English: Roofline of the Othniel Looker House, located at 10580 Marvin Road north of Harrison in Harrison Township, Hamilton County, Ohio, United States. Built in 1805 and the home of Ohio governor Othniel Looker, it is listed on the National Register of Historic Places. The snow on the roof is an example of solar gain — light snow had fallen overnight, and as temperatures were around freezing, sunlight melted snow but could not affect snow in the shadow of the chimney.
