Santa María Acapulco is one of the indigenous havens in which the cultural heritage pame has been preserved with more emphasis; their isolation and the uneven topography, they transform it into a refuge barely assisted by the state politicians of development. This town, together with those of the northeast of Querétaro, conform the last indigenous bastion of the contemporary southern pamería.

Language - The language pame or xi'ui, is a language that has ended up taking refuge in the domestic and family space. Spanish's preponderant paper as main vehicle of communication in all the social environments, the discrimination to which they are subject for the use of the pame and the obstacle that it constitutes for the insertion of the youths in the labor market, has contributed to the systematic abandonment of the language.

Housing - The indigenous houses are built with palm, adobe and wood. For the construction of a new residence the pames request help of two or three volunteers. The lots are traced on rectangular surfaces. The shacks, generally rectangular and with roofs of two slopes, made out of royal palm, tiles or sheet, they are sustained on pitches in the superior part with a timber that crosses the room one end to the other. They make the walls with bars of bushes, and cover with mud or with adobe.

Dress - The pames has substituted a great part of their old cultural elements, which is reflected in the dress that is used today. The men as the women dress with ordinary attires without any feature of its old traditional gears.

Party - The most important celebration for the pames is the Holy Week.

Social organization - Almost all the pames residents in Queretaro maintain close relationship networks; there is a rule exogámica among the males that forces them to go to Santa María Acapulco in search of a woman for the marriage. Santa María has been able to perpetuate an indigenous government's system, one that works with the municipality's capital, as well as with 16 homesteads. The officials direct the matters of civil and religious character. In each town the "faena" is carried out which is an obligatory community work. The family heads, men and women, contribute to the town a certain number of "faenas" along the year, as the maintenance or construction of roads, highways, schools, chapels, jagüeyes and reservoirs. If they cannot carry out this work, they pay so that another person makes it.
