When I was a kid, Cienega Creek was called Pantano Wash (at least by people I was around) through Tucson and east past where it crosses I-10 now (Cienega Creek flowed into it from the south), and Pantano was once a railroad station / tiny town just to the north side of where I-10 is now, near the east end of where the preserve is now. These hoppers were found just to the north a bit from Cienega Creek in a low well-watered area off on a little dirt track, full of lush grass and some native deciduous trees, not many miles from the first sighting in the area, but in a side "mini canyon" of different land ownership. Unfenced and unposted (so far). Never found the hoppers there before, but was never looking before.

Pantano shows on most state maps up to a certain year, then just mysterously vanishes. There used to be Pantano mailing addresses, but I don't know if the postal service even recognizes it anymore (haven't checked). The street in Tucson (if I remember right) connects (connected?) up with the old Pantano Road (now Marsh Station Road) via Old Spanish Trail. Not that many years back it was a graded dirt road; wound through the hills and I think went through the (now) park where the caves are, then on to Cienega Creek (Pantano Wash) and meets I-10 a bit southeast of the site of Pantano (which used to be labeled as the Pantano exit along I-10). Things have changed a lot out there, but Pantano still seems like a good reference point, being the closest with a name. Gee, and I'm not all that old :[

As a side note, this habitat appears to belong to a recently sold private residential lot, and likely it will soon be a home site, or at least a yard, since somebody has started mowing patches of the grass, and is planting more trees. Otherwise it still looks like it did 20 years ago, but apparently not for much longer.

Here is Pantano cerca 1880.

Lots more Trees, Mesquite and Creosote there now. In theory the same spot, perhaps the same water tank?
