Atlas

Hercules 39.1" E 46.7"N Atlas and Hercules are prominent pair of craters near the north-east limb. Their walls look similar but their interiors are very different.

Atlas is 87 km in diameter, with a small central peak and terraced walls rising to about 3000 m. Its rough floor contains two fairly dark patches and a complex fracture of rilles (Rimae Atlas) which are believed of volcanic origin.

Hercules is a terraced crater with relatively flat floor, 69 km in diameter. It has a lava-submerged central peak

and contains the bowl-shaped Hercules G, easily seen in small telescopes. A small crater, Hercules E, is on the southern wall.

Bürg 28.20 E 45.00 N Bürg is a prominent sharp-rimmed crater in Lacus Mortis (Lake of Death), 39 km in diameter. It has a large central peak. Its high terraced walls contain deep clefts. Bürg's ejecta blanket can be seen thrown out into two main swaths heading north and south from the impact zone. Between these swaths of material are two rilles (Rimae Bürg) that intersect roughtly at right angles. The two rilles add up to 140 km in length.

Mason 30.50 E 42.60 N Plana 28.20 E 42.20 N Manson and Plana are overlapped flooded craters. Mason is 33 X 43 km. Plana is 44 km in diameter with a central peak.

Grove 32.90 E 40.30 N A crater, 28 km in diameter. Its ejecta blanket resembles that of Bürg.

Daniell 31.10 E 35.30 N An oval crater, size 23 X 29 km. In its west is Rimae Daniell, a system of straight rilles up to 200 km long.
