Built by a caver,
for cavers

CaveFinder was built by Zach Englebert — a caver, National Speleological Society (NSS) Director, and former cave inventory technician who spent years ridgewalking before wondering if terrain data could make every trip more productive

In 2019, Zach served with the Montana Conservation Corps to search for caves in the Pryor Mountains of Montana and Wyoming for the US Forest Service and Bureau of Land Management. The crew documented over 150 karst features that summer, and the work was published in NSS News. But the process was the same one cavers have used for decades: pick a ridge, walk it, hope for the best

After that summer — and years of professional karst survey work in New Mexico using drones, ground-penetrating radar, and GIS — the question became obvious: high-resolution LiDAR data exists for most of the country at 1-meter resolution. It sees every dip, depression, and terrain feature invisible from the surface. Why wasn't anyone using it to find caves systematically?

CaveFinder is the answer to that question. It automates the terrain reading that experienced cavers do intuitively, but does it across an entire landscape in minutes

Traditional cave hunting means driving to an area, picking a ridge, walking it, and hoping. Hours of bushwhacking through poison ivy to find a tree fall. Or nothing. Meanwhile, high-resolution terrain data sits unused because there's no easy way to analyze it

The USGS has been systematically collecting LiDAR data across the country for years, creating incredibly detailed elevation maps that can reveal features invisible to the naked eye. But accessing, processing, and interpreting that data requires GIS expertise and significant computing resources that most cavers don't have

CaveFinder automates what experienced cavers do intuitively — reading terrain for signs of subsurface voids — but does it systematically across an entire landscape in minutes

The system was extensively validated against known terrain features across multiple states. Draw a box on the map, and the system downloads elevation data, runs the analysis, and returns ranked candidates with confidence scores, depth estimates, and terrain visualizations

Not every candidate is a cave — and we're upfront about that. But by narrowing thousands of acres down to a handful of high-confidence targets, you can make every field trip count

CaveFinder is a product of Buzzy LLC, based in Albuquerque, New Mexico. It wasn't built by a startup team that Googled "what is a cave." It was built by someone who has mapped caves in southeastern New Mexico, fabricated bat-protective gates for endangered species in NM, AL, WV, and NY, and walked more ridges than he can count

Every feature was designed around real field workflows — from the Ridgewalk Planner that generates printable route PDFs, to the Mark as Checked system for tracking verification progress across trips. If it's in the tool, it's because it was needed in the field
