Alpha's 2nd pyramid sat on this concrete pad just West of Scott Engineering Center until later 2023, when it was disassembled. It was moved here from its original location, near Richards Hall, in 1968. Notably, the pyramid was not disassembled for the first move, but instead steel beams were placed below the slab, and the whole structure was lifted onto a truck and moved to its new location in one piece. Hand-drafted plans detailing the lifting operation can be found in the Sigma Tau trunk which is shown below. 

Buried in the cornerstone of Alpha Chapter's monument is a time capsule containing those items which in 1954 were believed to be of interest to future discoverers. The design of John Peterson, Arch. E. '53 was used with some revisions, notably a floating slab rather than deep footings. This not only reduced cost but has paid a substantial dividend recently by permitting the moving of the monument to new location to make way for a building which will shortly occupy the site. A limestone surfaced pyramid rests on a black granite square which is a part of an eight-pointed star. The rail section, donated by the Union Pacific Railroad, was the heaviest then in use and, like the projecting letters on two sides, is bronze-plated steel. One feature of the building program was the construction of a full-scale cardboard mockup which was tried in various locations preceding final selection of the site. The cost was held to about $3,000 for the completed monument by the work of the active chapter who did the actual construction. The dedication on November 11, 1954, and the unveiling by three of Sigma Tau's founders, Davidson, Hege and Stevens, was one of the features of the Golden Anniversary Conclave.

Alpha Chapter possesses a wooden Sigma Tau trunk which is full of records and various articles. One of the most noteworthy is the this record book, which dates back to the very first organizational meetings when the idea of Sigma Tau first arose in 1903.
