Author Plot Code ? SAMO2544
Author Observation Code ? SAMO2544
Original Data Location ? SAMO NPS Headquarters, 401 West Hillcrest Drive, Thousand Oaks, CA
Location Fields: MAP: Google | Yahoo | TopoZone | MapQuest
Confidentiality Status ? exact location
Latitude ? 34.0747084650859 º
Longitude ? -118.516200850225 º
Author Location ? Topanga State Park
Location Narrative ? Fifty-plus percent of the area assessed, extends off of polygon boundary up the drainage to the NNW. Only tree cover assessed, understory not seen. Herb patches within polygon not really seen. Drainage has a NW to SE trajectory. The area in the center of the photograph taken is polygon 1x. Sight distance is approximately1000 meters (beyond distance of rangefinder). Unable to calculate UTM final because of inexact distance measurement. Added UTM final so that point would fall within correct GIS polygon according to overlay photocopy.
