Secret Town Trestle West 39°09'38.4"N, 120°52'38.58"W
Hart took three photographs of the Secret Town Bridge, which was a magnificent example of the elaborate trestlework that originally carried the railroad. These bridges were liable to rot and decay and had either to be replaced by bridges of stone or masonry or filled as is the case here.
Shearer p. 251 “Between Gold Run and Cape Horn Mills the road crosses Secret Town Ravine. There was formerly a station at this point. The high embankment covers a curved trestle work 1,100 feet long.”
“The ravine was named from its early history to mark the efforts of a company of miners to conceal their rich discoveries.”
