All my life I have visualized the nasty winter wind blowing from the north. That's just how it is in all the books I've read. So I was very surprised to find in Westcliffe, and now in Cañon City as well, that the wind seems to mostly blow from the south. This is just not right.
The "bowls" are 2 large dirtwork water runoff catchments that the state put in when they expanded the roadways in the area. In a downpour, the runoff initially created some pretty deep crevices on the land. I guess somebody complained, and the state put in these earthworks.
The bottoms of bowls are below the level of the wind, so it's protected down in there. This might be a good place to plant. The only downside is that cold winter air will sink to the bottom and have no way to get out. Those trees could freeze their little tucheses off.
