Oddly, hardly anybody goes up the road toward the Kolob Reservoir. Everybody concentrates on Zion Canyon which is admittedly spectacular but often crowded with people. The Kolob is less spectacular but still beautiful, and much less populated.
At this time of year the weather can change overnight. Yesterday was warm and sunny, today started rainy and had been cold all day. At our home in Wyoming the conventional wisdom is that it can snow any day of the year. Okay, it is possible, but snow during July and August is doggone unlikely. A trace of snow during June and September is common, but won't stay around long. We have very long winters at 6300 ft. elevation, as you can well imagine.
