According to what I know about Moon nomenclature, this region is named 
after the Jura mountains in France and Switzerland, not after the 
Scottish island... and you're not looking north, but rather north-east, 
with Sinus Iridum (the large half-circular feature) to the right!

This is VERY interesting... how much RAM did the calculation of the 
mesh2 object (I suppose it is a mesh2 rather than a classical mesh - 
otherwise parsing would have taken almost forever) use? How many 
elevation points (i. e. vertices) did you use?

About two years ago I tried the same with ASTER Earth elevation data 
tiles (https://www.youtube.com/watch?v=R5pCZdj_VGM)... and had to limit 
the used elevation measuring points from the original 3601 x 3601 down 
to 2600 x 2600, as otherwise it would not have been possible with "only" 
16 GiB of RAM...

See you in Khyberspace!
