Field trips of our chapter

Saturday, November 5, 2022, 9:00 a.m. - 12 noon: BIg Tujunga Wash near Orcas Park: Where the dry, rocky flood channel of Big Tujunga Wash approaches Hansen Dam basin in northeast San Fernando Valley, deep groundwater is forced to the surface and supports a vast riparian woodland, infrequently visited except by local equestrian riders. Join Richard Rachman for a 3-hour tour of riparian and upland native plants near Orcas Park, focusing on the transition from dry to swampy soil conditions. Bill Neill will co-lead the tour for commentary on geology, 1920’s gravel mining, Hansen Dam history, and invasive plant control work since 2016. We will follow two miles of equestrian trails through the riparian woodland and along its upland margins, ending around noon. Our hiking route will be on mostly level and sandy trails, with several short rocky slope sections.

NOTE: This outing is sponsored by the Los Angteles/Santa Monica Mountains chapter of the CNPS.

Meet at the paved parking lot of Orcas Park, about 500 feet beyond the Hansen Dam Horse Park 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 on horse trails with several shallow-water stream crossings; bring optional picnic lunch and portable camp chairs for post-hike gathering at Orcas Park afterwards. For questions contact Bill Neill at bgneill@earthlink.net. Rain forecast will postpone event to Saturday, November 12.
