Lots of cactus today and also a little of some heavenly bodies. We drove up to Kitt Peak and took one of the guided tours.

 After our tour and a peek at the 2.1 meter scope, we stopped by the solar observatory to take a look at some spots on the sun.  This is funded by the NSF and astronomers can submit proposals for use.  There are dorms for people using the observatories to stay while there.  Only 3 public scopes are there for viewing.  The rest, and there are several on the top of this mountain, are from other Universities.  CU has one here. 

 We have a nice picnic lunch before drove the 12 mile road back down the mountain.

 This part of Saguaro is on the west side of Tucson called the Mountain district.  Tomorrow we are visiting the Rincon Mountain side east of Tucson before driving up to Mount Lemmon for our nightly observation tour.

 Here some the cactus

 Look at this big boy.

Prickly pear ready to sprout.
