I found some bright blood red lines (and thick) on one side of what appears to be a mountain top jutting up through the ice. The red line runs nearly the entire length of the side of the rock where it meets the ice. There is another red line near the center of the rock, nowhere near the ice. Very bright red and with fairly defined edges. Weird! Here’s the link to the “bottom” of the line. Follow it up for a few tiles. When it ends, move to the left one or two tiles and you’ll see another nearly perfect line on the rocks. At first I thought “blood,” but there’s way too much! My other thought was a red algae, but then why would there be some near the center of the rock/mountain peak?
Here’s the next set of tile up: http://www.tomnod.com/campaign/antarctica_pilot_2/map/10j5xky1l
And finally, here’s the red line on the rock/Mt. top: http://www.tomnod.com/campaign/antarctica_pilot_2/map/10j5xky1m
Edited: Here’s the second rock zoomed out. Looks like a giant club.
Edited: I found a 3rd rock with red. Notice the red is only on the right side of the rocks/mounts.
And a 4th rock (at the top of the map). http://www.tomnod.com/campaign/antarctica_pilot_2/map/10j5x18y1u
This last one has red on the snow, away from the rocks.
