The seven-year-old was remembered for her determination to live life to the fullest — a smiling little girl whose favourite things — a soccer ball, sparkling sneakers, an angel ornament, were on display.
"It was quintessential in so many ways," said family friend Michelle Osry. "She was both grit and grace. She was feisty and stubborn and insistent that we live the moments, and we live them to the fullest."
"Above all, what comes through is her tenacity and her courage and her ability to stay the course."
Erin was struck and killed by a rockslide just before Christmas while out with a hiking group on Unnecessary Mountain, located north of Vancouver on the Sea to Sky Highway.
Moore had stopped to take photographs near Lonetree Creek when rocks came crashing down the creek bed, burying her.
Erin's father put together a video for the memorial so family and friends in the U.K. and South Africa could also commemorate her life.
"The love has been quite overwhelming and I think it has lifted and filled the family for the tough journey," said Osry of the memorial.
Many of Erin's friends and family wore bright colours — a tribute to the little girl who hated the colour black.
Her father described her as a bubble of joy. Her mother said she taught those around her to live in the here and now.
Messages and mementos, brought from Lions Bay to West Vancouver were covered in sparkles in tribute to Erin.
"From the moment I drove up, it was extremely moving," said Natalie Michael, Erin's Brownie leader, "but what really got me is this family just moved here when Erin was born, so it not only says what a special person Erin is, but what a special group her family is."
