One of the most iconic locations within the Irvine Ranch Natural Landmarks, Limestone Canyon never ceases to amaze. Located between the rugged Santa Ana Mountains and central Orange County, Limestone Canyon is home to a variety of plants, animals, and unique geological features. Its oak filled valleys and year-round springs made it a popular place for Native Americans and early European settlers to hunt and forage for supplies. Later, it became an important grazing area for ranchers in the region. Today, Limestone Canyon remains one of the most pristine wilderness areas in the county and houses a number of habitat restoration projects to further ensure it biological viability. Over 20 miles of trails crisscross Limestone Canyon, providing hiking, riding, and equestrian opportunities for all levels and interests. You can sign up to participate in a number of activities in Limestone Canyon on LetsGoOutside.org, including Wilderness Access Days. Be sure to check out all this area has to offer on your next adventure, including:
The natural land in Orange County has been home to humans for thousands of years. You might have wondered from time to time how people survived – what they ate, where they sheltered, how they dealt with heat and drought. Indigenous groups like the Tongva lived in the area for many years before Spanish explorers colonized the area. These groups moved with the seasons and subsisted on the lands, using tried-and-tested techniques to prepare food you might not have known was edible.
Hesperoyucca whipplei, or Chaparral yucca, is an unmissable sight on the Irvine Ranch Natural Landmarks. When flowering, it looks something like a giant Dr. Seuss character, with shaggy cascades of white, yellow-green or purple hair springing more than mid-way up its stalk. You might know Chaparral yucca by any of its common names, such as Spanish bayonet, Quixote yucca, or Our Lord’s candle. Yucca plants typically live a few years before they flower and die, but the flowering growth can happen in a short time span: the flower part of the plant can grow as tall as 15 feet in a matter of weeks.
Tarantulas are everywhere! These large arachnids can be spotted on trails all over the Irvine Ranch Natural Landmarks in the late summer and early autumn months. Tarantulas are not aggressive animals and they will happily let you admire them from a distance, so long as they can go about their business. Tarantulas are part of the large and diverse spider family, and thus have eight legs, but they are much larger and thicker than most other spiders that live in the United States. Tarantulas ambush their prey on the ground and are known to eat small vertebrates like lizards and mice as well as large insects and other spiders.
