Two simple questions for middle school research

1) What is the depth of lava beneath the surface of Archimedes?
2) Where do you find Helium 3 on the moon, and how is it extracted.

Archimedes crater is about 80km in diameter and should have a depth of about 4km (from the rim of the crater wall to the floor of the crater) but its current depth is 1.6km. It appears that lava from the Imbrium basin has filled Archimedes crater to a depth of 2.4km.

Helium 3 is found all over the surface of the Moon down to a depth of a few metres. It comes from the solar wind striking the surface of the Moon and being absorbed by the regolith. Earth is protected by its atmosphere and magnetic field so does not receive much, if any, helium 3.
