WATCH: St. Paul Fire Dept. Rescues Man Stuck In Cave 100 Feet Above Ground

MINNEAPOLIS (WCCO) -- Authorities say no one was injured after a technical rescue in St. Paul early Sunday morning.

Officials say Rescue Squad 3 responded around 1:30 a.m. Sunday after receiving a report of a man stuck in a cave near Wabasha and Shepard Road.

The victim was stranded 100 feet above the ground with no way of getting down, the fire department said.

"We've got hundreds of miles of caves and tunnels underneath St. Paul and people are in an out of them pretty frequently," technical rescue coordinator for the St. Paul Fire Department Captain Mike Aspnes said.

"People often times don't understand the gravity of the situation or really the terrain that they're working on. And pretty soon they find themselves in a precarious situation and that's why we train and that's why they call us," Captain Aspnes said.

Using ropes and harnesses, the fire department's high angle rescue team rappelled down the tricky terrain.

The St. Paul Fire Department tweeted about the cave rescue.

"Because the bluff face is not particularly straight up and down, it's not very clean, they had to spend a fair amount of time protecting the edges to make sure rope wasn't cut while they performed the rescue," Aspnes said.

"There was a small piece of wire, small diameter wire that was stretched from the top of bluff to the location where he was stranded and because it was so small and hard to grab onto he wasn't able to climb back up," Aspnes said.

Firefighters say the caves pose several dangers such as low oxygen or high carbon monoxide from people lighting fires.

Aspnes said 120 fire fighters in the department are trained for high angle rescues, and that training happens monthly. Just a few reasons why he feels only professionals should enter the cave system.

"We just finished our yearly competency test so everyone was fresh on their skills and they did a great job," he said.

St. Paul police said the man rescued was the one who called 911, he will not face any charges.
