Monday 5 December 2011 - "Textured" Crater
« on: December 05, 2011, 07:46:07 am »
This week we highlight another image from the indefatigable kodemunkey. He posted a series of craters from the far side in the Interesting terrain thread on 17 November 2011 and I thought the textures from one particular crater were worth another look.

First an overview of the crater, which is on the far side and unnamed:


ACT-REACT Link: Lat=0.27 Lon=-123.7

An undistinguished looking crater, which is approximately 10 km in diameter and close to Hertzsprung H crater (part of which is in the bottom-left corner).

I’m not sure how the following “textured” features formed and am hoping one of the lunar geologists will help out!

First image is an overview of the textured surface and the remaining images are closeups.


M145434134LC





They look like they were created by someone dragging a large steel comb across the landscape, or a very strong wind (which doesn’t happen on the Moon!).

Great images from the indfatigable kodemunkey.

Thanks for putting this together, Geoff.

Beautiful example of ejecta scouring, where the horizontal momentum of impact ejecta creates this "combed" texture.

Thanks for that Irene, I wondered how that formed.
