Gifford Pinchot National Forest in Washington and Gifford Pinchot State Park in Lewisberry, Pennsylvania, are named in his honor, as is Pinchot Hall at Penn State University. A large Coast Redwood in Muir Woods, California, is also named in his honor, as are Mount Pinchot and Pinchot Pass on the John Muir Trail in the Kings Canyon National Park in California. The Pinchot Sycamore, the largest tree in his native state of Connecticut and second-largest sycamore on the Atlantic coast, still stands in Simsbury. The house where Pinchot was born belonged to his grandfather, Captain Elisha Phelps, and is also on the National Register of Historic Places. He is also commemorated in the scientific name of a species of Caribbean lizard, Anolis pinchoti. In 1963, President John F. Kennedy accepted the family's summer retreat house, Grey Towers National Historic Site, which the Pinchot family donated to the U.S. Forest Service. It remains the only National Historic Landmark operated by that federal agency.
