An interesting lunar feature…

The Lunar Reconnaissance Orbiter Camera (LROC) got the following images which are shown on the northern polar mosaic at this link:

I became interested in an area at the edge of a crater named Plaskett near Plaskett U after watching this video: https://www.youtube.com/watch?v=BoiGz4hXgb8

At about 4.5 minutes into the video, the commentator discusses what looks like a road near Plaskett U in the area of the red rectangle shown below.

This area is most likely on a slope so this “road” feature may be from rolling rock. The feature vectors away from Plaskett U and toward Plaskett. However, there’s some things that make me wonder about this…

The “road” has a geographic feature at both ends. It starts from a tall structure, which may not be too peculiar if this was caused from gravity. If it is from a rolling rock, it could have ended in countless other locations. However, it ended at a crater. A light colored object appears at the end of the feature near the small crater. Perhaps that rolled and caused this. That seems like the most likely cause, but I’m not sure so I think this is interesting.

The “road” extends from the upper left of the photograph to the lower right. I don’t know how tall the feature on the lower right is, but it casts a shadows that is significantly larger than anything else in the area.

The feature appears to have received an impact after it was made.

Another possibility is this is collapsed lava tube, although this is straighter than examples of ballistic lava flows elsewhere on the moon.

  1. Hi there Jeff,
    I saw the same video and looked for the website with that map. After finding the “roads” that are on the video, I also found another area with many more “roads”. The slope of the ground and the direction of the “roads” imply that they are not from rolling rock. Maybe I’m just looking at them wrong, but IMO, they don’t look like they’ve been made from rolling rocks.
    I’m not sure how to post a picture for you, but I can describe how to get there.

    Go to Plaskett U. The same place as you have in your image. Follow the line made from where the image has been stitched upwards to the next obvious outcrop. There are multiple “roads” heading from there, leftward (in the image) along the slope – not down the slope, to multiple other craters.

    Again, they could be rocks rolling along in adverse ways. Still, it’s very interesting.
