Journey inside Colossal Cave – Arizona’s dormant cave

Before entering Colossal Cave it was essential to educate ourselves and obtain some “cave basics”.  The facts and information we learned about limestone caves made our trip profoundly interesting!

Colossal Cave is an archaic KARST CAVE (meaning erosion has produced fissures, sinkholes, caverns and underground streams).

Colossal Cave is a Karst cave
Karst region

Karst caves have 3 categories:  limestone, gypsum and quartzite.

Colossal Cave is limestone and considered dormant, “dry”.  A dry cave is without drips of water, streams or pools.  How was the cave formed?  Here is a short, simple answer:

  • Precipitation mixes with carbon dioxide from the atmosphere and decaying organic material in the soil.
  • When Carbon dioxide is dissolved in water it forms carbonic acid. The carbonic acid begins to form holes in rocks, seeps into crevices and dissolves the rocks, especially limestone; but very slowly.  (Thousands of years)
    rock crevices and joints.
  • Cavities form and further sculpting can occur from water and chemical weathering.
  • After passing through limestone, the acid water contains a dis-solvable calcium carbonate.  As this solution de-gases through exposure to air by way of splashing, dripping or flowing, it loses carbon dioxide and deposits a solid mineral called calcite.
  • Calcite is the main mineral component in CAVE FORMATIONS, (speleothems).
Calcite, which gets its name from “chalix” the Greek word for lime, is a most amazing and yet, most common mineral. – See more at: http://www.galleries.com/Calcite#sthash.7JQ91AJ6.dpuf

The SPELEOTHEMS in Colossal Cave no longer grow. This cave formed by water depositing limestone that has NOW disappeared.  Close by, in the same mountain park, are Arkenstone and La Tetera Caves with active growing formations.

crystallized calcium carbonate formations

The most abundant mineral in limestone is calcite (calcium carbonate).  The majority of limestone formed on ANCIENT ocean floors.

Calcite is a main component used by echinoderms, like sea urchins, starfish, and sand dollars to make their spines and skeletons.  Calcium carbonate (calcite),  is found in the shells of marine organisms and truly is one of the MOST abundant minerals on earth!

In the marine environment, if the conditions are right, calcite is stable enough that it can cement together sediments and overtime make limestone.

limestone towers in the Atlantic ocean

On occasion another element may be present while calcite is being formed (ex: magnesium) and take the place of a calcium atom.

A less stable aragonite is a polymorph of calcite. They are both calcium carbonate but have different crystal shapes and symmetries.  The calcium, oxygen and carbon atoms in aragonite bond together differently creating a unique crystal structure.

Ok this is plenty of background information so now journey with us to Colossal Cave Mountain Park!

Most crystals are found in areas, like caves, because they take thousands of years to grow.  The growth continues until the saturation is stopped or the cave dries out.  Most crystals in a cave are calcite or aragonite.

Your tour guide will tell the story of the bandits who hid out in Colossal Cave.  These outlaws even played cards in the Colossal Cave Living Room. Legend has it that the gold from the train robbers is still inside the cave!

Stay with the tour group.  Our guide really wasn’t kidding when she said the group might go left and you’ll go right and be lost for hours in Colossal Cave.

Tectonic activity is noticeable.  Your guide will point out a fault in the earth’s crust.

Cave’s formations, speleothems, are created by the same water that dissolved the calcite in the limestone —- then deposited the calcite in other areas of the cave.

When does Monsoon season start? What causes Monsoon?

The official start date of the Arizona Monsoon season is June 15.  In 2008, the National Weather Service determined the AZ Monsoon starting date along with the ending date of September 30.

Tucson Phoenix Monsoon weather
storm clouds Monsoon season

What causes monsoon?

Traders sailing the Indian Ocean and Arabian Sea used the word monsoon to describe a system of alternating winds which blow from the northeast during the northern winter and from the southwest, during the northern summer. Therefore, the term monsoon refers solely to a seasonal wind shift, and not precipitation.

Mexican monsoon cloud
Arizona Mexico Border storm clouds

Arizona happens to be located in the area of the United States that experiences a monsoonal circulation. During the summer months, winds shift from a west or northwest direction to a south or southeasterly direction.

Monsoon weather for Arizona
Microburst clouds during Monsoon

This wind shift allows moisture from the Gulf of California and the Gulf of Mexico to stream into Arizona.  A monsoonal circulation produces a radical change in moisture conditions throughout the entire state.

Arizona thunderstorm dark clouds
Monsoon storm clouds over Coronado Mountains

Thunderstorm or cumulonimbus clouds are very familiar during monsoon season.  These storm clouds cause lightning, hail and heavy rain.

