Tweet Kimball adored the land at Cherokee Ranch. She proved this by amassing a vast amount of neighboring property until she owned a total of 4,500 acres.

Eventually Tweet entrusted 1,000 acres of her beloved "Summer Pasture" to residential development and the remaining 3,500 acres to the Cherokee Ranch and Castle Foundation. The Foundation placed a conservation easement on the undeveloped land in 1996, guaranteeing that it will remain undeveloped.

Tweet served as an example in conservation and many of her neighbors also dedicated themselves to keeping the land open and untouched so that today the wild inhabitants of the area and those that gaze upon them are able to enjoy more than 16,000 acres of wide open spaces. A reverence for the land is a very evident part of The Keep. As a homeowner you can be forever assured of that. A portion of every sale, of every piece of property, goes toward the Foundation to assure its operation into perpetuity.

Hundreds of elk reside here, along with mule deer, white tail deer, mountain lions, bobcats, black bears, coyotes, fox, raccoons, wild turkey, and almost 60 species of birds. Two hundred birdhouses dot the land as part of an ongoing bluebird nesting project, serving to promote the bluebird population. Volunteers monitor the boxes weekly to research nesting patterns.
