First timer? In this formerly once-a-day blog (and now pretty much a once-a-week blog) I use an app that provides a random latitude and longitude that puts me somewhere in the continental United States (the lower 48). I call this “landing.”
I keep track of the watersheds I land in, as well as the town or towns I land near. I do some internet research to hopefully find something of interest about my landing location.
To find out more about A Landing A Day (like who “Dan” is) please see “About Landing” above. To check out some relatively recent changes in how I do things, check out “About Landing (Revisited).”
Landing number 2553; A Landing A Day blog post number 998
Dan: Today’s lat/long (N32o 21.736’, W111o 35.754) puts me in South Central Arizona:
My local landing map shows that I landed in the middle of nowhere, presumably in the desert. (For reference, it’s 46 miles from Anegam to Marana.)
Zooming back a little, you can see that I landed not far from Tucson (actually a little less than 40 miles):
As generally happens when I land in the desert, I had to go to Google Earth (GE) to figure out my drainage situation. Here’s an oblique shot looking east that shows I landed near some clear west-bound drainageways:
I expanded my view, engaged the GE hydrographic features app, and managed to figure out my watershed analysis. And let me tell you, the following GE shot took a lot of work:
So. I landed in the Aguirre Valley Wash; to the Kohatk Wash; to the Santa Cruz Wash; to the Santa Cruz River (2nd hit); to the Gila R (44th hit).
I’ll head over to my streams-only Street Atlas map, which doesn’t even bother connecting the Gila to the Colorado (I had to add it in):
This is the 194th hit for the Colorado. [ALAD Obscurus side note: The Colorado River is slightly undersubscribed: based on the ratio of the basin area (not including the Mexican portion) to the area of the lower 48, I should have 200 landings in the Colorado basin.]
Speaking of the Gila not being connected to the Colorado, here’s a short Wiki piece that I lifted from a recent (July 2021) ALAD post:
In 1944, 25 German prisoners of war pulled off the largest and most spectacular escape from an American compound, digging a 178-foot tunnel out of the Navy’s Papago Park Prisoner of War Camp (near Phoenix). All of the men were eventually captured, though some remained at large for more than a month.
Among the last to be captured were three German soldiers who had based their audacious but ill-fated escape plans on a stolen highway map of Arizona, which showed the Gila River leading to the Colorado River, which in turn led to Mexico. Devising a scheme to flee by water, the Germans constructed a collapsible kayak under the noses of their American captors, tested it in a makeshift pool within the prison compound, then sneaked it out through the tunnel. Their plan was perfect – except for the map. The Gila, shown as a healthy blue waterway, turned out to be little more than a dry rut.
The Orange Dude figured out that he could get a look at the Kohatk Wash:
There’s not much to see in terms of the Wash, but the OD positioned himself to look across the Wash at some scenic topography:
The OD and I had very low expectations about getting a look at my landing spot. But as I was perusing GE, I noticed Kitt Peak (home of the Kitt Peak Observatory), about 25 miles to the south of my landing. I then realized there was no obtrusive topography between Kitt Peak and my landing! The OD was on it:
And here’s what he could see:
And then I had one of those JFTHOI moments: I’m not sure exactly how I stumbled on this GE shot, but it’s kind of cool:
Before I visit my titular towns, I need to mention the ugly scar on the landscape, just east of my landing. It’s the Silver Bell copper mine:
It’s still active, although producing copper at much lower levels than it used to. I found this back-in-the-day (1910) shot of the company town near the mine:
It’s time for Eloy. From the Eloy city website about the name origin:
Southern Pacific Railroad built the first railroad across Southern Arizona in 1878/1880. It was known as the East Line of Yuma. In 1902 they added a siding and section house six miles west of Picacho and named the siding Eloy, the acronym for the East line of Yuma. During construction of the railroad it was easier, and faster, to handprint E.L.O.Y. on construction drawings, maps and crates of materials.
Well, OK, I guess. “East Line of Yuma” is peculiarly worded. I would expect “Yuma East Line” or “Line East of Yuma.” Whatever . . .
Moving over to Arizona City. From Wiki:
The area around what is now known as Arizona City was used as a resting area for Juan Bautista de Anza’s expedition party after they emerged from Apache land in 1775. The area is considered an official part of the Juan Bautista de Anza National Historic Trail. This historic trail begins in Sonora, Mexico, and ends at the Presidio in San Francisco, California.
Juan was born in Mexico in 1736, the son of a wealthy military leader. He ended up being famous for leading the expedition that founded various Catholic Missions in California and established trade routes between Mexico and California. Here’s a map of his trip:
I’m not very excited about my first two towns – East Line Of Yuma & some dude who went from Mexico to San Francisco. Likely you join me in a similar mindset. All righty then. Casa Grande, it’s up to you to rescue this post from mediocrity.