Arizona desert Monsoon Storms
dark thunderstorm burst clouds

What Arizona experiences during the summer months is only a small part of a larger circulation that encompasses much of the southwestern United States and northwestern Mexico. Thus, it sometimes is also known as the Mexican monsoon. The National Weather Service calls it the North American Monsoon.

microburst monsoon storm cloud
Monsoon clouds Mexican Arizona Border

This adjustment in wind direction is the result of two meteorological changes:

  1. the movement northward of the huge upper level subtropical high pressure system, known as the Bermuda High,
  2. and the intense heating of the Mohave Desert creating rising air and surface low pressure, called a thermal low
severe dark thunderstorm cumulus cloud
Monsoon Storm clouds on top of mountains

The southerly low-level winds help to bring in moisture from Mexico. When this moisture encounters the higher terrain of Arizona mountain ranges, it gets lifted and forms thunderstorms.

dark storm Clouds on arizona border
Monsoon storm Coronado Mountains

Small driving factors such as: atmosphere interaction, land elevation, soil moisture and vegetation all play a part in what drives the Arizona Monsoon; but it is also why predicting storm intensity is so difficult.

When such high volume rain descends upon the Arizona desert the ground and the surface streets flood. Quite often the rain pools on streets during monsoon storms causing dangerous driving conditions.

cumulus thunderstorm cloud
Storm burst clouds at Arizona Mexico Border

The monsoon circulation does not produce thunderstorms every day during the summer months, but rather monsoon storms occur in a pattern known as “bursts” and “breaks”.

best Microburst storm cloud photo

This cycle of bursts and breaks will continue from the onset of the monsoon (typically June), until the time when cold fronts begin to move across the state of Arizona (typically September), which will return our winds to a westerly or northwesterly direction.

We hope you enjoyed this article.  Our goal was to make Monsoon Season easier to understand.

Interesting Saguaro Cactus Facts

One of Arizona’s most majestic, lovable desert cactus plants is the Saguaro, Carnegiea gigantea. Being aware of the saguaro’s history and incredible internal design, it is an honor to walk close to the Giant Saguaro that is over 150 years old and standing tall.

Sonoran Desert cactus tall
Giant Saguaro Cactus of Arizona

These desert cacti are large, tree-like columnar cacti that develop branches (or arms) as they age.

Saguaro Cactus can not tolerate freezing temperatures in the winter and this is what limits their range.

Saguaro National Park
Saguaro Cactus

Saguaro FACTS:  Saguaros are a very slow growing cactus.  A 10 year old plant might only be 2 inches tall.

How tall can a Saguaro Cactus grow?  It can grow 40 to 60 feet tall.

Saguaro cactus roots are only 4-6 inches deep and travel out as far from the plant as it is tall. There is one deep tap root that extends down into the ground.

A Saguaro Cactus can gather enough water through its remarkable root system, during a significant rain, to last a year!

Why are there holes in the Saguaro Cactus?  The gilded flicker and Gila woodpecker excavate nest cavities inside the saguaro’s pulpy flesh.

Birds nesting in the Arizona Saguaro Cactus

Cactus Wrens are common birds that live in the holes (nests) of the Saguaro Cactus.

When a saguaro reaches 35 years of age it begins to produce flowers.

A Saguaro can only be fertilized from a different cactus – cross pollination.  Only a few bloom each night awaiting to be pollinated and close by late morning.

Because the major part of a desert saguaro cactus is made up of water, an adult plant may weigh 6 tons or more. This tremendous weight is supported by a circular skeleton of inter-connected, woody ribs.

After the saguaro dies its wood ribs can be used to build roofs, fences, and parts of furniture.  The holes that birds nested in are called saguaro boots.

Native Americans used saguaro boots as water containers.

Saguaro branches normally begin to appear when the cactus reaches 50 to 70 years of age.

The average life span of a saguaro is approximately 175 years of age.  Experts have estimated that a Saguaro Cactus with more than 5 arms can be 200 years old.

nurse tree for saguaro cactus
Yellow Palo Verde Tree is a nurse tree

Young saguaro cacti can be very hard to find because they grow under the protection of a “nurse tree”.  The nurse tree releases nitrogen in the soil which the Saguaros and other desert cacti use to grow healthy and strong.

Saguaros sometimes grow in odd shapes or forms. The growing tip of the cactus occasionally produces a fan-like form which is referred to as crested or cristate.

These crested saguaro cacti, Carnegia gigantea forma cristata, are rare.  Biologists are not sure why these Saguaros grow this fan-like shape.

Arizona has strict regulations about the harvesting, collection or destruction of  The Arizona Saguaro Cactus. It is illegal to harm a Saguaro in Arizona. During building or construction, precautions must be taken to move every saguaro that may be affected.

Desert turtles in Arizona – difference between male and female tortoises

ARIZONA TORTOISE | Turtles – Do NOT pick up the Desert Tortoise unless it is in harms way. The Tortoise will get scared and release the water in its bladder and most likely die during the dry season.

