the first one seems an installation of some sort, with a cilindric aerial and a strange structure possibly spheric, partially obfuscated by a rectangular withe shape that in my op has been put on it on pourpose.
in other words, that rectangular white shape seems to be "over" the structure more than "part of" the structure, or in alternative you have spotted something really strange.
in any case it's artificial, very good sight, like the other one you spotted in Tycho crater.
the second one gives to me the impression of like big lavic rocks, indeed with strange shapes and with courious positions, like in junction.
maybe a craft fossilized, or just a trick of the eye.
The following slides show a grouping of objects which together have provided an interesting and new area of study for me. The first slide shows the location at the maximum magnification provided online by the LROC Quick map site at 0.5metres per pixel. The second slide sees the same area magnified and turned 180 degrees. The 'shuttle shaped' object or objects central to this posting appear in the top right hand corner of the boulder field. In a boulder field Shadows and light throw strange and confusing shapes upon the ground but a reasonable amount of detail can be seen in slide 3. A comparison of the Quick map image has been provided by M168088244L. If the 2 images are compared a slight variation can be seen in the sharpness and blending of the pixels. The M image also appears to be slightly elongated in comparison to the Quick map image. 2 other images of the location do not show the object clear enough to make any sort of comparison. Slide 4 shows a couple of anomalies which are situated nearby to the main 'shuttle shaped' object which itself seems to have some very strange shapes on top which look almost crane like. Slide 5 shows an anomaly in a small nearby crater.
