Ring Muhly
When I saw the first grass ring, it reminded me of the rings we sometimes see in our desert. Old fire rings will cause plants to concentrate around the rocks forming the ring. Because the rings we saw in the Great Sand Dunes were so numerous and so close together, I suspected something else must be causing it to grow this way so I asked the ranger about them. I learned the grass is Ring Muhly which grows in a tight ring forming a well, of sorts, in the middle to catch rainwater. Pretty amazing survival tactic!
