Who says the desert is empty? This one looks pretty full.
This is what happens to a barrell cactus when it looses it top bud--it splits in two and produces an attached twin
It has been extraordinarily dry in this part of Arizona, so I was really surprised to see this rock covered with green lichen.
Here is a closeup. Will have to try to find out the name of this lichen.
And this is a packrat's burrow. Notice that he or she has carefully brought in and arranged a fence of cholla buds to protect his home from snakes and other predators. Pack rats are a serious problem for campers in the desert because they like to get under vehicle hoods and chew wiring. I have not had any problems, but many people put strings of lights underneath their vehicles to dissuade them.
I found out that this is a buckhorn cactus. I posted one a few days ago and called it a staghorn, but that is not correct.
As the sun gets low just before it sets, it lights up Slash Mountain in oranges and yellows. I took this photo from my campsite.
Sun has set behind my rig.
I'm headed to Tucson, but will be back here for another ten days in March.
