Alison Leanne Raspa, 25, was last seen leaving the Three Below Bar in Whistler around 11:30 p.m. on Wednesday.
RCMP say her cellphone was found at Alpha Lake park on Lake Placid Road at 6:30 the following morning. After that, investigators did a "thorough" search of the park and Alpha Lake, according to a statement but found nothing.
An RCMP dive team search of the lake didn't turn up any evidence either. A statement said police have also looked in underground parking lots, creeks, parks and any other places where Raspa could "reasonably" be.
On Wednesday night, Staff Sgt. Annie Linteau said RCMP were looking for any tips about her whereabouts.
