This was a wonderful short overnight hike near Colorado City/Hilldale in southern Utah, very close to the Arizona border. Map here
We hiked up the steep Water Canyon on good trail with good flowing water (as you might expect) before the trail zig-zagged upwards west of the canyon floor to 'top rock' - a small platform overlooking the canyons. From there we followed slick rock drainages holding good pothole water to the summit ridge of Canaan Mountain in a beautiful area called the White Domes.
We camped near here and the next day hiked west on an old stock trail with a mix of slickrock and deep sand amidst ponderosas with views north to Zion NP. On return to White Domes we followed the stock trail east to the head of Squirrel Canyon and back down to the trailhead. Squirrel also held good flowing water. Also see our hiking blog
