These
are pictures of John Preston from Rochester Minnesota. John
did a
thirty minute hike back through a cave system to dive a virgin sump through
mud and rock in his DUI drysuit. When we climbed out of the 80 ft hole
on
the surface the temp was -3 degrees and John's drysuit got kinda stiff as
you can see in the last picture.
