These solar systems are navigated by star sheep and humans brave enough to risk turning an ankle. The suns themselves are self-woven by grass, maintaining heat by spherical, or hemi-spherical shape. Sub-arctic climates don’t exist at the level of the grass. Just in the vast interstellar distance between clumps. But that’s what star sheep are for.
Patterned ground is created near glaciers, where ground freezes and thaws dramatically. Stripes in patterned ground are created by slopes of 2 to 7 degrees. This is ice talking under the ground. Think of it as a balance between water …
… and frost.
In Iceland, life doesn’t just come from heat.
