But they don't show the footage☹️ "Expert captures stunning footage after leaving camera in US cave for 10 years:

"The works of the LORD are great, sought out of all them that have pleasure therein." — Psalm 111:2


I asked chat GPT how these wildlife cameras work : 
"Great questions — and the answers make this even more impressive.

Short version:

👉 No — this camera was not remote-access.
👉 Yes — he physically had to go retrieve the footage.
👉 And no — the battery did not run continuously for 10 years without attention.

Here's what actually happens with long-term wilderness cameras:

These are not Wi-Fi, cellular, or streaming cameras. They are passive trail cameras designed for extreme environments.

They work like this:

• Motion sensor triggers recording
• Camera sleeps 99.9% of the time
• No radio transmitters running
• No screens
• No Wi-Fi / cellular chips
• Only wakes for seconds per event

That makes power consumption extremely low.

How power lasts so long

Trail cameras use:

• Lithium AA or D-cell batteries
• Cold-resistant chemistry
• Ultra-low-power sleep circuits

A properly set camera can last 1–2+ years on one battery set if it's in a low-traffic area.

But not ten years straight.

What filmmakers like Anderson do:

• They revisit the camera periodically (often once a year or less)
• Swap batteries
• Swap memory cards
• Re-hide the unit
• Leave it alone again

Because Yellowstone backcountry is so remote, those visits are infrequent — sometimes once every 1–2 years.

So the "10 years" means:

👉 Ten years of accumulated footage
👉 Across multiple service visits
👉 Not one untouched battery pack running for a decade

Which actually makes the project more impressive — it means quiet long-term stewardship, not a forgotten gadget.

That's how you get a decade of pristine, non-intrusive wilderness observation.
