Short-Lived Lenticulars With Irridesence

We were at Santa Rita Abbey yesterday and I observed small, lenticular clouds forming and then dissipating, turbulently, in very rapid sequence. I had never seen anything like this and any insights much appreciated. First photo in sequence below was at 01:03 pm MST and last was at 01:19 pm (the complete sequence has about 20 photos in it). There were about 8 to 10 separate clouds involved in the sequence.
