For the foundation for this outhouse I drilled about a foot deep through solid plate rock and then added lag bolts. Then I cemented them in to the rock so if the wind takes this outhouse then it will have its work cut out for it. I used up the last bag and a half of concrete to pour a foundation, but could have used another bag, but wasn't going to go back to Alpine (58 miles) to get one. I'm sure it will do even if it does look like a crappy job. It is! I used most of the ice melt water I've been storing up for it and the swivel for the wind generator so will have to start saving that up again before I start pouring more concrete next time.
I got the 12x20 tarp put over the guest house and hopefully secured enough to keep the tent down and stay in place. If need be I'll drill more places for stakes to anchor it and pound in more stakes for the tie downs. Should do the trick?
Last is a view from here early this morning. It did get partly cloudy later (mostly sunny, but is starting to get more clouds popping up. Hopefully for me no rain tonight, but I'm sure that those who are already setup for water catchment it would be nice.
