According to the old Sami belief people could strengthen the spiritual bond between man and the forces of nature by offerings and respectful behaviour.
Sami offering stones, sieidis, and offering sites are often distinct nature formations, but may also be stone or wood formations erected or made by people such as the mentioned Ceavccageađge.
Everyday offerings to sieidis could be fish oil or fish guts, hunting and trapping products such as meat and blood, or small metal objects or coins. The offering was in accordance with what the offering was for and to whom you were offering.
Reindeer was the most common offering for special circumstances. The noaidi (a person with a special connection to gods and spirits, often described as the Sami shaman) could get exact information of what kind of animal the gods and spirits demanded as an offering gift.
