Boulder Tracks

The Boulder Tracks thread is one of the most popular within the Moon Zoo forum and we have some amazing tracks posted there.

Boulder tracks are important to the Moon Zoo project – the following quote is from one of the Moon Zoo team members:

One of the main reasons we are asking Moon Zoo users to search for scars left behind by tumbling boulders is to help support future lunar exploration initiatives. Boulders that have rolled down hillsides from crater walls, or massifs like the Apollo 17 landing site, provide samples of geologic units that may be high up a hillside and thus difficult to access otherwise by a rover or a manned crew vehicle. If mission planning can include traverses to boulders that have rolled down hills, and we can track these boulders back up to the part of hillside from where they have originated, it provides a neat sampling strategy to accessing more geological units than would have been possible otherwise… Thus we hope to use Moon Zoo user data to produce a map of known boulder tracks (and terminal boulders) across the Moon. – Katie Joy

Recently ElisabethB (Els) posted the tracks shown below. Quite an amazing variety of track sizes and shapes! The track on the bottom appears to have mounds inside the track caused by the shape of the boulder that created the track.
Also, some of the tracks have craters overlapping them which may have been caused by the same impact. The original impact would have sent boulders bouncing and rolling along the regolith but would also have sent boulders upwards and they would have eventually fallen back and created craters.

The area where these tracks are found is Montes Alpes / Vallis Alpes.

    Nicely done Geoff. The boulder track mosaic photographs posted by Forum members have really evolved showing the tracks in great detail. One day we will simply click on a lunar map and see all the major boulder tracks in a given area compliments of MZ.

    Great work, Geoff ! I should also spend some time on this interesting project.
