I thought I was a little overexcited when Theresa spotted a Steers Head (dicentra uniflora) and then realized there were perhaps a hundred coming up through the rocky soil. But then I read the description in
Wildflowers of Yosemite, p. 129, where they say: "The joy of seeing your first Steers Head will never be forgotten, for it is truly a precious treasure to find." They go on to say that though not a rare flower, it blooms only briefly just after the snow melts, so you have to be in the right place at the right time.
Sadly, we came across these flowers in the fading light and without a tripod, so we had to make do with half-second exposures with the camera balanced on backpacks and camera bags, which explains the rather high noise level in the photos.
I've since seen them many times and will eventually add some better photos. If you want to see them, the key is to keep your eye open for the leaves so you can find them in their non-flowering state and then go back during the narrow window when they're in bloom. The first photo in the gallery shows the leaves pretty well.
