Your pictures labelled BLP 2651 and 2656 show the flowers of Parry Primrose or Primula parryi. Shaw's book Utah Wildflowers on page 152 has an example. The picture of the yellow daisy like flowers inpicture BLP2741a1 should be Helianthella uniflora or Little Sunflower. Each flower is on a single stalk. They come out after balsamroot and mules ears.
Your photos of Parry Primrose are truly lovely. It is difficult to get so many of these flowers together that are so pristine.
