Fall Colors Are Peaking Right Now
The annual change comes slower at lower elevations in southern Utah. Bryce Canyon is up high and so the surrounding area is ablaze with color right now. Zion Park is lower and so the colors are just getting started there - the peak for Zion is probably 3-4 weeks out.
Get out and enjoy. This page suggests several drives where colors are particularly beautiful.
Be mindful of the weather. We're expected to get a big storm tomorrow (9-30-09), with rain in the valleys and snow at higher elevations. But the weather should improve for the weekend.
