It seems that it was the wind from a storm, and possibly, in some cases, cattle. The hives are very light at this time of year and go down easily.
The pictures may not be representative, since I only showed the downed hives, and the same hives possibly more than once. By far, most hives in most yards were just fine, but there was a domino effect happening in several spots. After fixing up the worst yard, the rest of the day was mostly just driving in and out of yards, and I took fewer pictures.

Some of the hives were empty 'catch' hives waiting for swarms. Others were normal producing units. In the latter, at this time of year, bees are normally occupying only the second box. After five years of severe drought, the bees are not quite as good as we saw last time, but seem OK, especially considering we only examined the ones that were down and did not open the standing hives.
The rest of the boxes are empty at this time, but soon the flows will begin and the hives will expand and fill the rest of the hive. In the desert, wax moth is not a problem and no beetles are in the region AFAIK. Due toi the remoteness, access can be difficult, if the arroyos food and wash out, and, moreover, flows are unpredictable. Therefore, the best place to store the extra equipment is in the yards, on the hives.
We did not see any robbed out, even though the hives may have been down for a week, and some possibly longer. The ones that were down had patches of brood on several frames, and the brood, somewhat surprisingly, seemed OK despite having been horizontal and the boxes open to weather and other bees.
The boxes on the bottom are pollen traps, presently bypassed, but in place, ready for use.
