I've always been raised around country where the grass was beautiful and a rich part of the lives of everyone around me. Maybe that's why I find it so fascinating and elegantly beautiful in a very simple and classic way.
Yellowstone has experienced a longer and wetter than normal winter, so the grass has been slower to turn brown, causing more wildlife to stay around longer in the lower altitudes (this may be reason so many bear sightings and attacks have been higher than normal years).
Especially when they are back lit they show so much detail. This always reminds me of how Mesoamericans manipulated grass into a very useful grain - corn or maize. This became a staple for one of hte major civilizations of world history.
Each of the beginning civilizations had their own food source - all of them grain...Mayan/Aztec was grain; Oriental/Chinese was soy from the bean; and Egyptian was bread from grain.
But grass not only fed us, it provided other uses. Grass is usually the first type of plant to take hold of an area...like after a fire, it's grass that first comes back.
Grass is also a major source of food for animals.
Some grass has long stiff projectiles called beards that protect it from being eaten by animals.
Grass holds the soil together to prevent it from blowing or eroding away. This enables other vegetation to eventually take hold...bushes, shrubs, then trees if the climate allows.
Although this looks like amber waves of grain, or a piece of it in the purple mountains majesty, it's still elegantly classic as those amber waves of grain. Artist love this simplicity in design.
And then there's not telling what you'll find next!
