Elena Cernicka, 35, left behind her husband and two young sons when she and two other climbers fell 600 metres to their deaths while climbing a challenging couloir on the remote peak.
Cernicka was a patient safety coordinator with Providence Health Care who lived on the North Shore and climbed at the Edge Climbing Centre.
Owner Henry Wang said the climbing community now wants to do something to help the family.
"Many of her friends have climbed or still climb at the gym, so she's still very much part of the family. So we would like to try to help the family out," said Wang.
Wang hopes the climbing centre will be packed from 1 p.m. PT to 11 p.m. PT.
"The entire day's proceeds will be donated to family, 100 per cent of whatever day-passes people buy."
Wang said other gyms are planning similar fundraisers. By Friday morning, more than $10,000 had already been donated to the online fundraising efforts.
The two other climbers killed in the fall were Neil Charles Mackenzie, 31, of Vancouver and Stephanie Grothe, 30, of Vancouver.
Grothe was a PhD student in physics and astronomy at the University of British Columbia and originally from Germany.
Mackenzie was a post-doctoral fellow at UBC in the Centre for Blood Research and originally from Scotland.
