TMZ has learned the Pitkin County Department of Social Services is "aware" of the alleged incident between Sheen and his wife Brooke Mueller -- and the department is considering whether to pursue an investigation.
Sheen and Mueller have two 9-month-old children together -- and Charlie has two young daughters from his relationship with Denise Richards.
Officials at the PCDSS tell us, "When there is a domestic dispute and children are present in the home, we are always notified."
The official added, "If the family is vacationing in Pitkin County, and we feel that a thorough follow up is needed, we will contact the department where the family resides."
We contacted L.A. Child Services for comment -- but they refused to comment on the situation.
