I love that area too. I hope you enjoyed it and had a good time. The official name for your "Mount Ryan" is "Ryan Mountain" though :) Thanks for sharing. Cheers.
We were there one year, about ten years ago when there was a lot of water in Barker Dam. There were ducklings, little fuzzy yellow duckling!!
Two more weeks and I'll be in Joshua Tree! My friend, who lives in Yucca Valley, tells me this should be a real good year for flowers due to all the rain.
