The present-day visitor to Mound State Monument may see, on the 300-acre Monument tract, 40 mounds which are the remnants of the Moundville Indians’ great city. The visitor will be interested in identifying these mounds as _domiciliary_ (as distinguished from burial mounds and effigy mounds found at other Indian sites). These domiciliary mounds, which were erected as substructures for temples and other important buildings, are rectangular truncated-pyramids. Their sizes vary. The largest, called Mound “B” (see map), is 58½ feet high and covers almost two acres. Prehistoric Lakes The several lakes within the Monument area are restorations, made after considerable research, of prehistoric reservoirs. The forty- to sixty-foot bluff at the ancient city’s river front made the Warrior River an impractical source of water supply. These lakes, therefore, may have been used to catch and hold water for daily use and for fishing. ERSKINE RAMSAY ARCHAEOLOGICAL RESEARCH CENTER Already constructed through the generosity of Dr. Erskine Ramsay, Birmingham, Alabama, Honorary Chairman of the Board of Regents of the Museum, is a large and spacious laboratory building, in which all archaeological material comprising the Museum’s vast collection is suitably and adequately housed. Space is available for students to study any phase of the subject in which they may be interested. (See photograph on page 20.) Also completed in the Research Center is one cottage in which a married student might be housed during the period of his studies. Yet to be constructed are two cottages, a dormitory for unmarried students, and a house for the resident archaeologist.

The archaeological museum houses an exhibit hall and two _in situ_ burial groups. The exhibit hall makes up the main part of the building. The in situ burial groups are enclosed in wings at the north and south ends of the exhibit hall. Design. Design of the building itself was based on ideas used by the Moundville Indian in shaping and decorating his artifacts. The classic three-step motif expressed in the three roof levels of the museum, and used over the doorway, was a favorite design element of the Moundville artist. The skull and arm-bone design making up the parapet frieze was copied from a design on a Moundville Indian pot (_see photograph on p._ 11). The medallion over the entrance is an enlarged reproduction of a stone pendant once owned by a Moundville Indian (_see photograph on p._ 4). This pendant as well as the pot from which the frieze was copied may be seen in the exhibit hall. Main exhibit hall.
