more time exploring less popular area, areas outside National Parks and less traveled areas of Parks. I've mentioned Escalante/Grand Staircase National Monument as an area I want to explore more. Another area I stumbled upon was Cedar Breaks National Monument. Because of its elevation, (over 10,000 feet) there was snow when I was there and I didn't spent a lot of time at the monument but I would like to go back especially if it is warm at lower elevations. There were some trails I would have liked to take.

I found another area by accident, I left the Interstate at Parowan to go to Brian Head. I gave that up due to snow and steep road but turned off at a road to Yankee Meadows. On the was was a very attractive local park with beautiful views and some trails. One particularly beautiful formation is Vermilion Castle, shown below. Several trails led to closer views but I didn't take any this time since the day was late.
I didn't do any exploring in Glen Canyon but I did see trails and roads I would have liked to explore. Again, something for my next trip.
