fabulous work and reminds me to take my geology friends along with me on walks more - they tell me what the rocks are and how old etc. Fascinating.I especially like the tough little grass fighting its way to live on this difficult terrain.
Thanks, Rolina. Boy, that would be great to have a personal geologist to follow me around during my wanderings in the desert. A botanist would be great too - I wish I knew what kind of grass that was!
