little cottonwood & joe’s valley will both be frigid in late Feb, little cottonwood could have as much as 50” of snow near the prime bouldering area. both have great ice if you’re into that. only bouldering/rock to be found that time of the year would be in the far southwest corner of the state in st george or in the virgin river gorge (technically AZ) and if your going that far south you might as well head to red rocks for more options.
