Umbraland Satellite Atlas

I agree with "landorl", mountains ranges are the result of tectonic overlap and collision, or volcanic upheaval in the case of a lone mount. Also, I did see some rivers that look as if they are flowing up hill.

I also spotted a tributary on the Northwest peninsula that flows counter to the main flow. That only happens if the river's course was carved by massive back flow like those of the grand canyon, and I don't see any geological evidence to support such.

I would add a small lake at the point where they meet, its more of a pack, but its also likely that such tidal forces impacting against each other would eventually carve a lake.
