I posted about a typical Rove at Tohono Chul park in early June. We are now in the midst of the summer Monsoon season, and it has been very humid—very unlike our usual desert weather. Last night it rained two inches in the Park, and this morning it was like a steamy jungle. A lot of plants appeared to have grown overnight. There were lots of blooms, and one major change to a familiar landmark.
All the trails were very eroded—when water flows in the desert, it goes where it wants to go.
Two cacti were blooming—one a saguaro way out of season; the other a fishhook barrel, whose season is just beginning:
Desert senna was in bloom along all the paths, and passion flowers were beginning on a vine outside the Sonoran Springs Desert garden:
The biggest monsoon change of all was across from the Overlook, where we have a beautiful, huge copper boulder showing oxidation to azurite and malachite.The ground was evidently so saturated that the boulder had settled, and a previous small crack had widened, splitting the boulder nearly in half!
I asked our resident geologist what could have caused such a split, expecting a technical geological answer, and she said, “Weathering.”
The little female Desert Spiny Lizard who lives in the small crack in the boulder(on the left of the above photo) didn’t seem to mind that her hiding place had become noticeably wider.
