Saturday, June 16, 2018, 8:30 a.m.: Hansen Dam Basin - Riparian habitat of Big Tujunga Wash: Leader: Bill Neill. Grade: Easy. Duration: 90 minutes to 2 hours.

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 Creek Fire of December 5-6, 2017, plus the results of Arundo control funded by the National Forest Foundation, plus a variety of riparian trees and upland native plants.

We will 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 (not sandals) for hiking about one mile on horse trails with several shallow-water stream crossings. Restrooms are located near the parking area. For more information contact Bill Neill at
