“The cave you fear to enter holds the treasure you seek”*…
Photographer Ryan Deboodt and his team hiked (for days)…
… then flew a drone even further into the belly of Vietnam’s Hang Son Doong, the world’s largest known cave.
See more extraordinary photos (and larger versions of those above) on Ryan’s site.

As we go spelunking, we might send crusty birthday greetings to Adam Sedgwick; he was born on this date in 1785. One of the founders of modern geology, he proposed both the the Devonian and the Cambrian periods of the geological timescale. Sedgwick was a fierce critic of the theory of evolution when it appeared, calling it “”utterly false… from first to last it is a dish of rank materialism cleverly cooked and served up”; nonetheless, he and Charles Darwin (one of Sedgwick’s students at Cambridge) were friends until Sedgwick’s death in 1873.
