On Sunday, Agassiz RCMP officers were investigating a complaint of shots fired about 50 kilometres in on the West Harrison Forest Service Road when they happened upon the seemingly-abandoned campsite.
Police say Vancouver resident Raymond Salmen had been using the site, but officers have been unable to find the 65-year-old.
Agassiz-Harrison Search and Rescue and an RCMP helicopter crew began a search for Salmen on Monday.
RCMP Cpl. Len vanNieuwenhuizen said Tuesday the search was ongoing.
"We are concerned for Mr. Salmen's safety," he said in a written statement.
"This is a wilderness area with no formal campsites. This area is frequented by campers and we are hoping that someone may have seen Mr. Salmen. We believe that he has been at this camp site since May 28th."
Cpl. vanNieuwenhuizen said there is no reason to believe the complaint about shots fire is connected to Salmen or his mysterious disappearance.
On Wednesday, Agassiz RCMP officially declared the investigation a missing persons case, and released a photo of Salmen's truck and camper in case the image triggers a helpful tip.
"We are hoping that this will refresh someone's memory that has been visiting Harrison Lake, and has information that would be useful for our search," vanNieuwenhuizen said.
