Rescuers Use New Tech to Save Caver Trapped Vertically in Alberta’s ‘Psych Squeeze’
The volunteer-built QDX-M radio helped rescuers communicate through rock during a 13-caver, 10-firefighter operation, Search and Rescue Alberta said.
On Saturday, a caver trapped in the "Psych Squeeze" at Rat's Nest Cave in Canmore, Alberta, was rescued using volunteer-built underground radio technology deployed for the first time.
Alberta/BC Cave Rescue developed the QDX-M radio system to overcome communication failures with traditional methods like phones or GPS, enabling signals through more than 500 metres of solid rock.
Hammer drills removed rock to extract the caver in a process measured in "inches per hour," with 13 cave rescuers, 10 firefighters, and two Kananaskis Mountain rescue members participating.
John Alexander, CEO of Search and Rescue Alberta, said the rescue "is a display of what can be achieved when multiple emergency response agencies come together in collaboration" with 1,500 volunteers.
Such units are not currently available commercially at an affordable cost, making volunteer design work essential for enabling reliable communications during future deep-cave rescue operations.
