    South Valley's mild weather would have made the area an attractive winter camp, especially with the southwest-facing rock shelters providing warmth from the sun and protection from snows and north winds.

    In 1974, the insulation and roofing company Johns-Manville built a large headquarters at the southwest end of the valley and formed the Ken-Caryl Ranch Corporation to develop the area. In the 1980s, Johns-Manville sold its property to Martin Marietta (now Lockheed Martin), which later allowed Jefferson County Open Space to buy South Valley Park to save it from development.
