A speleologist studies caves and cave systems, examining their geology, hydrology, biology, and archaeological significance. Speleologists earn salaries comparable to geoscientists, with a median of $99,240 annually as of 2024. While speleology isn't typically a standalone career, it's a valued specialization within geoscience requiring a bachelor's degree in geology or geography, with coursework in biology, cartography, and GIS. Employment follows broader geoscience trends with 3% projected growth through 2034.
Speleology-the scientific study of caves-sits at the intersection of geology, biology, hydrology, and archaeology. If you've ever wondered how stalactites form, why particular species thrive in total darkness, or what prehistoric cave paintings reveal about human history, speleology might be your calling. It's a niche field, admittedly, but one that offers unique opportunities to explore Earth's hidden landscapes while contributing to fields ranging from climate science to mineral prospecting.
As a prospective student or career changer exploring environmental science pathways, you should understand speleology as a specialization within the broader environmental science and geoscience fields rather than a distinct occupation. The interdisciplinary nature of cave studies means your skills transfer seamlessly across multiple scientific domains.
What Does a Speleologist Do?
Speleology is both a niche area of geoscience and a broad field of study examining many aspects of caves. There's much we can learn from these curious geological formations. Speleologists investigate how caves formed, which zoological species inhabit them, their geological profile, including how stalagmites and stalactites develop, and their internal hydrology-the profile and processes of water bodies within caves.
They're also interested in caves as habitats for paleontological and anthropological remains. Understanding human use of caves throughout history sheds light on migration patterns, ancient civilizations, and adaptation strategies.
Caves often serve as microcosms of niche ecology. Those with professional interests in biological sciences-zoology, botany, mycology, entomology-might be drawn to speleology when examining native plants and animal species that grow and thrive within cave systems. In recent years, researchers have discovered plants that can photosynthesize in extremely low light levels. Understanding these adaptations may illuminate broader questions about plant genetics and evolutionary biology.
Caves are also important sources of mineral deposits. Speleologists might prospect for these resources or examine their formation processes. They might also work as cartographers, developing maps of caves for recreational or tourism use-devising the safest routes through cave systems or implementing safety protocols. They work primarily in caves but split their time between offices, laboratories, and the cave systems they study.
What Are the Education Requirements to Become a Speleologist?
Speleology requires developing a broad set of scientific skills. High school students should ensure they earn strong grades in the hard sciences-physics, chemistry, and biology-and in mathematics. Geography is also vital for further study. Your degree choices are varied, and pursuing speleology means carefully selecting your major, minors, and electives to build complementary expertise.
Undergraduate Education (Bachelor's Degree)
The most obvious choices for your major include geology and geography. Your minors and electives should be carefully chosen to complement your major. Prioritize any cartography or survey minor, and pursue GIS training where available. Coursework in biological sciences, anthropology, and zoology would also prove valuable.
In most cases, a bachelor's degree will be adequate for your intended career as a speleologist. It's a niche area with limited direct competition, and choosing the right significant plus strategic minors should be sufficient for entry-level positions.
Graduate Education (Master's or PhD)
However, if you want to develop specific interests in certain aspects of cave studies, explore these options through a relevant master's degree. Environmental biology or chemistry, ecology, and postgraduate degrees focused on natural resources are all sound choices.
Doctoral study may be helpful for those wishing to teach specific aspects of speleology at colleges and universities or to lead major research programs. It's unlikely you'll need a PhD unless you intend to enter academia or pursue advanced research positions.

Where Does a Speleologist Work?
As this is a niche specialization, BLS doesn't hold employment data on speleology specifically. However, speleology is a subfield of geoscience, which means anyone with a professional interest in this area has transferable skills and a broad knowledge base applicable elsewhere. According to the BLS 2024 data, geoscientists work across diverse sectors.
The largest employer of geoscientists is the architectural, engineering, and related services sector, accounting for approximately 24% of positions. Speleologists working here might design or assess cave systems-for example, as tourist attractions, or evaluate and repair damaged natural or artificial cave structures.
Federal government employment accounts for roughly 18% of geoscientist positions. Speleologists working for government agencies such as NOAA, the EPA, the National Park Service, or the U.S. Geological Survey research climate change indicators, ecological assessments, and cave system management and conservation.
Management, scientific, and technical consulting services employ about 15% of geoscientists. In these roles, speleologists might provide expertise on karst terrain assessments, environmental impact studies, or resource prospecting.
Oil and gas extraction employs approximately 13% of geoscientists. Similarly, they may work on locating caves, examining them as potential geological indicators, or assessing subsurface structures.
State government agencies employ about 7% of geoscientists, in roles similar to federal positions but focused on state-specific geological surveys, environmental protection, and natural resource management.
Educational institutions also employ geoscientists as college lecturers, academic researchers, and program directors.
What Is the Job Demand for Speleologists?
Job demand for all geoscientists is expected to grow 3% between 2024 and 2034, which is about as fast as the average for all occupations. This translates to approximately 800 new positions nationally over the decade. Most opportunities will likely appear in government roles for environmental protection, continued demand for mineral prospecting and fossil fuel surveys, and the education sector.
