This was the highlight and reason for my Southern Arizona Adventure 2024. This is stage 8 of 9.
I was lucky to secure permits for the once monthly photography tour of Kartchner Caverns. Kartchner Caverns State Park strictly forbids any cameras or cellphones in the Caverns. Except for one trip per month for 12 to 15 photographers currently $125. I planned a 4 day 3 night road trip around Southern Arizona anchored by my Kartchner Cavern permit.
I was expecting dark conditions. The State Park turned on all the lights in the Big Room. They don't like turning on all the lights since can this cause an increase in algae. This is the reason they only have one photography tour a month.
I believe that this formation is "Moon Milk." Any correction will be appreciated.
I found myself adjusting my histograms to not clip the highlights. Adapt, Improvise, and Overcome. Next time I am going to bracket my shots. I almost wish I had brought a ND filter or tried a handheld GND filter.
I don't know speliothems so I won't even try to identify. If anyone can help me with the identification, I will appreciate it.

The features that arouse the greatest curiosity for most cave visitors are speleothems. These stone formations exhibit bizarre patterns and other-worldly forms, which give some caves a wonderland appearance. Caves vary widely in their displays of speleothems because of differences in temperature; overall wetness; and jointing, impurities, and structures in the rocks. In general, however, one thing caves do have in common is where speleothems form. Although the formation of caves typically takes place below the water table in the zone of saturation, the deposition of speleothems is not possible until caves are above the water table in the zone of aeration. As soon as the chamber is filled with air, the stage is set for the decoration phase of cave building to begin.
The term speleothem refers to the mode of occurrence of a mineral—i.e., its morphology or how it looks—in a cave, not its composition (Hill, 1997). For example, calcite, the most common cave mineral, is not a speleothem, but a calcite stalactite is a speleothem. A stalactite may be made of other minerals, such as halite or gypsum.
Classifying speleothems is tricky because no two speleothems are exactly alike. Nevertheless, speleologists have taken three basic approaches: classification by morphology, classification by origin, and classification by crystallography. All three of these approaches have their problems (Hill, 1997), so cavers often take a more practical approach that primarily uses morphology (e.g., cave pearls) but includes whatever is known about origin (e.g., geysermites) and crystallography (e.g., spar) when needed.

The Kartchner Caverns, rated one of the world's 10 most beautiful caves, is an eerie wonderland of stalactites and stalagmites still growing beneath the Whetstone Mountains 40 miles southeast of Tucson.
The limestone cave has 13,000 feet of passages and hundreds of formations built over the past 200,000 years, including some that are unique and world-renowned. It's a "living cave," with intricate formations that continue to grow as water seeps, drips and flows from the walls and slowly deposits the mineral calcium carbonate.
The caverns were discovered by amateur spelunkers Randy Tufts and Gary Tenen in 1974 on land owned by the Kartchner family. They kept the cave a secret until 1988, when the Kartchners sold it to the state to become a state park.
The highlights of the Big Room tour are a stretch of strawberry flowstone, which has been colored red by iron oxide (rust) in the water, and a maternity ward for 1,800 female cave myotis bats, with black grime on the ceiling where the bats hang and piles of guano on the floor. Visitors who look closely will see a bat's body embedded in one of the cave's formations.
Though not all are available on the tours, the caverns' unique features include a 21-foot, 2-inch soda straw that's one the world's largest (Throne Room), the world's most extensive formation of brushite moonmilk (Big Room), the first reported occurrence of "turnip" shields (Big Room), the first cave occurrence of "birdsnest" needle quartz formations (Big Room) and the remains of a Shasta ground sloth from the Pleistocene Age (Big Room).

Kartchner Caverns State Park is a state park of Arizona, United States, featuring a show cave with 2.4 miles (3.9 km) of passages.[1] The park is located 9 miles (14 km) south of the town of Benson and west of the north-flowing San Pedro River. Long hidden from view, the caverns were discovered in 1974 by local cavers, assisted by state biologist Erick Campbell who helped in its preservation.
The park encompasses most of a down-dropped block of Palaeozoic rocks on the east flank of the Whetstone Mountains.
The caverns are carved out of limestone and filled with spectacular speleothems which have been growing for 50,000 years or longer, and are still growing. Careful and technical cave state park development and maintenance, initially established by founder Dr. Bruce Randall "Randy" Tufts, geologist, were designed to protect and preserve the cave system throughout the park's development, and for perpetuity.[3]
The two major features of the caverns accessible to the public are the Throne Room and the Big Room. The Throne Room contains one of the world's longest (21 ft 2 in (6.45 m))[5] soda straw stalactites and a 58-foot (18 m) high column called Kubla Khan, after the poem. The Big Room contains the world's most extensive formation of brushite moonmilk. Big Room cave tours are closed during the summer for several months (April 15 to October 15) each year because it is a nursery roost for cave bats, however the Throne Room tours remain open year-round.[8]
Other features publicly accessible within the caverns include Mud Flats, Rotunda Room, Strawberry Room, and Cul-de-sac Passage. Approximately 60% of the cave system is not open to the public.[9]
Many different cave formations can be found within the caves and the surrounding park. These include cave bacon, helictites, soda straws, stalactites, stalagmites and others.[12] Cave formations like the stalactites and stalagmites grow approximately a 16th of an inch every 100 years.[13]
Haiku thoughts:
Beneath earth's cool veil,
Stalactites in silence grow,
Whispers of stone deep.
