The periglacial areas were the best for grazing.
The wall of the glacier shielded the area from the bitter north wind, the dazzling vertical wall acts as a solar concentrator providing more heat and light for plant growth, the glacial till provides a rich, well conditioned soil, while moraines trap ponds of melt water.
Up near the face of the glacier is the best grazing for a thousand miles!
Until a big chunk breaks off and pounds you into the muck before you even have a chance to swallow that mouthful of marigolds...
Thumbs up!
