High Sierra Nature Hello again. I am glad to be back. This time of year I spend as much time as possible in the high country of the sierras. I love the wildflowers at those elevations. This picture was taken at approximately 7,000 ft. These plants have to be hardy to survive, as do the insects that pollinate them and keep them reproducing. It amazes me how they survive the harsh conditions at these elevations This is a Mountain Aster with a Checkerspot butterfly busily doing his job.