It is also illegal and detrimental to the desert tortoise populations to collect tortoises from the wild.

Removing any of the six species of Arizona’s native turtle / tortoise can severely affect local populations because they reproduce very slowly in natural conditions.

  • Desert Tortoises
  • Ornate Box Turtles
  • Mud Turtles
  • Painted Turtles

What is the difference between Male and Female Tortoises?

It can take up to 20 years before the Desert Tortoise starts showing physical characteristics that are typical of the 2 sexes.  The sex of a tortoise is based on the temperature of the nest and NOT genetics.

One way to tell the difference between the female and male tortoise is by the TAIL.  A male tortoise has a larger tail than the female.   The female’s is very short.  Also, male tortoises have 2 chin glands that are enlarged during mating season.  Sometimes a white gooey liquid comes out of the male’s chin glands.

The Desert Tortoise is called – “A LIVING DINOSAUR”

Facts:

Dinosaurs became extinct but turtles & tortoises have thrived in their present form for approximately 150 million years.

This Tortoise is one of four species that have remained unchanged since the Oligocene Epoch  27-37 million years ago.

Arizona Game and Fish Department’s TURTLE PROJECT works to manage and conserve all six species of turtles/tortoises.  They receive hundreds of young and adult Tortoises that have been displaced due to construction or raised in captivity. The TURTLE PROJECT has Tortoises available for adoption.

A captive tortoise has to be raised in captivity for the rest of its life.   It can live to be 100 years old.

Gopherus agassizii

If a captured tortoise is released in the wild it can introduce diseases and jeopardize the wild populations.  URTD (an upper respiratory infection) has caused catastrophic die-offs in the Mojave tortoise population, resulting in Mojave Tortoise being placed on the federal listing under the Endangered Species Act

If you are interested in Tortoises but are not in the position to adopt, you can still participate in the Sponsor-a-Turtle program.  By donating to the Turtles Project, you will help project biologists purchase specialized gear so that they may continue to plan and implement conservation and management.  Click here to download the Sponsor-a-Turtle program brochure.

A tortoise is a high-domed turtle, with “columnar” legs,  or elephant-like.  It is more terrestrial ( an animal that lives on land as opposed to water) than the turtle is, Arizona Tortoises go to water only to drink or bathe. They are NOT designed for swimming.

When the tortoise/turtle species emerges from winter torpor(brumation),  it will eat new growth cacti and their flowers, grasses and some shrubs.

** What is Brumation – it is different than hibernation; when mammals hibernate, they actually sleep; when reptiles brumate, their metabolism slows down making them less active, and so they just barely need to eat.

Reptiles can often go through the whole winter without eating.  Brumation is triggered by lack of heat and the decrease in daylight hours.

A single tortoise may have a dozen or more burrows distributed over its home range. These burrows may be used by different tortoises at different times. Some of their burrows just extend beyond the shell of the tortoise inside.

The tortoise is able to live where ground temperatures may exceed 140 degrees F, because of its ability to dig underground burrows and escape the heat.

Desert tortoises generally emerge from their burrows mid-March to feed. During this approximate six week period: fresh green grass and spring wildflowers are their primary nutritional source.

In the Sonoran Desert of Arizona,  tortoises tend to live on steep, rocky hillside slopes in Palo Verde trees/shrubs and Saguaro Cactus areas.

The tortoise’s forelimbs are flattened with well-developed muscles for digging burrows and the hind limbs are elephantine in which the female tortoise uses to dig her nests.

Fighting may occur any time male tortoises encounter each-other. When fighting the desert tortoise/turtle will use the gular scutes to ram and flip other males. A flipped male will usually right itself after the defeat, but if it cannot, it will die.

female and male tortoise difference

The turtle shell is a highly complicated shield for the tortoise;, completely enclosing all the vital organs and in some tortoise/turtle species even the head.

The Shell of a Desert Tortoise

Helping to make the desert tortoise suited for desert-life is the ability to acquire almost all of its water from the plants that it eats. Because desert tortoises live in an arid climate where most of the rainfall occurs during the monsoon; the Tortoise is able to store water in its bladder for use during drought.

Adult tortoises have very few natural predators because of its thick, scaly skin and hard shell. In the Sonoran desert, mountain lions are their main predators.  Worse than predation, however, is the pressure the species is under from development, the construction of roads, and other human activities that degrade its habitat and cause mortality.

Courting, mating and copulation may occur any time that tortoises are above ground; however, there seems to be more of this behavior in late summer and early fall when the testosterone levels peak in male tortoises.

Females store sperm and their egg laying occurs in May, June and July.

A mature female tortoise might lay 4-8 white, hard-shelled eggs in a clutch and produce 2, sometimes 3 clutches in a season. Only a few tortoise eggs out of every hundred actually make it to adulthood.

