Rock Axles

Here's some stone age ingenuity for you! I was watching some annoying guy on either TLC or Discovery who trekked through the Mid-East following the Bible. This particular episode explored how in ancient times around the region of Israel, people would move giant slabs of rock by using it as an axle between wheels. After the rocks were transported to their destinations, they were used to build buildings. Pretty neat! How's that for using the 'ol noggin!
