Question: Alfred Wegener, the German polar researcher, had an impact crater named after him where?

Context paragraphs:
Isabella (crater): Crater Isabella is the second largest impact crater on Venus.  The feature is named in honor of the 15th Century queen of Spain, Isabella I of Castile.  Located at 30 degrees south latitude, 204 degrees east longitude, the crater has two extensive flow-like structures extending to the south and to the southeast.  The end of the southern flow partially surrounds a pre-existing 40 km circular volcanic shield.  The southeastern flow shows a complex pattern of channels and flow lobes, and is overlain at its southeastern tip by deposits from a later 20 km diameter impact crater, Cohn.  The extensive flows, unique to Venusian impact craters, are a continuing subject of study for a number of planetary scientists.  It is thought that the flows may consist of 'impact melt,' rock melted by the intense heat released in the impact explosion.  An alternate hypothesis invokes 'debris flows,' which may consist of clouds of hot gases and both melted and solid rock fragments that race across the landscape during the impact event.  That type of emplacement process is similar to that which occurs in violent eruptions on Earth, such as the 1991 Mount Pinatubo eruption in the Philippines.

Ritchey (lunar crater): Ritchey is a small lunar impact crater named after the American astronomer George W. Ritchey.  The crater is situated to the east of Albategnius in the central lunar highlands, it is also northeast of Burnham, and west of Andĕl.  Its somewhat angular rim is broken along the northwestern wall by a pair of smaller, adjacent craters.  The floor of Ritchey is fairly flat, with a pair of small central mounds.  North of Ritchey is a satellite crater known as Ritchey F, its southernmost rim is only hilly and is almost missing, its elevation is nearly the same as the main crater.

Wegener (Martian crater): Wegener is an impact crater in the southeasternmost area of the Argyre quadrangle of Mars, located at 64.6°S latitude and 4.0°W longitude.  Wegener is also in the northwest of Sisyphi Planum.  It measures approximately 68.5 kilometers in diameter and was named after German geophysicist Alfred Wegener (1880–1930).  The name was approved by IAU's Working Group for Planetary System Nomenclature in 1973.

Dalgaranga crater: Dalgaranga crater is a small meteorite impact crater located on Dalgaranga pastoral station 75 km west of Mount Magnet (or north of Yalgoo) in Western Australia.  It is only 24 m in diameter and 3 m deep, making it Australia's smallest impact crater (with exception of the smallest members of the Henbury crater field).  Though discovered in 1921, it was not reported in the scientific literature until 1938.  The bedrock at the site is weathered Archaean granite of the Yilgarn Craton.  The discovery of fragments of mesosiderite stony-iron meteorite around the crater confirms an impact origin, making this crater unique as the only one known to have been produced by a mesosiderite projectile.  Asymmetries in the crater structure and the ejecta blanket imply that the projectile impacted at low angle from the south-southeast.  The age is not accurately constrained but must be young because it is so well preserved for its small size, and the meteorite fragments have not weathered away; some authors suggest an age of as young as 3000 years.

Amelia Creek crater: Amelia Creek crater is an impact structure (or astrobleme), the eroded remnant of a former impact crater, located in the Davenport Range, Northern Territory, Australia.  It lies within a low range of Paleoproterozoic sedimentary and volcanic rocks, which are extensively folded and faulted, thus making an eroded impact crater difficult to recognize.  It was only discovered by the identification of shatter cones near its centre.  The central shatter cone locality is surrounded by a 20 by area of anomalous deformation, the asymmetry being possibly related to very oblique impact, but may be at least partly due to the pre-existing structural complexity of the rocks.  This deformed zone gives the best estimate for the original size of the crater.  Impact took place after folding of the Paleoproterozoic rocks but before deposition of Neoproterozoic and Cambrian rocks which overlie them, thus constraining the impact event to the interval between about 1660 and 600 Ma.

Wegener Canyon: Wegener Canyon ( ) is an undersea canyon named for Alfred Wegener.  Name proposed by Hans Werner Schenke, Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany.  Name approved 7/89 (ACUF 233).

Cornelia Lüdecke: Cornelia Lüdecke (born 25 November 1954) is a German polar researcher and author.  A leading figure in the history of German polar research and the history of meteorology and oceanography, she founded the Expert Group on History of Antarctic Research within the Scientific Committee on Antarctic Research (SCAR), institutionalising historical study and reflection for the Antarctic scientific community.  Her books, among others, about the Schwabenland Expedition to Antarctica during the Third Reich and "Deutsche in der Antarktis" (Germans in the Antarctic) are milestones in the history of polar research publications.

Reinhold (crater): Reinhold is a prominent lunar impact crater that lies to the south-southwest of the crater Copernicus, on the Mare Insularum.  To the northeast is a small crater named Fauth, to the east-southeast is Gambart, and to the southwest is the slightly smaller crater Lansberg.

Alfred Wegener: Alfred Lothar Wegener (none }}  – none }} ) was a German polar researcher, geophysicist and meteorologist.

Otbah (crater): Otbah is an impact crater on the southern hemisphere of Saturn's moon Enceladus.  Otbah was first observed in "Cassini" images during that mission's March 2005 flyby of Enceladus.  It is located at 39.8° South Latitude, 159.5° West Longitude, and is 9.4 kilometers across.  A smaller impact occurred after the Otbah impact on the larger crater's southern rim, forming an impact crater 3 kilometers across.  In addition to subsequent cratering, southwest-northeast trending fractures, prevalent in this region of Enceladus, cut across Otbah, forming several canyons several hundred meters deep along Otbah's rim.  The high level of tectonic activity associated with this fracturing and the formation of the nearby south polar terrain may have also led to mass wasting along the crater's wall, leading to a 3 kilometer wide landslide deposit in the center of Otbah.
