- The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford’s 1911 analysis, that J. J. Thomson’s plum pudding model of the atom was incorrect. Rutherford’s new model for the atom, based on the experimental results, contained new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume containing most of the atom’s mass; this region would be known as the atomic nucleus. The Rutherford model was subsequently superseded by the Bohr model.
- South Nemah Natural Resources Conservation Area (dnr.wa.gov)
This area is highly regarded as one of the last small uncut drainages in the Willapa Hills. Comprising 2,440 acres, it contains patches of 300-year old western red cedar and Sitka spruce and habitat for marbled murrelets and northern spotted owls. The South and Middle Nemah Rivers support fish and amphibian populations.
