Below are photos from last week’s hike on the Dixie Mine, Sonoran, Promenade, Western Loop trails. (We also hiked a short section of the Andrews-Kinsey trail.) Linda and I hiked a little over 10 miles. The others turned back while still on the Sonoran Trail, hiking around seven miles total.
Linda suggested several of these shots. We both thought that the colors of the spurge (reddish ground cover) and brittlebush were interesting. (Note to Linda: When doing color correction on these photos, checking the values in Lab color space,I found that brittlebush leaves have a < 0 (green) and b > 0 (yellow) where b is roughly –a. This is why brittlebush looks “bluer” than a lot of other desert foliage, most of which have a b that’s significantly greater than that recommended for healthy foliage elsewhere. Note to others: Linda listened politely and patiently while I explained Lab color space.)
I think this is desert misletoe. Both Linda and I thought it was an unusual color, but it could be stressed either due to cold or perhaps death of the host plant.
