Printed on separate text page, TC: FRESH CRATER, Area near Kastner, 07°S, 84°E. The ejecta thrown out \ by the impact of a meteorite usually leaves a bright ray pattern radiating from \ the crater. This pattern is evenly distributed except for a 45° area, called a \ rooster tail, that marks the trail of the projectile that produced the crater. The \ rooster tail for this impact crater can be seen in the lower left hand quadrant. \ Other, older craters, darkened by the bombardment of space particles, \ can be seen in the area. These were formed by impact or by internal processes \ (volcanism or collapse). \ Craters that were produced by volcanic action can be identified by their \ hummocky (low, rounded mounds) floors, the ratio of depth to diameter, and \ by the nature of the surrounding lunar surface. Volcanic venting throws pieces \ of rock and ash or cinders into the air or discharges a bubbly or frothy form of \ volcanic flow which covers the surrounding area with a thin veneer of materials. \ Craters caused by collapse tend to be noncircular, do not have rim deposits, \ and the surrounding area is clean of volcanic or ejecta materials.
