Comments on the geologic information

  • Geologic Description = Fourth of July Creek (referred to as July Creek by Maddren, 1918) is a small stream that discharges into the Totatlanika River about one-half mile above the head of Murphy Canyon. The creek is incised in schist, and the lower half mile is narrow and bounded by steep walls 100 to 150 feet high (Maddren, 1918, p. 393). About one-quarter mile above the mouth of the creek, the schist is intruded by a dike that trends northeast across the gulch. The most profitable mining took place in stream gravels from below this dike to the mouth of the creek (Maddren, 1918, p. 394). Much of the gold mined from the creek was rough; some was attached to vein quartz . The largest nugget mined was worth about $25 (about 1.2 ounces) (Maddren, 1918, p. 394). Most of the mining took place in 1910 and 1911; total production owas$10,000 in gold (Maddren, 1918, p. 394).
  • Age = Quaternary placer.
