Autumn Elm
You can live a long time in one place and still make discoveries. Yesterday's discovery was just how many American elms there are around here. American elms used to be common as they were the preferred tree for city planting in the 19th century due to their shape and color. And they are beautiful trees, large, majestic, everything a tree should be.
I assumed for quite a while that elms were pretty much a threatened species well on their way to being extinct thanks to Dutch elm disease which ravaged the population. Dutch elm disease and the monocultivation of elms is Exhibit A in why diversity of planting is a good thing. Diversity provides built in resistance.

The elms outside my window have been providing quite the autumnal show. Their leaves turn a lovely yellow orange which is a shade different than the orange yellow of the cottonwood. Maybe it is some combination of the right amount of moisture and temperature this year but I do not recall such a display before. I've been enjoying the view, so much so that when I get stuck on a problem or need a short brain break I go outside and look at the elms.
Yesterday was a golden October day. The leaves were still in full color and the temperature was in the 60's. Knowing such days will become less frequent I took advantage of it and went for a long walk on one of the wooded islands on the Missouri River. My destination was the furthest point on the island, a distance of about two and half to three miles.

I hope to find more elms in my knocking about the grasslands. According to the wikipedia article about the American elm, wild elms may have a natural resistance to Dutch elm disease. I hope so as I now feel very protective of the elms.
