They were busy, all right, but that level of activity is not all that exceptional. Note that none of the operations were particularly long lasting. Years ago, in Pima County, we had three rescues in one day, which was a bit tiring. From what I have heard, their activity level has only increased.
Multiple call out weekends with large populations are fairly common. They are not so common in more rural counties like Coconino.
