When people think of Florida, they may think of Disneyworld, sandy beaches, oranges, or sunshine. Then again, if you possess a less-optimistic outlook, you may conjure up images of giant bugs, hurricanes, or sunburns. In recent years, another scary natural phenomenon common in Florida captured people’s attention: sinkholes.
The Florida landscape features a large number of sinkholes. According to the Florida Department of Environmental Protection, there are around 27,000 reported sinkholes or sinkhole-affected areas within the state. While most of these sinkholes garner little attention, others sometimes turn into national news. This tends to happen when a sinkhole rapidly appears and swallows up roads or peoples’ homes.
In particular, one Florida sinkhole attracts attention due to its dangerous residents. Known as “Deep Hole,” this alligator-infested sinkhole boasts a population of over 100 gators. Despite its deadly residents, the surrounding area contains several popular fishing, hiking, and camping spots. Keep reading to learn more about Deep Hole, the alligator-infested sinkhole in Florida.
Deep Hole: The Alligator-Infested Sinkhole
Deep Hole is located within the 58-square-mile Myakka River State Park outside Sarasota, Florida. Myakka River State Park ranks as one of Florida’s largest and oldest parks. You can find Deep Hole on the northwest bank of the Myakka River near the southern end of Lower Myakka Lake. The Myakka River feeds into the lake and flows through Myakka River State Park, which shares its name with the river.
According to best estimates, Deep Hole measures about 134 feet deep at its deepest point. At its widest point, Deep Hole measures around 200 feet wide. Murky water fills the Deep Hole year-round, which makes it difficult to study. Studies are further hampered by the sinkhole’s large population of American alligators. Water levels in the sinkhole vary depending on the time of year. During the wet season, water levels can rise nearly 6 feet. Similarly, in dry years the water levels can fall substantially.
Deep Hole is a static sinkhole, unlike some other sinkholes, meaning it is not fed by an underground mineral spring. Water temperatures can vary drastically near the surface and deeper within the hole. The lack of moving water, low oxygen, and high levels of hydrogen sulfide make living at the bottom of the sinkhole almost impossible. Almost no plant life lives along the bottom of the sinkhole, which is littered with fish carcasses. These fish likely die during the dry season due to a lack of oxygen or food in the sinkhole.
Where is Florida’s Alligator-Infested Sinkhole – Deep Hole Located on a Map?
Deep Hole is located within the 58-square-mile Myakka River State Park outside Sarasota, Florida. You can find Deep Hole on the northwest bank of the Myakka River near the southern end of Lower Myakka Lake. The city of Sarasota is in the central part of the state – on the western Gulf Coast side. The city borders Sarasota Bay with the beach accessed by a bridge that takes Hwy 278 to Lido Key.
What are Sinkholes, and How Are They Made?
A sinkhole is a depression in the ground created after the surface layer of the ground collapses.
The majority of sinkholes form as a result of karst processes. These processes involve the dissolution of carbonate rocks by chemicals or the collapse of underground caves. While some sinkholes form slowly over time, others can form rapidly. The natural process of erosion slowly creates the optimal scenario for a sinkhole to occur. From there, the surrounding landscape determines how and when the sinkhole develops.
The Ecology of Deep Hole
You can find a diverse array of plant and animal life around Deep Hole. The Myakka River State Park features around 37.000 acres of wetlands, prairie, and woodlands. Common plants in the park include longleaf pine, saw palmetto, and bald cypress.
According to park records, close to 40 species of fish reside within the waters of the Myakka River and its lakes. Additionally, the park is home to around 48 reptile species, 22 amphibian species, 32 mammal species, and 255 bird species. Of these animals, the American alligator ranks as the park’s — and Deep Hole’s — most notorious species.
The number of alligators around Deep Hole varies depending on the time of year. During the dry season, animals in the park tend to congregate around water sources. At that time, you can find as many as 150 gators in the water and the land around Deep Hole. No one knows exactly why so many gators live in such a small space. Most likely, the alligators in Deep Hole gather for protection, warmth, and a greater chance of finding food. This holds especially true during the dry season when the diversity around the sinkhole increases.
American Alligators Description
The alligators found in Deep Hole are all American alligators (Alligator mississippiensis). Also known as common alligators or simply gators, American alligators belong to the family Alligatoridae in the order Crocdilla. Along with the Chinese alligator, they represent the two remaining extant alligator species on Earth. That said, American alligators measure larger than their Chinese cousins. On average, adult males measure 11.2 to 15.1 feet long and weigh up to 999 pounds. Females measure slightly smaller, with most running between 8.5 and 9.8 feet long.
American alligators are native to the southeastern United States. You can distinguish them from the American crocodile by their wider snout, distinctive overlapping jaws, and darker scales. Additionally, unlike American crocodiles, which often live in saltwater, American alligators almost exclusively live in freshwater. On the other hand, American alligators tolerate cooler waters much better than American crocodiles.
American alligators represent the peak of reptilian evolution. These apex predators eat whatever they can catch, including birds, fish, amphibians, mammals, and reptiles. They will even eat other gators if given the chance. American alligators serve an important role in maintaining the health of the environment and are often viewed as a keystone species. Their gator holes — like Deep Hole — act as gathering spots for a diverse array of wildlife. Moreover, when they build their nests along the banks of their water holes, they dig up the soil. This creates dry spots for other animals to feed and make their nests.
Today, the IUCN lists the American alligator as a species of Least Concern. However, the species faced significant threats during the 20th century. Overhunting and habitat loss drove the American alligator to the brink of extinction. Luckily, legal protections and the efforts of activist groups managed to recover American alligator populations.
Visiting Deep Hole
To reach Deep Hole, you must walk two miles down a dirt road located off State Road 72. Given that the sinkhole technically resides within a wilderness preserve, you cannot easily access Deep Hole. No signs mark the route to the sinkhole, and no major tour groups travel the route. In fact, Myakka River State Park authorities only allow 30 people to visit the sinkhole every day. That said, visitors consider the trip well worth it if you enjoy animal watching.
Still, you must be careful when visiting Deep Hole. While rare, alligators can and will attack humans. Most attacks happen when people accidentally disturb alligators by falling into the water near them. With a bite force of 2,980 psi, an American alligator can cause a person serious harm. That said, on average, American alligators kill just one person each year in the United States.
Myakka River State Park is open 365 days a year from 8:00 AM until sunset. The park charges visitors $6 per vehicle. Today, the park contains a visitor center, two picnic pavilions, and five log cabins available for rent. Popular activities in the park include hiking, camping, fishing, and animal watching.
