There does not seem to be an absolute period for max blooming, but it seems to depend upon how early the heat sets in. My best guess is the first two weeks of March, al least that is when I plan to ride out. An additional item might be related to late spring snow storms on the Panamint Range. This will have an impact on the valley as the westerly winds whip down from the mountains.
Dress warm and go early. Rain is always possible. Enjoy and ride sage.
