The rock shelter is located in the municipality Tocancipá, Cundinamarca, Colombia, in the northern part of the Bogotá savanna.
At Tibitó, bone and stone tools (knives and scrapers mostly) and carbon have been found.
The alcove's roof is about 50 feet (15 m) above the river, with the rock floor of the alcove at about 4 feet (1.2 m) above the river.
