Bjørnberget ligger sør for Damvatnet. En 8 m lang, 2-3 m bred og opptil 2 m høy stoll er drevet mot sørøst (135°) i bunnen av brattskrenten på nordsida av Bjørnberget. Svak disseminasjon av magnetkis og pyritt finnes i mørk, skjærdeformert kvartsfyllitt med enkelte kvartslinser i cm-skala. Den tilnærmet flattliggende sonen kan følges i minst 30 m langs skrenten. Skrenten er gulfarget av svovelutfelling over en bredde på 7-8 m, men det er lite sulfider å se i fastfjell.
