I took this photo on California Highway 190, between Camp Nelson and Springville.
I’m not sure what the structure is, what purpose it serves or did serve. It goes on for quite a ways and looks like something to do with trains, but I think there are no tracks. Perhaps it was once a train track but has been decommissioned.
That, is the original wooden trestle flume system used for carrying water for the powerhouse. Here’s an article. http://m.recorderonline.com/flume-getting-needed-repairs/article_484d04ed-fa42-51e3-be38-405bafd1c665.html?mode=jqm
Thank you so much for this information, Tammi. Of course you would know, as you are stationed nearby. A co-worker had told me it was a flume (after I had scheduled the post), but I didn’t do any research. Your comment is much appreciated.
