In the early 1900's, Frank Graf, a mining engineer with Golden Dawn Mining Company moved his family from Michigan to Nome, Alaska. In 1909, after the gold rush, Frank's son, Art, moved to Coeur d'Alene, Idaho. He encouraged his father to move to consider land investments in Idaho. Frank bought land in what is now the Dalton Gardens area. Within a year of buying the land the rest of the family settled in the Dalton area.

Frank Graf continued buying land. He and his mother-in-law, Elizabeth Pranger, acquired 65 acres on Potlatch Hill in 1911. Following a fire, Frank converted the barn into what is now known as the "Main House". Art and his wife, Muriel, were given about 20 acres. They built what is known today as the "Anderson House".

When Frank died in 1921, his wife, Elizabeth Graf retained the Potlatch Hill property. After Elizabeth's death in 1931, her daughter, May Louise Graf Tate, inherited the land.

In 1981 Ralph Tate, May Louise's oldest son, moved into the "Main House". May Louise divided the remaining acreage equally between Ralph and his younger brother, Harold Tate.

Harold sold the easement of land, now known as Potlatch Hill Road, formerly known as the Tate Road, to aid in the development of Armstrong Park. Additional property was absorbed by Idaho Transportation Department during the raising of the I-90 freeway from its original location now known as Coeur d'Alene Lake Drive. After these developments, approximately 40 acres of the 65 original acreage remained.

Ralph died in 2007, leaving his portion of the property to his grandchildren. In 2001, Harold Tate split his property with his daughter, Virginia Tate. Virginia's 6 acres are the location of Elk Point overlooking beautiful Lake Coeur d'Alene on Potlatch Hill.
