Shoshe - lost

For the past few weeks, I've been looking at tons of images of one of my field sites, Cumberland Ridge, which encompasses three neighboring outcrops in the Columbia Hills (in Gusev Crater on Mars). I'm trying to correlate the locations of the outcrops by identifying the same rocks from several viewpoints. I know these outcrops and the small rocks around them REALLY well*. Now I'm looking at some images from a nearby site, and I don't know any of the rocks. It feels like I'm lost -- Tennessee Valley is just to the side like it should be, but I'm in this sea of rocks and I don't recognize any of them. It's really weird. Kind of...alien.

*By name, actually. Cadge is my favorite, but Buoy has really grown on me. It's easy to identify from just about any angle.
