SHORT-NOTICE FIELD OUTING: Saturday, February 10, 2018, 9:30 a.m.: Hansen Dam Basin: Riparian habitat of Big Tujunga Wash: Leader Bill Neil, Grade: Easy, with several shallow stream crossings, 2 miles round trip.

The vast woodland of Hansen Dam basin is the largest and most natural riparian area within Los Angeles city limits, yet is infrequently visited except by local equestrian riders. This tour will view the aftermath of the Dec. 5-6 Creek Fire, plus the results of Arundo control funded by the National Forest Foundation, plus native plants that retain foliage in February.

Meet at the paved parking lot of Orcas Park, about 500 feet beyond the Hansen Dam Equestrian Center entrance, accessed from Foothill Blvd. via Orcas Avenue, about midway between the I-210 freeway exits at Osborne Street and Wheatland Ave. Wear protective clothing and water-repellent boots for hiking about one mile on horse trails with several shallow-water stream crossings. For more information contact Bill Neill at This hike may be repeated in June or in the fall when burned shrubs have revived.
