In the middle of the New Mexico/Texas desert is a place that we’ve all heard of but I’m not sure how many of you have actually visited.
Carlsbad Caverns National Park.
If you’ve been here before then you may reminisce while you go along with your new classmates, who will now know why a trip to this wonder needs to be on their list.
I will tease you with just one photo (to keep your interest) while your ‘Lesson’ is being administered.
Ok, so lets go back to the way,way back (like 265 million years or so) and pretend we’re a couple of water molecules. We’re floating around in a big inland sea that some day will be a desert in New Mexico and Texas. We’re helping our friends Sponge Bob and his buddies form a reef of sponge-like critters, (No Patrick Star, Mr. Krabs, Squidward, or any others… just some spongy-type guys). Unfortunately Sponge Bob and his contemporaries croak. But they become the base for the next generation of Sponge Bobs. This goes on for several million years and it grows into a 400-mile long, horseshoe shaped reef along the coast of this big inland sea.
We’re going to jump ahead some more millions of years, add in some exciting activity from our old friend Mr. Plate Tectonics, who is going to get agitated, throw his chest out, and push this whole sea upwards to the point where its cut off from it’s parents to the west and now is on its own.
This process goes on for millions more years in varying stages, up, down, and sideways forming, unforming, fissures and cracks that let fresh rainwater, and the occasional salt water, penetrate downward through the old remains of Sponge Bob and his friends and relatives. When everybody gets together, the Sulfur Bullies meet the Hydrogen Happenings, sulfuric acid is made, bacteria start to feed, they croak and interact with limestone and eventually we get big caves that rise and fall with the varying sea levels until about 500,000 years ago, they start the process that we all know and love, Chemical Precipitation (dripping water).
Drip, (with a molecule of Calcium)
Drip, (with another molecule of Calcium)
Drip, Drip, Drip,
Pretty soon (thousands of years) we get these incredible formations, Stalactites ( t for top or hold tight) and their relatives the Stalagmites (g for ground or reaching up with all their m for might).
There you have it.
Class dismissed!
And we now get to go on our Field Trip (Yay!!!) but no snacks! (Boo!!!) Because they are not allowed down in the cave for fear of contamination.
You may eat your snack on the bus.
The first aspect that I would like to relay to you is the scale of this experience. It is huge! I have occasionally had our resident Chief Spelunker, Paula the Fearless be strategically placed in a photo for scale. That, and you will notice the stainless-steel handrail in some photos. Look carefully for these items as they too add the much-needed scale for this encounter to be appreciated to its fullest extent.
We chose to walk down the 750 feet of elevation on the trail that is over a mile and quarter long. This depth (for comparison) is about 75% of the height of the Empire State Building.
We did not walk back up.
We did take the high-speed elevator.
When we finally reached the main attraction at the bottom, that of the aptly named Big Room, the path around that was another mile and a half!
Now for all of you Jules Verne fans…. we will start our Journey to the Center of the Earth 😊
The next few photos may, or may not, have any text under them. Some need a comment, others just need someone to see them. That someone is you.
I hope that you have enjoyed your tour of Carlsbad Caverns and can only wish that you may someday visit this incredible place. It is not at all claustrophobic as my lovely assistant, Paula the Fearless, can attest!
