Thelogo of the Church of Spiritual Technology, the Scientology-associated non-profit that maintains, archives, and controls the copyrights on materials written by Scientology founder L. Ron Hubbard. One of the aims of the CST is to maintain a long-term archive located underground in Trementina, New Mexico. The above emblem is engraved in large scale in the ground over the vault, ostensibly to aid in the location of the vault in the furture.
