The Charros Foundation has matched all donations raised since Jones' death on Mount Seymour in January.
A notice posted on the North Shore Rescue website says Ian and Rosemary Mottershead have presented a cheque worth $118,000, bringing the Tim Jones Legacy Fund to just over $236,000.
To ensure the fund is sustainable, the group says only investment earnings will be used for operations and capital expenses, while the principal will be left alone.
The group says sustainable search-and-rescue funding was always Jones' dream.
This is not the first significant donation to NSR from the Charros Foundation. It also gave $250,000 to help members complete their rescue base in North Vancouver and augment the radio repeater system.
