DALLAS - From the photos posted on Chris Rittenmeyer's Facebook page, it's clear he was a man who loved to travel, loved adventure, and loved his wife.

Rittenmeyer, of Plano, died with a friend over the weekend at one of the most dangerous dive sites in the world, the caves beneath Eagles Nest sinkhole in Florida.

Deputies recovered the bodies of Rittenmeyer and his friend Patrick Peacock in about 260 feet of water above an area known as "the pit."

At Eagles Nest, divers are greeted with a sign that includes a picture of the grim reaper, and a warning to turn back. It's known as the Mt. Everest of dive sites.

Rittenmeyer was an experienced diver who was always well-prepared and never would have knowingly taken unnecessary risks, said his father.

"As his father I always said to him, 'Are you sure you've thought of everything, are you being careful.?'And he always said, 'Oh yeah dad, I'm way ahead of it. We've got it figured out. We're not going to take any real risks, we've got it,'" said Ron Rittenmeyer. "He called me Friday and had dived that cave and felt good about it and they were going to re-dive it again on Saturday and something happened and they didn't come out."

Nearly a dozen people have died exploring Eagles Nest.

It's been closed before, between 1999 and 2003.

According to Rittenmeyer's obituary, "funeral arrangements are being handled by Sparkman Hillcrest with a viewing for family and friends from 6pm to 8pm Thursday and a service at The Church of the Incarnation on McKinney Avenue in Dallas at 10am on Friday. Interment will be at Sparkman Hillcrest at a private family service."
