Krupp renamed the property Spring Mountain Ranch, and it was her principal residence until 1967. Spring Mountain Ranch State Park is located 15 miles west of Las Vegas, via Charleston Blvd. At 3,800 feet, the ranch is usually 10-15 degrees cooler than the Las Vegas Valley. Temperatures range from below freezing to above 100 degrees, and winds gusting down Sandstone Canyon are not uncommon. The summer season usuallly brings a few thunderstorms and flash floods.
Winters are cold, with occasional snow showers.
Plants typical of the desert as well as woodland can be seen, and with adequate rainfall the spring brings a burst of wildflowers. Common species sighted are desert marigold, globe mallow, brittlebush, Joshua Tree, Mohave Yucca, and indigo bush. Animal life is diverse but nocturnal, so many species go unseen. Typical desert animals include a variety of lizards and snakes, antelope ground squirrels, jackrabbits, cotton tails, kit fox, and coyote. Higher elevation species include rock squirrel, badger, mule deer, and bighorn sheep.
