Five carved blocks have been found in Group A at Yo’okop. The carved stones are likely from the same building due to their similar carving depths, glyphic compounds and cartouche formats (Wren, et al. in press). It is believed, based upon a local informant, that the known carved blocks (roughly 0.4 x 0.4 m) originated in the same structure, although they were found elsewhere in Group A.
This apparently important building is Structure S5E1-1 which measures 50 x 50 x 11 m. It is an unusual building since it has a square base and inside this square is a depression with a pyramid in the middle. It resembles a smaller version of Tikal’s South Acropolis. The moat could potentially be the result of a collapsed substructure. This building connects the pyramidal structures in the western part of Group A with an area dominated by range structures to the east (Shaw, et al. 2000).
The carved blocks at Yo’okop were probably stairway raisers (Wren and Nygard 2005:170-171). Stone B may include the name Sky Witness, or ruler 17 from the Kaan kingdom (Martin 1997:861). It may have been carved during or later than his reign. He may have come to power around A.D. 546, but he reigned at least A.D. 561-572 (Martin and Grube 2000:102-104). Stone B is probably a posthumous reference to this ruler. Yo’okop was an important site that connected sites in the Southern and the Northern Lowlands along the so-called Petén corridor that runs northward towards Coba.
Stone C may describe a royal woman; “the kaloomte’ Ix Ch’ak Kab”. It is believed that she came from the Kaan kingdom (Wren and Nygard 2005:174-176). Stone F’s upper right glyph block may have the phrase u kahi (“by his doing” or “under the auspices of”) (Shaw, et al. 2000:58). This last glyph could possibly imply a hierarchical relationship to another site, most likely Dzibanche in the late Early Classic/early Late Classic Kaan kingdom (Shaw, et al. 2000:58; Wren, et al. 2001:101).
As the earlier posts on the Kaan kingdom shows, the Early Classic Snake kings appears to have gain strengths in the east and northeast before they moved the capital to Calakmul, back to an area near where the kingdom may have originated in the Mirador basin during the Late Formative. Yo’okop appears to have been part of this process since the site probably was an ally/vassal to the Kaan kings. The largest single construction at Yo’okop, Sacbe 2, appears to have been constructed during this time. Before any excavation one can only speculate that the person buried in the pyramidal mound where the causeway ends came from the Kaan kingdom, maybe the person mentioned on Stone C, or at least someone associated with that person.
