yes, October is a great time of year for southern Utah......a buddy and I were backpacking several years ago on a remote southern Utah plateau in October and, at one point, I saw blue sky, white cotton-ball clouds, green evergreens, yellow cottonwoods, red Indian paintbrush, orange slickrock cliffs, and purple lupine (and a skanky brown cattle tank!) - all in one visual sweep......one of the great views I've experienced in one of the great regions of the world........