The town of Casa Grande is named after the Casa Grande ruins, a remnant of the Hohokam culture that flourished from about 500 CE to 1450 CE. (CE is “Common Era.” It’s the secular version of AD, and is now generally used in scientific writing). Here’s a GE shot of the ruins, which are part of a 200’ x 400’ compound (a protective roof was built over the main structure in 1932):
The National Park Service (NPS) website for the ruins has this artist’s rendition of the compound as it may have looked in 1350 CE:
Here’s a picture of the Casa Grande, from the NPS website:
And a Wiki shot of the building in 1890:
This shot of ruins within the compound was posted on GE by DS Anderson:
Here’s some verbiage from the NPS site:
Archeologists have discovered evidence that the ancestral Sonoran Desert people who built the Casa Grande also developed wide-scale irrigation farming and extensive trade connections which lasted over a thousand years until about 1450 CE. Archeologists recognize the culture (known as Hohokam) by its geographical area, its adobe buildings, distinctive pottery, and extensive canals. Note that this is not the name of a tribe, and should not be confused with the ancestors of the O’odham, Hopi, or Zuni people.
From Wiki:
The Hohokam cultivated varieties of cotton, tobacco, maize, beans, and squash, and harvested a vast variety of wild plants. Late in the Hohokam Chronological Sequence, they also used extensive dry-farming systems, mainly to grow agave for food and fiber. Their agricultural strategies were vital in the inhospitable desert, and allowed the aggregation of rural populations into complex urban centers.
In modern-day Phoenix, the Hohokam are recognized for their large-scale irrigation networks. Their canal network in the Phoenix metropolitan area was the most complex in ancient North America. A portion of the ancient canals has been renovated for the Salt River Project and helps to supply the city’s water. The original canals were dirt ditches and required routine maintenance; those currently in use are lined with concrete. When Hohokam society collapsed, the dirt canals fell into disrepair. Some European-American settlers later infilled some canals, while others renovated and used them.
I found a scholarly article on the decline of the Hohokam culture, from archeologysouthwest.org. Here’s an excerpt:
Was it a Catastrophe…
Archaeologists used to believe that Hohokam population decline happened quickly and was caused by some type of catastrophe, such as flooding, disease, or warfare.
…or was it Coalescence?
If population decline did not result from a single catastrophe, understanding why it happened is more complicated. Archaeologists now believe the region experienced a gradual, centuries-long process of population decline. Archaeology Southwest researchers explain this region-wide decline through the Coalescent Communities model.
Gradual Population Decline: The Coalescent Communities Model
As immigrants arrived on the edges of the Hohokam region, local groups began coming together (coalescing) into fewer, larger communities, which caused economic, ecological, and social changes. One result of immigration was increasing social tension. More defensive site locations were chosen and use of small, scattered farm sites was discontinued. People increasingly focused on cultivation of a few crops in irrigated fields, and discontinued more dispersed forms of agriculture and the use of wild foods.
Dependence on irrigated crops diminished diet and health. As people grew a smaller range of foods, they were more vulnerable to environmental degradation and flooding, making farming increasingly difficult and risky. At the same time, as they began to live in more concentrated settlements around irrigation canals, increased contact among people in crowded settings, the challenges of waste disposal, and standing water increased the risks of disease.
The end result: a gradual population decline that resulted in a societal collapse. Ouch. At least it had nothing to do with the coming of the white man . . .
The Indian tribe that is most native to the area is the Tohono O’odham. It seems to me at least likely that members of this tribe are related to the Hohokam culture. I found this piece of 1960s absurdity in Wiki about the Tohono O’odham:
In 1960, the Army Corps of Engineers completed construction of the Painted Rock Dam on the Gila River. Flood waters impounded by the dam periodically inundated approximately 10,000 acres of the Gila Bend Tohono O’odham Indian Reservation. The area lost by the tribe contained a 750-acre farm and several communities. Residents were relocated to a 40-acre parcel of land named San Lucy Village, near Gila Bend, Arizona.
AYKM? And it took until 1986 to do anything about it:
In 1986, the federal government and the Nation approved a settlement in which the Nation agreed to give up its legal claims in exchange for $30,000,000 and the right to add up to 10,000 acres of newly purchased land to its Reservation.
On that uplifting note, I’ll move to close out this post. I found a cluster of photos posted on GE by one Jonathon Berman, just east of my landing:
And here they are:
I’ll close with this shot, not part of the cluster of photos shown above, but still one of Jonathon’s. This was taken down near where my very local drainage runs into the Aguirre Valley Wash.
He was looking east, and my landing is actually visible on the photo! I didn’t want to mar his photo, so I made a copy and added my landing spot:
That’ll do it . . .
