Inscriptions typed on applied label affixed to mount verso, TC: Lunar Orbiter IV - 24 inch Lens [underlined] \ High Resolution Photograph of Site 27.3 (KI-4139) [underlined] \ This photograph of the crater [underlined] Aristarchus [underlined], Schroter's [underlined] valley [underlined] and \ vicinity was taken vertically at a position of about 24°N and 49°W in lunar \ coordinates. \ Aristarchus is about 25 miles in diameter and 6900 feet deep. The \ rim is about 2600 feet high compared to the neighboring surface. The white \ portion of the crater is the brightest spot on the moon with an albedo of nearly \ 18%. In making this print, dodging was required to bring out the ray structure \ of the crater walls. This region has shown luminescence. \ The companion crater Herodotus is 22 1/2 miles in diameter and 4400 \ feet deep. \ The snake-like feature in the upper left is named Schroter's Valley. \ The detailed structure on the valley floor is ordinarily not seen in telescope \ photos from the earth. \ S/C Frame #150.
