Los Pinos Ranch, founded in 1912 by Amado Chaves, has operated as a guest ranch for a century. Part of the phenomenon of wealthy and educated individuals from the East Coast seeking outdoor recreation in a rustic yet cultivated atmosphere, Los Pinos Ranch was home to and the place of respite for many historically significant people. Notable figures who occupied the ranch include Charles Lummis, Marc Simmons, Paul Horgan, and Robert J. Oppenheimer. Oppenheimer frequented the ranch over a period which spanned decades, starting when he was a teenager. His horseback rides with Amado’s daughter Kia Chaves, a lifelong friend, eventually led Oppenheimer to the site of the Manhattan Project in Los Alamos.
