EDMONTON — It was 21 years ago that Laurel Holland’s father disappeared off the face of an Alberta mountain, but now she is hoping to find peace by writing a memoir about her father.

“I was five when my father went away,” says the New York-based actress. “It’s the kind of thing you don’t forget — being told someone you love won’t be coming back, that he’s gone and can’t be found.”

On April 3, 1989, her father, William, set out from Portland with a group of climbers to conquer Slipstream, a frozen waterfall on Mt. Snow Dome in Jasper National Park. He was on his descent when a cornice beneath him gave way and he disappeared over the edge.

Holland’s body wasn’t found until August 15, 2010, when two hikers came across it at the base of Snow Dome.

Holland felt the need to share her father’s story in her own words in a book to be called Spindrift.

“Somewhere along the way, because there was no body, I convinced myself my father was still alive,” she says.

Her book will chronicle her father’s life as an adventurer and climber and how his risks ended up affecting his family.
