Here is my compost pile, hidden from the neighbors by evergreens on two sides, and kinda-sorta hidden from my view by a chain-link fence. Yesterday we needed some of the really good stuff from the bottom to use in one of the raised beds. I shoveled back the layers of grass clippings and newspaper that I had added this week on Tuesday or Wednesday and beheld an impressive sight.
On a day of perhaps 60 degrees in the shade, I had dug into the hot cooking core of a 150 degree compost pile. Watching the steam rise was quite impressive and I called over the kids and my wife to all have a look and feel it. H. was very impressed that this actually happened naturally, and had the sudden realization that a big component of all dirt everywhere was rotted dead things. 🙂
