WATERLOO – It sure wasn’t the hole-in-one Mark Mihal had in mind.
While golfing with friends at the Annbriar Golf Course on Friday, Mihal, 43, a mortgage broker from Creve Coeur, Mo., abruptly dropped into the ground on the fairway of the 14th hole. It was the first time a person – and not a ball – has disappeared beneath the turf in the course’s 20-year history.
It also was the first time in the memory of folks who study sinkholes in Illinois that a person has fallen into one.
“I was standing in the middle of the fairway,” Mihal said. “Then, all of a sudden, before I knew it, I was underground.”
Mihal said he fell into the mud floor of an enclosure shaped like a bell, 18 feet deep and 10 feet wide. The rescue was precarious, because no one knew whether the surface hole would grow or the enclosure would collapse.
A companion called the course’s pro shop, where general manager Russ Nobbe gathered some rope and a ladder and rushed to the rescue. Mihal had dislocated his shoulder, so Ed Magaletta, a friend and a real estate agent, climbed down and put a rope around Mihal’s waist so he could be hoisted to safety.
The rescue took less than 20 minutes, but Mihal said his mind quickly went to an incident 2 weeks prior in Seffner, Fla., where a sleeping man dropped into a huge sinkhole that opened beneath his bedroom. Authorities never recovered the body of that victim, Jeffrey Bush, 36.
Nobbe, the general manager whose family owns the course, said, “You try to think what you can do to help.” He added, “You’re trying to imagine where in the world there’s a sinkhole on 14.”
Philip Moss, a geologist who has examined the void, said sinkholes are usually visible. But in this case, Mihal said he was standing still as the ground gave way beneath him.
“This guy just really was in the wrong place at the wrong time,” Moss said.
Sinkholes are common in the St. Louis region, he said, because the bedrock here is limestone. It can dissolve in rainwater, which makes an opening he calls a “conduit.” Those large enough to accommodate people are called caves. New openings usually reveal themselves during or right after heavy rain.
“It’s a gradual process that creates a void in the soil,” Moss explained. “Over time, [the void] migrates upward through the soil to where the soil arch gets too thin to support the weight of what’s over it, and it collapses.”
