Cpl. Tiffany McGregor says three men from High River and Okotoks had been hiking in the area since early Saturday.
Late in the day, one of them had trouble with his knees and could no longer walk.
Another man in the group walked two kilometres to a road where he was able to get cell service and call for help.
McGregor says police and conservation officers used snowmobiles to get the remaining pair out of the bush about 1 a.m. Sunday.
She says temperatures had dipped to about -35 C, but the men were wearing proper clothing and were cold but not hypothermic.
