Just wanted to show off the enormous stone wall we just finished yesterday. It retains the hillside next to our absolutely overbuilt and incredible clivus-multrum-style outhouse which is engineered to be partially earth-sheltered.
The wall was built with the pictured excavator and newly installed TILTROTATOR! It's taken quite a learning curve, but I'm really getting the hang of it now. We've even got a grapple for it, which grabs logs and moderately sized rocks wonderfully at damn near any angle at all!
