Relative position Johnston Creek is a headwater tributary of the Feather River. The creek rises on the southwest flank of the Kigluaik Mountains and parallels the uppermost course of the Feather River, which is the next stream to the west. The location given is the approximate midpoint of placer mining claims shown as Kardex site Kx 52-87 of Heiner and Porter (1972).

Comments on the geologic information

  • Geologic Description = Johnston Creek occupies a glacial valley on the southwest flank of the Kigluaik Mountains. Placer mining claims have been located on the creek (Kardex site Kx 52-87, Heiner and Porter, 1972), but placer gold deposits are probably of river-bar type and transient in nature. Bedrock in this area is mostly amphibolite facies metasedimentary rocks (Sainsbury, Hummel, and Hudson, 1972; Till and Dumoulin, 1994; Hannula and others, 1995).
  • Age = Holocene.
