The Chase Ranch "team" is a cooperative partnership between the Chase Ranch Foundation and the Philmont Scout Ranch, the premier national high-adventure camp of the Boy Scouts of America.
The Chase Ranch was founded in 1869 by Manley and Teresa Chase who purchased about 1000 acres from the Maxwell Land Grant. The ranch was operated by the Chase family until the death of Manley and Teresa's great-granddaughter Gretchen Sammis, a 1986 inductee into the Cowgirl Hall of Fame and Western Heritage Center.
Prior to her passing in 2012 at age 86, Gretchen Sammis established the Chase Ranch Foundation whose mission and purpose is to preserve the legacy of the Chase Ranch and to educate the public about cattle ranching and the heritage of the American western cowboy lifestyle.
