The 32-year-old man was pulled from the caldera about 9:40 p.m.
On Thursday, he’d been upgraded to stable condition.
Army officials said he is a Schofield Barracks soldier who was on the Big Island as part of a unit on a training mission at Pohakuloa.
Ben Hayes, acting park spokesman and chief of interpretation, said another visitor saw the man fall from the 300-foot cliff about 6:30 p.m. and immediately alerted authorities.
Hayes said the man fell after climbing over a permanent metal railing at the Steaming Bluff overlook to get a better vantage point. That’s when the ground underneath him apparently gave way.
Remarkably, rather than plummeting to the caldera’s floor, the man fell about 70 feet and landed on a narrow ledge.
