Maunds Spring
Location: Jackson County, Florida, United States
Maunds Spring is located less than one mile from the Hinson Preserve primitive boat launch along the Chipola River.
The spring sits in a scenic basin at the end of a short spring run that empties directly into the river. The entrance to the cave lies at the bottom of the basin in a vertical fissure crack.
Maunds is known for its frequent fissure cracks along the main passage, distinctive organic-coated passage known as Insulation Corridor, and moderate overall length of approximately 3,500 feet of surveyed passage.

Geological Context
The spring emerges from Florida’s karst limestone and discharges into a small, picturesque basin before flowing into the Chipola River.
The cave entrance is a vertical fissure approximately 40 feet deep from the surface. Tree debris frequently accumulates at the opening, often partially choking access. While the debris can make the entrance appear restrictive, the opening itself is large enough to accommodate backmounted cylinders when clear.
The system contains both vertical relief and low-profile restrictions characteristic of fissure-based development.
Structure & Layout
The cave entrance begins as a fissure crack in the basin floor, descending to approximately 40 feet before opening into a chamber.
The first chamber slopes sharply downward to around 60 feet where a low sidemount restriction is encountered. Although the restriction requires contact with the cave, the smooth limestone floor typically prevents significant visibility disturbance.
Shortly after passing through the restriction, divers encounter a wine bottle placed within the passage – a recognizable interior landmark.
Beyond this point, the cave splits:
The left passage leads to a distinct area known as Insulation Corridor.
The primary passage continues to the right, extending approximately 2,200 feet from the entrance before terminating at a very low and tight restriction.
Hydrological Characteristics
Maunds Spring exhibits stable discharge typical of Chipola River spring systems.
River stage can influence entry conditions and current strength, though interior flow remains moderate relative to higher-discharge springs in the region.
Sediment sensitivity varies by section, particularly in lower or more confined areas.
Insulation Corridor
Insulation Corridor is characterized by an unusual organic material coating portions of the floor, walls, and ceiling.
The material resembles blown attic insulation and can accumulate to depths approaching one foot in certain sections.
This corridor presents a visually distinct environment compared to the rest of the cave system and requires careful propulsion to avoid disturbing accumulated material.
Exploration & Survey History
In the mid-2010s, survey efforts extended the end of the line by approximately 250 feet, identifying previously undocumented passage.
A comprehensive survey and updated map were completed during this period, bringing the total documented length of Maunds Spring to approximately 3,500 feet.
These efforts improved understanding of the cave’s branching structure and overall layout.
Portions of this cave system were explored and surveyed during cave dives conducted by Rob Neto while documenting Florida’s underwater cave systems for the book The Hidden Rivers of Florida.
Cave Data
Location: Jackson County, Florida
Water Source: Floridan Aquifer
Cave Type: Submerged limestone cave system
Depth Range: 15–80 feet (4.5–37 meters)
Water Temperature: ~68°F (20°C)
Geology: Karst limestone
Primary Access: Spring vent
Exploration Status: Fully explored
Current Status
Maunds remains an active spring system characterized by:
- Vertical fissure entrance
- Periodic tree debris obstruction
- Sidemount-restricted sections
- Distinct organic-lined passage
- Moderate overall length
The system’s layout combines manageable penetration distances with technical considerations at both the entrance and interior restrictions.
