Alwut means crow. Hunwut means black bear. These words mark paths through Aliso and Wood Canyons Wilderness Park, a rugged island of coastal canyons, grassland, and riparian woodland surrounded by five suburban cities in Orange County's San Joaquin Hills. The canyon rim rises abruptly from the valley floor, and from Temple Hill on a clear day, most of Orange County spreads below. The Acjachemen and Tongva peoples once used Aliso Creek as the boundary between their territories. Their village of Niguili stood near where Aliso Creek meets Sulphur Creek. Now the park shelters bobcats, bald eagles, and fossils from a time when this land lay beneath the Pacific Ocean.
