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 2535; A Landing A Day blog post number 980
Dan: Today’s lat/long (N28o 48.818’, W99o 29.733) puts me in south central Texas:
Here’s my local landing map:
I know, I know – I usually highlight my titular towns on my local landing map. Well, you’ll just have to find them yourselves . . .
Let’s move over to Google Earth (GE) to get a look at my landing. The Orange Dude couldn’t get as close as he’d like:
Here’s what he sees:
He couldn’t help but notice that he landed in a huge oil field:
Here’s a close-up of the circled white rectangles:
And closer still:
Yup. No question. It’s an oil field. We’re looking straight down at a pump jack which is casting a wonderful shadow!
Let’s zoom back, and label some waterways:
I landed in the watershed of the Leona River (2nd hit), on to the Frio R (5th hit, making the Frio the 176th river on my list of rivers with 5 or more hits).
Zooming way back (and moving over to StreetAtlas):
The Frio runs parallel to, but eventually discharges into the Nueces, which flows into Corpus Christi Bay.
JFTHOI* I’ll personify the Frio River: “It’s so not fair! Two sizable rivers come together, and they (the river-namers) could have decided that the Nueces flowed into the Frio, and the Frio was the river that went to Corpus Christi. But noooo. And my name is so much easier to pronounce!.
*Just for the heck of it.
I sent the Orange Dude a little east of my landing to get a look at the Leona River:
Here’s the I-can-always-count-on-the-Texas-DOT sign:
But trying to see the Leona River itself? Not really:
I think I’ll start with Big Wells. Let’s guess how the town got its name:
- The Wells brothers were early settlers. The older one was wealthier and more important than the younger – not to mention he was much larger. They wanted to name the town “Wells,” but the older brother insisted on a way to differentiate the brothers.
- Some wildcat oil wells were huge producers; or
- Water wells were huge producers
Even though the third bullet seems like a weak third, that’s the correct answer! From TexasEscapes.com:
The name doesn’t seem to have been an exaggeration when the town was founded. It was named for the artesian wells that once (allegedly) jetted 30 feet into the air. Naturally with this abundance of water – it was a prime location for land developers. There were several development projects in Dimmit County (including Big Wells) between 1909 and 1917.
The artesian wells that gave the town its name have required pumps to produce water since the mid-1940s.
As a geologist who specialized in groundwater (more technically known as a hydrogeologist), I’m fully aware of what’s going on in an artesian aquifer. Class, may I please draw your attention to this figure:
The tan-colored unit is sandy – i.e., water can flow through this unit fairly easily. This kind of unit is called an aquifer. The gray units – labeled “confining bed” are clay beds. Obviously, water cannot flow through the clay.
The little horizontal lines in the well casings signify the “well screen,” which is simply where slots in the casing allow water to flow into the well.
The little triangles signify the “water table.” If one digs a deep hole, the water table is the depth where water starts to flow into the hole.
An “unconfined aquifer” is where the aquifer actually contains the water table. A “confined aquifer” is a sand unit that has a confining bed above it. A confined aquifer does not contain the water table.
The dashed line is labeled “potentiometric surface” which sounds complicated but really isn’t. In an unconfined aquifer, the potentiometric surface is the same as the water table. In a confined aquifer, it’s the level that the water in a confined aquifer would rise to in a well that’s screened in the confined aquifer.
The “Recharge Area” is where infiltrating rain water can actually find its way into the confined aquifer – where the sand unit is located at the land surface. See the water table at the recharge area? That’s the beginning of the potentiometric surface for the confined aquifer.
So as we go to the right, the first well we run into is labeled “Flowing Artesian Well.” It’s flowing because the potentiometric surface for the confined aquifer is actually above the land surface. This is like the original wells in Big Wells. If the casing extended up above the land surface, the water in the well casing would be at the potentiometric surface.
You can see the “water table well,” which by now should be self-explanatory. You can also see the “artesian well.” It’s called “artesian” because the water level rises above the confining unit. It’s not “flowing” because the land surface is higher here.
As is my wont, I’ll guess as to my readership’s possible responses to this geology lesson. Here are my response categories:
- Blurred over right away, started skimming.
- Gave it the old college try, but really didn’t care enough to pay close attention.
- Spent some time on it, but wished you didn’t.
- Spent some time on it, and are glad you did.
- Took one look at the figure, and knew right away how the entire system functioned.
Sorry class, I’m not done yet. I checked out the area around Big Wells, looking for the recharge area, which must be at a higher elevation than the land around Big Wells. Here’s what I found:
I don’t know for a fact that the recharge area is the area just south of my landing with the higher elevations. The geologic strata (i.e., the aquifer and the confining bed) would have to line up pretty much like it’s shown in the above schematic. But if I were a betting man, I’d say that my guess is correct . . .
Moving on to Crystal City. First of all the name: it’s for the crystal-clear water that came gushing out of the artesian wells near the town. It seems to be a regional phenomenon . . .
Here’s a picture from TexasEscapes:
And another:
If you are too young to know who Popeye is – and his associated with spinach, just Google it.
And yes, Crystal City is known as the “Spinach Capital of the World.” Evidently, someone decided that all of the water gushing out of the artesian wells could be used to irrigate spinach.
If you (like me) guessed that there must be an annual Spinach Festival, you would be correct.
The Texas State Historical Association has an entry on the “Crystal City Revolts.” Here’s a little of their write-up:
In 1963 and again in 1969, Mexican Americans in Crystal City [who have long been a majority of residents] organized against Caucasian domination of city hall and the public school system. The result was an electoral victory for Hispanic Texans for the first time since the city’s incorporation in 1910.
The 1963 movement was led by Juan Cornejo, a local representative of the Teamsters Union at the Del Monte cannery in Crystal City. Cornejo succeeded in getting more Mexican Americans to pay the poll tax and vote.
[Oh my! There was a poll tax. That’s one way to keep poor people from voting.]
In addition, the Mexican Texans organized the large migrant farm-labor pool affiliated with the Teamsters at Del Monte. The Hispanics selected a slate of five candidates, who became known as “los cinco,” from among the poor and undereducated Mexican Texans, to run for the city council.
The group faced intimidation by the political establishment. Several workers at the Del Monte plant were fired for wearing campaign buttons, for instance; but Teamsters officials intervened, and their jobs were reinstated. Del Monte went into overtime production to keep workers from voting. Los cinco, however, gained widespread support, and all five candidates defeated the five incumbents in a close election.
I found a whole series of photos (from Picryl.com) concerning spinach harvesting and shipping from LaPryor (which, by the way, was named after Col. Pryor). The photographer was Russell Lee. Picryl says this about Lee:
In the fall of 1936, during the Great Depression, Lee was hired for the federally sponsored Farm Security Administration (FSA) photographic documentation project of the Franklin D. Roosevelt administration.
These pictures were taken in the early 1940s. I’ll start with some shot of workers in the spinach fields:
Here’s a truck where they’re unloading empty baskets:
Gathering up the full baskets:
And here, a truck is pulled up to a loading platform:
Women workers going to the fields:
A truck full of male workers:
Breaking up ice before icing the spinach for shipment by rail:
Icing down the spinach at the rail car:
Back to now. I’ll finish off this post with a couple of shots posted on GE near my landing. First this, by Crissy Chavira:
I’ll close with this strange, eerily-lit shot by Ramon Palacios:
That’ll do it . . .
