Both portals for the north tunnel (I'll have to think of an appropriate name sometime) are done. I spent some time on Thursday, November 9 and all morning today working on the Sierra Mountains portion of the Mojave Desert and Southwest Mountains.

In addition to pouring the portals, I poured a small retaining wall section for the west portal. I hauled dirt from an unused container garden in the west side on my yard to fill behind and cover the tunnel.

The main job today was filling the front side of the hill over the tunnel and sculpting the stream bed from the filter to the waterfall.

Maybe I will someday learn that concrete takes time to set. After I took this picture, had some lunch, did some assorted other things, I thought enough time had passed and I could start running water through the stream. Wrong! I ended up washing out the lip of the stream where it feeds the waterfall.

I had to spend some time this afternoon doing some concrete repair work.

While I had QuicKrete mixed I tossed up this stone retaining wall between the tunnel portal and water fall. I was going to knock off the excess cement, but by the time I got back to the wall the stuff was set up too hard to wipe off.
