About the trip

    In March I traveled in Arizona, a state I had not visited since 1966.  The Grand Canyon State is America’s second fastest growing, after Nevada; and most of its people live in one of four big cities (each among the country’s largest) or their suburbs. It  has over 5 million inhabitants. But averaged across its huge land area, this is only 45 people per square mile, about the same as Maine!  So there are still many wide open spaces with great natural beauty.

   Our afternoon flight moves west over an unbroken layer of clouds. But around Arkansas breaks begin to appear in the clouds below and the sky ahead opens up.  The southwest horizon is colored in blazing rose and slate gray. Minutes later the sun is setting beyond the nose of the plane.  Beside us the Band of Venus, the projection of the Earth’s shadow back into the atmosphere, becomes clearly visible. It appears as a band of blue a couple of shades darker than the sky and looks almost like a giant storm is coming,  just below a similarly projected, but thinner line of dark sunset pink. Exactly to my left I see the point of inflection – I’d never seen this before from ground level – where the Earth’s shadow appears to emerge from. As sunset progresses the shadow casts higher and I see it cast the highest ever in my experience, until it merges with the general dark blue of the evening sky after a few more minutes -- a gift of airplane flight.

Spring Journey
   March is spring in southern Arizona and the desert is in bloom! Nature conducts her business in dry climates almost the same way as in wet ones. The countryside is filled with a complete set of watercourses, just like here in Maine -- save for being mostly dry until called on to carry the sudden massive desert downpours.  Although it is often cloudless in southern Arizona, sometimes there are scattered cirrus. On occasion it is overcast and may or may not rain. But rain can come, often suddenly, from rapidly moving cumulonimbus clouds, too.
   The landscape is nearly covered with plants, except that they grow in a more vertical, water-conserving way, whereas ours in Maine can spread out laterally to make the best use of the lesser sunlight.  The expansiveness of the spring bloom depends on a number of factors, especially the amount of rain in early winter. In some years the wildflower display can be quite spectacular.

A walk on the dry side
   In McDowell Sonoran Preserve we walk on a trail that soon descends into a wash (dry, flat watercourse). The stream channels are currently dry. I look for any signs of long-lingering moisture, and we do actually find moss below some bushes down in the bottomland.  Wildflowers are not all in full bloom yet, but lupine, desert poppies and other low plants and some of the cacti are in flower.  We also see small lizards and a grasshopper.   Many saguaros have round holes about 4 to 7 inches in diameter.  I never saw any birds enter the cavities in the cacti, but occasionally see birds perched on the tops.

Grand Canyon
   On the way to the Grand Canyon the habitat zone shift is dramatic and exactly as my biologist daughter had outlined for us.  Driving north the increasing latitude also brings increased altitude: 
     ·  Tall saguaro; desert plants; dry (1500’)
     ·  Short saguaro; prickly pear; desert plants; still very dry (2500’)
     ·  Juniper, prickly pear predominantly (3000’) 
     ·  Sagebrush; some woody plants (4000’) 
     ·  Arid again, high plateau with cattle grazing (5000')
     ·  Ponderosa pine; creeks with flowing water; a transition zone (6000’)
     ·  Thicker forests; pines; some snow (7000’)

  At the Grand Canyon we get advice from the Park Information Desk and decide that the South Kaibab Trail is the least icy and treacherous. Ice remains long in trails in the South Rim because most parts are north-facing. 
   The Sun had penetrated enough in the highest altitudes of the trail so that it is manageable. The trail is not quite as scary as we had thought. The footways on the Park trails are usually fairly wide (6 or 8 feet), decently graded, and sloped away from the precipice. The gradualness of the slope is to accommodate pack animals.  Usually there is a solid cliff wall to one side to concentrate on, instead of the 2 or 3 thousand foot drop on the other side!
   In only a very few short places is there a dropoff on both sides. After a while we get accustomed even to that, and gain confidence. The only really hairy part is the beginning where remnant ice, covered with mule dung, made for delicate footwork (although I suppose the mule dung helped too, by darkening some of the ice and speeding the melting).
   We don’t descend all the way to the Colorado River – just to Cedar Ridge, elevation 6060 feet, about 1100 feet down, where we stop for lunch. There are hitching posts there – showing that animals would be led or ridden later in the season. We see ravens and two Western scrub jays. My wife sees a California condor. Though rare, there have been releases of these giant birds into the wild from the North Rim, and we are confident this was one of them. I identify a chickadee by song.  But it must be a western species, as its song is noticeably slower than that of our black-capped chickadees.

Sedona and Oak Creek Canyon
    On the drive back we take the “scenic” route, a long, mountainous descent on a spectacular road that descends the Oak Creek Canyon, a mid-sized version of the Grand. Twisty turns, switchbacks and steep dropoffs all add to the drama (and barely controlled terror) of the ride down to Sedona from Flagstaff. 
   An interpretive sign says that flora and fauna from three habitats can be found in the unique valley formed by this particular canyon due to the varied altitude and soil types, and its North-South orientation: desert, semi-temperate, and water-loving.  It is almost homelike in the bottom half of the drive, as we are surrounded by fairly tall tees and shrubs which hug the banks of Oak Creek, freely flowing with actual water in it!  We remark that it was like a New England gorge.
   The backdrop of the city of Sedona is a group of some spectacular red-rock mesas. 

