Joni mentioned the other day, that in this ecosystem, the trees hold all the water. True. Since it doesn't rain for eight to nine months, the trees gobble up the moisture when they can---and hold it. All that water makes for some very heavy logs when building. Especially when you are relying on simple technologies (a tripod and pulley) to heft it into place.
We don't have a scale--so we can't really estimate how much it weighs.
Before the last long rafter:
Eight hours of work to get this into place. We got the rafter up on to the short side. We then pushed it to the middle. We put a rope on the front and then used the ATV to pull it up and over. We finally secured it with the tripod and finished putting it into place.
