Excavations in the 1954 season were confined to a relatively thorough examination of Group A-3 and Str. Q-62 and to spot digging in nine other structures. The spot digging was done at likely places for encountering tombs and cists noted during the survey and surface examination of the areas. R. E. Smith, as in the past, examined the collection of sherds and furnished for them the data given in this report. Of the 8,622 sherds recovered, 7,067 (98.6 percent) are of Mayapán period, 81 (1.13 percent) are of Puuc wares, and 1,474, due to weathering, were unidentifiable. Among the Mayapán sherds those from effigy censers number 1,410 and Fine Orange, 31. The highest percentage of Puuc sherds appeared in Lot A-140 (tomb beneath passageway of Str. AA-37). When complete contents of a Lot are not given under the description of a structure, they will be found in the caption of the drawing of the construction. Surface material recovered during the survey of Squares Y, Z, and AA not mentioned in the text but shown in Figure 17.8 as follows: b. fragment of lime-stone metate, unusual in that it has legs and is grooved, Lot A-104; e. copper bell, Lot A-94; f. fiber beater, Lot A-92; f. stone plug, Lot A-96. At the close of the excavations all pits and trenches were filled, in conformance with agreement with the Mexican Government. Str. Q-62 was solidified under the direction of Gustav Strömsvik. © 2009 by the University Press of Colorado. All rights reserved.
