Trevor Norman, 49, and his daughter Zarah, 10, had set out on an overnight backcountry ski trip on Saturday.
Police launched a search after they failed to return as scheduled on Sunday afternoon. The pair were located in an area known as the Windlip around 11:30 a.m. on Monday.
"The tent was located at the base of a rock face," said RCMP Sgt. Rob Knapton.
"From our investigation, it appears that a large boulder fell from the rock face at some point, landing on the tent with both occupants inside and killing them both," he added.
Knapton said there was lot of wind and precipitation on the weekend, and the avalanche risk was fairly high.
Police said father and daughter, who were from North Vancouver, had made the same trip before.
Victoria Miles, spokeswoman for the North Vancouver School District, confirmed that Zarah Norman was an elementary student there.
"Today counsellors with our district critical incident team were on site and available to support students and staff at the school in dealing with the beginnings of their grief," Miles said.
