| Notes | Lakes are natural sinks for sediments. Sediment cores from lakes can provide much information about their surrounding areas. Loon Lake is a landslide-formed lake dating from the sixth century C.E. In this Master’s thesis, the author reports on about 1500 years of information about the environment around Loon Lake derived from sediment cores. The sedimentary record shows several major earthquakes, including the 1700 event, as well as the influence of heavy logging in the period from 1939 to 1978. “The high mass accumulation rate and high concentration of thick event beds and layers during the early contemporary period point to the extraordinary role of timber harvesting in priming the landscape for subsequent sedimentary delivery during floods.” (from the Abstract) The major professors were Jeffery A. Hatten and Robert A. Wheatcroft. |
