High altitude view of the lunar surface was taken from the Apollo 8 spacecraft looking southward across the crater Humboldt toward the Southern Sea. Humbolt, located at 80 degrees east longitude and 28 degrees south latitude, is the 225 kilometer crater at the top center margin of the picture. Note the high albado along cracks in the floor of the crater. Visible structures within the dark areas on the crater floor suggest the dark material is lava. Dark areas near the lower left corner of the picture are more deposits within the Southern Sea.

High altitude oblique view of the lunar surface was taken from the Apollo 8 spacecraft looking northeastward. The crater Joliet-Curie, about 175 kilometers in diameter and centered near 94 degrees east longitude and 27 degrees north latitude, is near the center of the left side of this photograph. The bright-rayed crater near the horizon is probably located near 105 degrees east longitude and 45 degrees north latitude. Long, narrow rays that have been reported in the polar region of the earth-facing hemisphere may radiate from this crater.
