Subject category Comment text
Deposit Discovery Year: 1860'S
Deposit GOLD IS IRREGULARLY DISTRIBUTED AND FINE GRAINED. GRAVELS WITH THE MOST GOLD ARE USUALLY CEMENTED WITH LIME
Deposit TEXT IN SHANNON (1922) SUGGESTS THAT DAY AND RICHARDS (1906) DATA MAY IN FACT BE FROM MIMADOKA AREA RATHER THAN FROM BLACKFOOT AREA. ALSO, G.A. DESBOROUGH HAS FOUND ESSENTIALLY NO PT IN SANDS FROM IDAHO FALLS TO POCATELLO (ORAL COMMUN., 1988) ; INFO.SRC : 1 PUB LIT
