Rumors that a great arch in China could put southern Utah's natural wonders in the shade have fallen to a real-world truth: Utah rules!

Thanks to some dedicated scientists, modern technology and newly established measurement standards, Landscape Arch in Arches National Park has been declared 3 feet longer than Kolob Arch in Zion National Park.

At 290 feet and 287 feet long, respectively, the two redrock marvels head the Top 10 Arches of the World, a list that includes six Utah arches.
