Barbara and I returned to Santa Susana Pass State Historic Park for a second round (our first was wk260) on a new trail on a glorious fall day for a hike. The blue sky allowed a clear view SE across Chatsworth at one turn then NW into Simi Valley around another. A strong wind chilled the crisp air, and, aside from a few mountain bikers, we hiked alone on the entire trail that varied at almost every curve. The first quarter mile was a climb on a dirt trail, the second a descent on sandstone rock, then a short hop along Santa Susana Pass Road to begin a new climb edging the side of a deep drop down the mountain. Followed that to dirt paths, then a rock trail, and a rest stop on boulders. Located along the 118 just west of Chatsworth, the history dates back centuries to when the pass was a transportation corridor for the Fernando and Chumash Indians to and from villages and trading posts, then the 18th-century Spanish missionaries on ox-driven carts, 19th-century Mexican rancheros on horseback, American stagecoaches, and late 1800s RR companies looking for a fast lane for tracks between LA and SF.  The sandstone quarried here was used for the 1893 Southern Pacific RR pier in Santa Monica and in DTLA buildings as the city grew from a frontier town into a metropolis. A film site for early cowboy flicks in the 1920s, during the 1950s portions of the park were used as settings for TV westerns including Gunsmoke and Bonanza. This was an easy hike with enough variety to keep us entertained.
