The Utah Geological Survey has released a new geologic map of the Kane 30x60 quad, covering 1,900 square miles of parts of Kane and Washington counties in Utah and Coconino and Mohave counties in Arizona.
The map includes Zion and Bryce Canyon national parks and about one-third of Grand Staircase-Escalante National Monument. It represents the most recent compilation of the geology for this area and uses new mapping in many places.
It is available for $24.95 at the Natural Resources Map and Bookstore at 1594 W. North Temple, Salt Lake City, or from geostore@utah.gov. The online version is 38 Mb, so it takes a while to download.
