As we have mentioned/hinted in recent posts, we are well into the great wall of Purgatory project. As Agent Smith noted last year, we were starting to think about replacing it and have posted about some of the preliminary work this past year, from having new topography maps done (from which we found out we’ve had just a half-inch of movement in the last 50 years) to proper soil studies done to ascertain the soil composition at deeper levels.
As part of the project we setup some cameras to capture time lapsed footage of the endeavor:

Thus we proudly present for you viewing pleasure the first month of work via the southern camera. You can view either the 1 frame per 30 second video at normal speed or at 20X if you’re in a hurry.
