In film footage released Monday, video shows a diver swimming along towering limestone walls while hauling an expanse of equipment and safety gear.
A flashlight illuminates some of the deepest depths recorded at the Roaring River cave in Cassville, where past dive teams were limited to traditional scuba equipment and only descended a little more than 200 feet, according to the Department of Natural Resources.
Those records were shattered this year, and there's still more cave to explore.
The KISS Rebreathers dive team — the acronym stands for Keep It Super Simple — made it to 344 feet during their dive in September, Lead Exploratory Diver Mike Young said in the video clip.