Lost Dutchman State Park
   We camp in Lost Dutchman State Park one night.  It is named for a successful gold miner from the Netherlands who eventually disappeared, along with all knowledge of the location of his big find.  The place is full of mystery.  For our evening walk we make it up part way up the slope of the red-rock Superstition Mountains in the Tonto National Forest behind and adjacent to the state park. They virtually shine in the pre-sunset alpenglow.  Big rock formations with imaginative names, e.g. Praying Hands, Green Rock, and Flatiron look down on us.
   Returning later we are rewarded by the celestial sights. Despite the great light-loom from metro Phoenix, we see five visible planets: Mercury, Venus, Mars, Jupiter and Saturn.  The late evening desert quiet is welcome after the noise of the city.

Peralta Trail
    The hike in Tonto National Forest up to Fremont Saddle (3640') in the Superstition Mountains, is a very lovely desert experience, and a highlight of the trip, despite the record-breaking late March temperatures (about 93° even up high).  The bottom half of the trail follows Peralta Creek.  The flora along it are fascinating.   It is incongruous to see running water in the desert trailside.  We are grateful that this mountain stream offers occasional and welcome cooling splashes.  Halfway up, its flow disappears below the surface. On the way we hear crickets, see a family of partridges – or similar birds – crossing the trail, and see water-striders in the pools of the creek.  
   An unanticipated benefit of this trip is that I finally get to see back roads and a sample of the back country, a side of Arizona that I had been seeking.

Boyce Thompson Arboretum State Park
   We visit an elaborate arboretum near Superior, Arizona which offers a great walk, and the sight of many, many labeled species of trees,
shrubs, and cacti, all in their various respective environments. The highlight is the second half of the walk where we descend among rocks to a creek and enter a desert riparian environment both planted and unplanted.

Catalina State Park
   One night we camp in a beautiful park at the
foot of the Santa Catalina Mountains.  We hear crickets, just a few, singing slowly, about 2 chirps per second.  Following the rule of subtracting 45 from the number of chirps per minute, it comes pretty close to the actual temperature of 73°!   We see a bat fly over, the second seen on this trip, and are glad to have her catching the few mosquitoes around. An owl calls softly "Hoo-hoo.  Hoo-hoo-hoo-hoot?"
   In the morning we climb up into the Coronado National Forest, home of mountain sheep and mountain lions.  We see neither, but encounter lizards who seem genuinely curious about us and do not flee at our approach. (They are not poisonous).  On the Romero Trail we go way up and encounter pools in a high mountain stream -- a  good place to stop for refreshment.
   After we leave the Park we head down to Tucson.  Along the way we see big irrigated fields, some already vivid green with a low dense crop.  We're told it could be soy or cotton.  Other fields are tilled but are still bare earth. In other places  there are plantations of trees, each about 20'-30' high, in neat rows. I guess that they are nut trees and a local person confirms they are most likely pecans. 

Some stories
    Here is my initial and lasting impression from our first morning:  it is the birds!  The sound of birds, plentiful and rich, is unexpected, but so welcome.  My notion of the desert was that it is totally silent, but I  am happily proved wrong.   That morning I see a black bird of the shape, color and size of a crow, but his calls and songs are all musical and uncrowlike. It is a magpie!  Also there are mourning doves, chipping sparrows, and mocking birds. We hear a call or song that was familiar to
me from the bird song tapes, but I couldn’t quite place it. My daughter identifies it as a woodpecker, probably a flicker...

    In the early evening while we are camped in Catalina State Park an emergency vehicle's siren is heard wailing in the distance. Soon another, but puzzling sirenlike sound is heard from the woods behind us.  After a couple of minutes the vehicle is closer on the distant highway and again sounds the siren, which is much more audible.  It is answered by yips, howls and wails. Now I'm catching on to what is happening. One last time, much clearer and louder the siren goes by. It is hilariously  answered by what appears to be two separated packs of coyotes having a rip-roaring old time. A yowling party erupts that lasts a couple of minutes...

   The palm trees seen growing in the cities are all non-native transplants!  I am reminded of  the stereotypical desert oasis scene, and that makes it seem more credible:  they need heat AND water.

Dialects
    The mockingbirds look like mockingbirds, and sing like mockingbirds (giving the customary 3 or more repetitions of each song phrase that distinguishes them from other imitator birds).  But their songs are almost all different from the ones in Maine.  I guess they are sort of avian tape recorders, and thus are rendering the birds' version of the local hit songs!  

A vision of the past
   We visit Casa Grande Ruins National Monument.  There are remains of  two- and four-story wattle and adobe buildings.  They are not cliff dwellings, but self-standing structures in the middle of the desert.  The occupants left suddenly around 1400 AD.  Archaeology shows they had a thriving community life and grew bountiful crops of squash, beans and other legumes.  They had dug wells to depths no greater than 10 or 12 feet, where they found reliable water in those days.  Now the water table is 100 feet or more down!  Climate change?  The modern drawdown from Arizona's great and thirsty cities? 

Back home
It's odd to say, but when I returned to Maine and thought about all the new and curious things I had seen and heard, the feeling of strangeness  mostly subsided and I was left with a sense of familiarity.  It was as if Arizona would welcome me back.
