Piney Ridge was a short-lived private sanatorium on Big Whitefish Lake in Crow Wing County. Dr. J. H. Sandberg moved to northern Minnesota from Red Wing, and he built a summer cottage on the lake in 1900. In 1901, he built 12 one-room log cabins and set up 13 floored tents. This was intended to be a summer fishing resort catering to physicians, but he soon advertised it as a tuberculosis sanatorium for incipient cases. Rates were $10 to $15 a week. When the Minnesota legislature was seeking sites for a state sanatorium, Sandberg wrote to the Board of Health to suggest Big Whitefish Lake as a suitable location. In 1906, the office building was destroyed by fire. By 1911, Piney Ridge was again advertised as a fishing resort.
Dr. Sandberg was interested in botanical studies and the James Ford Bell Museum at the University of Minnesota has many plant specimens collected by him.
