A map of the impact area. The ellipse does not represent the formal uncertainty, it just indicates the approximate area and the direction of approach. I am assuming that Daniel Estevez's analysis did not take into account actual topography and just assumed a spherical Moon, so the along-track dispersion could be larger than this suggests.

Andrew Jones tweets a drive distance of 33 m and a total of 271 m for day 8 (I have to work really hard not to write 'sol 8'). Two images are released, one showing tracks, the other taken with a high sun and showing bright crater rims. It looks southwest. The big crater with a few visible blocks might be the large sharp-rimmed crater shown in the latest route map, but I am not sure yet. If it is, most of the 33 m must have been driven early in the lunar day and only a bit after this was taken. I think. More information might overturn my speculations.

Here is the crater image in a rough perspective view:

A very detailed analysis of the Longjiang 2 impact location:

Below, an attempt of impact location according to Estevez's grayscale image from this article.

There is a drive log for lunar day 8 HERE.

(That's a horrible URL, there must be a more direct way to link to the site).

Yutu 2 drove mostly to the west but turned off the path, probably to the southwest, to investigate a small very fresh crater which had an unusual object in or beside it. Sounds like a blob of impact glass. Then they backed up a bit, away from the crater.

I got this from here:
