Jamnikov spodmol je manjša jama pod skalno steno v kateri so bili odkrite sledi, ki kažejo na to, da so jamo nekje v času med 9.000 in 6000 let pred našim štetjem obiskali takratni ljudje. V jami je bila najdena koščena harpuna, kremenov odbitek in nekaj fragmentov zob rjavega medveda. Najdbe so bile na podlagi analize oglja in koščene harpune umeščene v kulturo srednje kamene dobe oz. mezolitika. Skupaj z najdbami kamnitega orodja na Belškem polju pod dolino Poljane, kjer je Jamnikov spodmol so to najstarejši dokazi človekove prisotnosti v Gornjesavski dolini.
Jamnik rock shelter (Jamnikov spodmol) is a small cave under a rock wall. Traces discovered in the cave indicate, that somewhere in the period between 9000 and 6000 BC the cave was populated. Researchers found a bone harpoon, a flint fragment and a few fragments of brown bear teeth. The analysis of the charcoal and the bone harpoon place the findings in the Middle Stone Age or Mesolithic. Together with the stone tools found in the field Belško polje, that lies under the valley of Poljane, the findings of Jamnikov spodmol are the oldest evidence of human presence in the Gornjesavska valley.
