This is a stand that the tripod [laser] would mount to and this is what anchors itself into the ground [pointing to the tripod's feet]. Also is a grade rod and detector.

U106 is defined as R1b1b2a1a by Family Tree DNA. U106 subclades include R1a1b1b2a1a1, R1a1b1b2a1a2, R1a1b1b2a1a3, and R1a1b1b2a1a4.â.
Some say freckles come from the kiss of an angel. But we know where most of them really come from. They come from genes. And the sun. Freckles are spots usually seen on people with fair or light skin. These spots contain melanin, a pigment protein. Melanin gets made when harmful ultraviolet (UV) light from the sun hits our skin. This UV light is very powerful and can damage DNA. Melanin shades and protects our DNA from the sun.
