Procellarum Volcanic Group

Procellarum Volcanic Group Volcanic structures on the Moon tend to be small and inconspicuous. Oddly, the three largest and most unique lunar volcanic landforms all occur along a meridianal belt in the northern half of Procellarum. From north to south they are Rumker, the Aristarchus Plateau and the Marius Hills. Nearby (mouse over to see where) is another smaller but also unusual volcanic feature - the steep-side Gruithuisen Domes. Rumker is a 60 km wide collection of coalescing domes. The Aristarchus Plateau has three peculiar features - it is a sharply bounded rectangular area (often considered an uplift) incised by Schroeter's Valley, the largest sinuous rille on the Moon, both with a dusting of pyroclastic material from the Cobra Head enlargement of the start of the rille. The Marius Hills is a collection of ~300 steep-sided domes and hills. The alignment of these three mega-volcanic features hints that they are inter-related but there is no understanding of how. Technical Details: Mar 16, 2003 21:00 UT webcam mosaic with the 4" TMB refractor at f/25; 200 images processed in Registax for each part; final levels and curves adjustment in Photoshop. CAW strongly enhanced the mouse-over image using an unsharp mask filter which brings out a purple colored halo that extends 200+ km beyond the Aristarchus Plateau - this is presumably pyroclastic mantling from the Cobra Head eruptions.
