Hillshade Of South Mountain

As natural processes go, humans are one of the most notable on how they have re-shaped the surface of the earth. Graded surfaces, such as roadways and carriageways are clearly visible on this LiDAR Hillshade along South Mountain and the Palenville Clove of the Catskills. Old carriageways, long abandoned or converted into hiking trails might not be visible on normal aerial photography, but still show up on this hillshade of the landscape. Zoom in and take a careful look at this image.
