Golf Digest Magazine says in its 2017/2018 rankings profile:

While Tom Fazio is best known for creating massive landscapes for his designs, Spring Hill required little manipulation of earth. Fazio utilized the existing rolling topography to form what is one of his most natural designs. Holes are isolated from one another by thick forests of evergreens and, in one section of the property, acres of maple trees, which provide a brilliant color display each fall. With several tight fairways, marshland along some edges, many uphill approach shots into elevated greens and subtle movements in the putting surfaces, Spring Hill is also one of Fazio's most challenging designs.
