At this elevation (about 9300 feet) at this time of year there are still a lot of widflowers. We saw these on a hike along Rock Creek on our recent trip to the Eastern Sierras. The smaller purple flowers are fire weed.
Other pictures that I've taken over the years in the Eastern Sierras can be seen here. www.flickr.com/photos/9422878@N08/sets/72157606897213537/
