Eight series of untreated posts (including five series of steel), 18 series of nonpressure-treated posts, and II series of pressure-treated posts remain in test at the Oregon State University post farm in western Oregon. So far all posts have failed in 36 untreated series, 33 nonpressure-treated series, and 2 pressure-treated...
Untreated and preservative-treated fence posts were exposed in soil at a test site near Corvallis, OR. Several species, including western juniper and Osage-orange, showed exceptional natural durability. Preservative treatment generally extended the useful life of the posts, but the degree of protection varied with the chemical and the application method.

The Amsterdam-St. Paul Plateau is bisected by the intermediate-rate spreading Southeast Indian Ridge, and numerous geophysical and tectonic anomalies arise from the interactions of the Amsterdam-St. Paul hotspot and the spreading center. The plate boundary geometry on the hotspot platform evolves rapidly (on timescales <1 Myr), off-axis volcanism is abundant,...
