On my way to Capitol Reef from Great Basin, I took a couple detours to check out some local attractions.
I detoured through Parowan Gap to checkout some ancient petroglyphs made by the Fremont peoples and some fossilized dinosaur tracks. The petroglyphs are supposedly ~1000 years old, and the dinosaur tracks are slightly older. Definitely cool to see these up close - this is the sort of stuff I would expect to see in a Natural History museum!
I also stopped at Cove Fort, and old fort built by Mormon Pioneers. Its operated by the the Mormon Church now as a museum, which means that everyone was very friendly, the tour was free, and I left with a ton of Mormon paraphernalia.