After laying her eggs, the female tortoise leaves the nest.  The soil temperatures support growth of the embryos.  The incubation period is 90 to 120 days.

Unfortunately, slow growth and soft shells make baby tortoises particularly vulnerable to predators.

 

Arkenstone Cave in AZ – Protected living cave at Colossal Park

Arkenstone Cave was discovered near the Rincon Mountains of Southeastern Arizona in the 1960’s.  This living cave is protected by the county and accessible only to a few scientists and researchers.

Arkenstone Cave in Arizona

We have spent a great deal of time investigating information regarding Arkenstone and La Tetera Caves.  Our most important finding has been the fact that Pima County regards these living caves as treasure troves of precious, immeasurable scientific information.

Access is extremely limited; but a visit to Colossal Cave Mountain Park Museum can provide the curious with results of the past and latest research conducted inside Arkenstone Cave.

Here are some of the research highlights provided from the Museum Caving Rooms at Colossal Cave east of Tucson, AZ.

Colossal Cave Mountain Park
Arkenstone Cave is used for research

ARKENSTONE is an active KARST CAVE, which means the breaking down of limestone has produced fissures, sinkholes, caverns and underground streams.

Most caves are formed in limestone.  Simply put, it dissolves from precipitation mixing with carbon dioxide and the decaying organic material in the soil.  This dissolution process is extremely slow.  Thousands upon thousands of years!

Arkenstone, La Tetera and Colossal Caves are located in Colossal Cave Mountain Park, Arizona.  Colossal Cave is dry and considered a dead cave.  La Tetera and Arkenstone are alive and adorned with calcium carbonate formations produced through slow precipitation.

SPELEOTHEMS in Arkenstone Cave
Arkenstone Cave Crystal formations

Mineral deposits in caves are called SPELEOTHEMS.

ARKENSTONE CAVE is called:

  • a WILD cave
  • a WET cave
  • a LIVE, “active” cave

What does this mean… A wild cave has no provisions for the general public and is dangerous without expert equipment and experience.  A wet cave has precipitation.

Colossal Cave Mountain Park Caves

A live cave has life forms, insects, faunal, animal, species and unusual speleothems.

Pima County and Colossal Park employees have an overwhelming desire and responsibility to protect La Tetera and Arkenstone living Caves.

species found in Arkenstone Cave, Colossal Mountain Park, AZ

Several new species have been found in Arkenstone that are endemic to Arkenstone, meaning they only exist in Arkenstone Cave.  A few researchers have special grants to work in these living Arizona Caves.

In recent years, 7 new species of fauna have been found.  The Arkenstone Cave exhibit at Colossal Mountain Park Museum gives detailed descriptions.

Animals that live in caves are often put in the category called TROGLOBITESTroglobitic species tend to be very unusual organisms.  For example, they may have loss of pigment or no eyes.  These characteristics would be adaptations to their subterranean life.

Rarer bones in the deposit represent a smaller species of bat (Myotis) and the extinct vampire bat Desmodus stocki.

This is the first record of D. stocki in what is now the Sonoran Desert and the second location for the vampire bat species in Arizona.

Rincon Mountains Arkenstone Living Cave
Extinct Vampire Bat found in Arkenstone Cave

Due to leaching in the alkaline cave environment, the bones could not be dated by radiocarbon, but the fossils probably date to the late Pleistocene Age  —  (Late Pleistocene Bats from Arkenstone Cave, Arizona by Nicholas Czaplewski and William Peachey, December 2003)

The Late Pleistocene age was dominated by glaciation  Many larger land animals, MEGAFAUNA, became extinct over this ICE AGE.  Experts estimated that 30% of the Earth’s surface was covered by ice.  Pleistocene vampire bats most likely were capable of surviving in cooler temperatures than the modern bats of today.

The extinction of Desmodus stocki paralleled the extinction of the megafauna.

Research indicates that Arkenstone Cave was the site of a maternity colony of Myotis thysanodes.  Myotis thysandoes is a larger species of bat, mammal.  These bats begin nursing colonies, female nurse bats remain at the roost while other adults are out foraging.

Virtually all of the bones collected were of that species.  Remains of Desmodus are consistent with a single individual, and those of a small Myotis (bat) consistent with two individuals (Czaplewski and Peachey 2003).

Desmodus stocki was 20% larger than the still extant common vampire bat.   Lets put aside the scary name, VAMPIRE, and let me share some benevolent behavior of Vampire Bats that may gain your admiration for the Pleistocene bat, Desmodus Stocki.

Vampire Bats are one of the few animal species that show caring behavior for those beyond their family group.  They even adopt orphaned bats and will share their food.  Look at the photo above for more altruistic vampire ways.  🙂

Scientists state that fossil records of Desmodus stocki are uncommon because these bats mainly roosted in hollow trees and any remains would decay along with the wood.
