Till (Wikipedia) Till or glacial till is unsorted glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes.
The majority of soils in the [Georgia] depression are formed from glacial till, glacial outwash, and Lacustrine deposits.
Most till consists predominantly of clay, silt, and sand, but with pebbles, cobbles, and boulders scattered through the till.

When the vulnerability of, or threat to, specific classified information was exceptional, and the normal criteria for determining eligibility for access to classified information were insufficient to protect the information from unauthorized disclosure, the United States could establish Special Access Programs (“SAPs”) to further protect the classified information. The number of these programs was to be kept to an absolute minimum and limited to programs in which the number of persons who ordinarily would have access would be reasonably small and commensurate with the objective of providing enhanced protection for the information involved. Only individuals with the appropriate security clearance and additional SAP permissions were authorized to have access to such national security information, which was subject to enhanced handling and storage requirements.
