Provincial police say they're heartened by the number of responses to a recent public appeal to identify male human remains recovered in Algonquin Park in 1980.

Several photos and video of a three-dimensional clay facial reconstruction were released on social media last month and O-P-P say they've received 36 fresh tips from the public.

A hiker using the a trail near Whitney discovered the remains on April 19th, 1980, and other remains and evidence were recovered from the area in a search in 1995.

The unidentified hiker is believed to have been a Caucasian male -- aged 18 to 29 years -- who likely died between July 1st, 1971 and the spring of 1978.
