Highest, oldest and solo: scuba diver aims to break record

David Moore trains in Douglas County to break scuba diving records for age, elevation and solo attempt at Pacific Tarn lake, the largest lake in the United States.

Scuba diver David Moore has an adventurous spirit and has been training to put a high-altitude scuba diving record on the books this summer.  After turning 57 in July, Moore aims to be the oldest diver to conquer Pacific Tarn, the lake with the highest elevation in the United States, and the first to dive the lake without relying on anyone for dive support.

“I’ve been scuba diving for 30 years,” Moore said, “including volunteering as an underwater search and rescue specialist for three agencies.”

Moore’s passion for breaking scuba diving records began in the early 1990s when he and a friend successfully broke the high-altitude scuba diving record for the continental United States by exploring the depths of Lake Tulainyo, a diving location in California’s Sierra Nevada mountains.  Their achievement made waves in the scuba diving community, showcasing their determination and love for the sport.

With a desire to keep pushing the limits, Moore has set his sights on Pacific Tarn, a picturesque lake nestled in the Colorado Rockies just west of Breckenridge.  At an elevation of 13,420 feet, Pacific Tarn poses an exhilarating challenge for any diver, let alone someone aiming to break the record for oldest person to dive the lake or to solo the attempt.

Preparations for the dive have been in full swing.  When asked what he does to prepare, Moore answered, “Lots of cardio!”  He is leaving no stone unturned in his training regimen.  “I have been training since last year, usually going to the gym five to six days per week to prepare.”  He has been meticulously honing his skills, both physically and mentally, to ensure he is in peak condition for the endeavor.  He frequently hikes the incline in Castle Rock with a full pack of gear.

Moore was raised an Army brat living in many locations but spent most his years in Monterey, California.  He began diving in 1984 and achieved divemaster certification 15 years ago.

Most of Moore’s training was in underwater search and rescue but he also volunteered as a diver for the feeding show at the Monterey Bay Aquarium.

When Moore is not in the water or at the gym, he has time to write.  He recently published his first children’s book, The Legend of Charcoal and has his first reading at the Douglas County Libraries – Highlands Ranch on August 19.  He is also a professional photographer.

Married for 25 years to Nancy Neville, the couple share an online business,, that sells clothes, hats and jewelry.  They have a dog named Monterey.

The scuba diving community eagerly awaits the record-breaking attempt scheduled for August 26th.  Enthusiasts and supporters cannot help but be inspired by Moore’s spirit and determination to achieve the next level.
