They may not actually have much in common, but there is a common thread — Salt constitutes a ribbon of continuity from ancient times to the present, and beyond. It is essential for life. Luckily, salt in its various forms is abundant on earth. Processing techniques have been employed for millennia, and salt as a commodity was once prized as much by nations as by individuals.
Today, the love of salt extends to specialty varieties, including Himalayan sea salt, black salt, Celtic salt, smoked salt, and rare, expensive Fleur de Sel from Brittany, among others. Every type of salt has its dedicated advocates.
But who knew that pretzel salt comes from a small East Texas town?
It’s true. Every pretzel consumed all across the United States has salt crystals extracted from the massive salt dome situated deep below the Texas prairie about 75 miles east of Dallas.
Salty Travels and Tales
I had heard of Grand Saline, but I never — ever — gave its name much thought until I learned last year that it has been the home of a Morton Salt mine for nearly a century.
In the mid-1990s, I had the privilege of visiting the planned nuclear waste repository (WIPP Site) near Carlsbad, N.M., prior to the time it received its first shipment of radioactive waste. I treasure a large chunk of salt that I brought up from that salt cavern almost half a mile underground. Now I also have two small rock salt crystals extracted from below the earth’s crust in Texas. They are much harder; and they are clear.
I also remember sailing around Salt Island, in the British Virgin Islands. My companions and I didn’t dive the wreck of the Rhone, nor did we step ashore on the island, but we were enthralled to learn that current inhabitants still pay an annual rent to the Queen — a one-pound bag of salt. Traditions die hard!
Then, just a year or so ago, I visited Ston, a small town in Croatia, where salt has been harvested from the shore of the Adriatic for centuries. Of course, I brought home a bag of Croatian salt. I regularly buy unusual salts at the grocery store. We enjoy cooking with them, and sampling the various textures and flavors.
In addition, my husband and I were recently gifted with a beautiful book, “Salt,” by Mark Bitterman, along with a Himalayan salt slab, designed for grilling; it is supposed to embue meats and vegetables with natural salty flavor. We are eager to test it!
So, it was with a sense of expectation that we took a day trip recently to Grand Saline. Its history extends back in time to about 800 BC, when the local Caddo Indians collected salt from surface marshes. Those same drying flats supplied Confederate soldiers with salt during the Civil War.
The salt flats still exist on the mine property, but are no longer publicly accessible. But evaporative salt is still processed in much the same way, although on a much larger scale than formerly.
To my disappointment, tours of the mine itself were discontinued, because of federal (OSHA) safety regulations, in the 1960s, but visitors to Grand Saline can learn the history of the mine through exhibits and a 14-minute video at the Salt Palace, a funky little building right in the heart of town. It actually boasts salt block siding, but licking it is not really encouraged!
About that Pretzel Salt
The underground salt dome, said to extend downward at least 20,000 feet from the surface, is vast. It is said that this single salt deposit could supply this country’s needs for many thousands of years. At a level 750 feet below the surface, where mining operations take place today, the salt dome measures approximately 1.5 miles in diameter. The “mother bed” of salt is said to be a remnant of an ancient sea. Underground temperature is a constant 75 degrees.
Each underground salt “room” is about 75 feet wide and 25 feet high, with solid salt pillars for support that measure 130 feet square. Future expansion will enlarge existing rooms to 75 feet in height from floor to roof. Trucks and all mining equipment are brought from the surface in pieces and reassembled in the mine. Approximately 100 miles of roadway wind through the caverns, and mining operations continue underground 24 hours a day, seven days a week.
The salt deposits are 98.5% pure NaCl. Grand Saline is one of only two Morton Salt plants to produce both rock salt and evaporated salt; it produces all major grades of evaporated salt, including dendritic (flaked) salt, and is the company’s sole producer of shaker products and salt substitute potassium chloride.
Salt, of course, is not just for eating. Because of its purity, the salt extracted from the Grand Saline mine is also earmarked for pharmaceutical use. Salt is, after all, salt — but what is taken from the earth at Grand Saline mine is deemed unsuitable for most industrial uses because it is too pure. Although it could be used to melt snow, that would, in effect, seem wasteful!
Our visit to the Salt Palace was enlightening. Poking around Grand Saline on a beautiful early spring day was pleasant, although there’s not much there other than the Salt Palace. But it’s an easy day trip from Dallas or Fort Worth, and it’s always fun to get out on the back roads; you never know what you might find!
I will never again take salt for granted, but will instead savor the many varieties that are available. And, for sure, I’ll continue to collect salty stories.
