Putrid Ridge Spoils Spurr
south up image by " rel="nofollow George Tarsoudis, Greece
Here is an interesting stratigraphic problem to puzzle over. Palus Putredinus, the broad band of mare stretching
from the Apennines to Archimedes, interupts the band of older and rougher terrain to its north and south. The
truncation of the rilles paralleling the Apennines shows that the Putrid lavas are younger; they were probably
partially fed by Hadley Rille on the left against the mountains. I imagine that lavas fill an area that had faulted
downward as a giant graben. Near Archimedes is the small (D = 13 km) half crater known as Spurr. The crater
formed on an earier and lower surface, and its north rim was somehow destroyed by the last stages of Putrid
lavas. But what was the role of the broad mare ridge passing under or around Spurr? Is the ridge older or younger
than Spurr? Was it responsible for the loss of Spurr's western rim? Why did the ridge form?
