In a wet meadow. Bluer in life than in the photo.
Flower the size of a fingertip. Species best guess.
Hetch Hetchy section, somewhere along the trail between the dam and Beehive Meadow.
Half-awake at night near Beehive Meadow I could hear what sounded like a person walking slowly through the woods (why that didn't alarm and fully wake me up I have no idea). In the morning there were bear tracks on the soaking wet trail.
