Not much left of Rowland! The site lies on the northward-flowing Bruneau River a few miles south of the Idaho line at a prominent water gap in deformed Paleozoic rocks, in which gold-silver mineralization is locally present, typically along faults. The main producer was the Bruneau (aka Rowland) mine. Mining activity extended from the early 20th century up to the mid 1930s or so. Because of the late date, I suspect the pulleys here were driven with gasoline engines rather than with water power from the Bruneau River, but there is a ruin of a low dam in the water gap. The left inset is a view a bit more to the left; the right inset shows a hopper and ore chute. The construction of the latter, in which finished boards are used for the sides but natural timbers for the posts, is a style more typical of the 19th or very early 20th century.
