Updated with more detailed plant list
Yesterday it took us over three hours to do the .7 of mile Mary Bowerman Trail near the top of Mt. Diablo. It had many flowers in bloom and was most inviting for photography (except for the wind in sections). A friend had recently found three species of Calochortus and also Lewisia in bloom a few days earlier. We didn’t find the Lewisia and saw only two Calochortus species but had a good time all the same. Highlights were the Mt. Diablo Fairy Lantern, Mariposa Tulips, Common Broom-rape, Whispering Bells, Red Larkspur, Wind Poppy and Chinese Houses.
I was mainly focused on photographing and looking at the flowers but did see and hear a few birds. The best sighting was a Hermit Warbler, which I had also seen two days earlier with the birding class in Mitchell Canyon.

Sandy,
Great photos! To see the Lewisia you have to go up on the rocks (brown shale) just past where the trail makes a left turn near the big rock. Same general place where the onions were.
