Before my family moved to Virginia, most of my childhood was spent in western New York. I vaguely recall seeing Mark Twain's study while riding through Elmira with my father, but I don't remember ever stopping to take a closer look. Thus, you might say that this stop on my road trip was long overdue. The first photo is from the south, and looking uphill.
The entrance is from the west. Through the open doorway, you can see the fireplace that forms the eastern face of the study.
On nearby College Avenue is this sign.
As seen in this shot from the southwest, the study is surrounded by trees and a light pole.
A short walk from the study brings you to a statue of Mark Twain, and one of Olivia. As for the function of the conical sheath around the nearby tree, I have no idea.
The sidewalks of the Elmira College campus have been interspersed with bits of wisdom from Samuel Clemens, such as this one near where I parked, which these days seems more relevant than ever.
More on Mark Twain's study may be found at Atlas Obscura, The Constant Rambler and Mark Twain Country.
