On Utah Highway 59 outside Hurricane heading towards Pipe Springs there is an unpaved road wihich takes off to the north over Gooseberry Mesa and heads toward Smithsonian Bute. The DeLorme map book for Utah calls this Big Plain Junction. The road is not normally so difficult that a passenger car can not travel it but a higher clearance vehicle would be better. Common sense should apply though. Do not attempt this road after a wet spell. The views from the mesa back toward Zion NP are very nice. The road itself is a great drive it winds up back on pavement at Rockville on Utah Highway 9. Some maps refer to this as wire mesa.
