Queen foraging on flowers of Psorathamnus (Dalea) schottii, Indigobush. yellow dorsum band on abdomen, and rufous tip to abdomen seem diagnostic. Only 1 seen on 5 hour hike among lots of indigobush, which was today's favorite honeybee flower.
Note: two other photos of same individual submitted, should be with this one but I entered them separately. the 3 photos collectively show the field marks mentioned above.

Very very large bumble bee, compared to other bumble bees I have met. Has a a yellow tip on their abdomen just hard to see in photos. But in my video you can see it, tried to screenshot frames that showed the yellow tip
