Face checking in decorative maple veneered plywood panels is a significant
problem for hardwood plywood manufacturers, furniture makers, cabinetmakers, and consumers. Efforts made by panel producers and researchers to minimize checking conducted to-‐date have been limited, and produced contradictory results. In this study the impact of four manufacturing factors believed...

Late Cretaceous sedimentary marine and deltaic rocks of
Gabriola Island were mapped and studied during the summer of 1971.
Cretaceous strata constitute all the exposed outcrops on the island,
which is the northernmost of the Gulf Island chain of British Columbia.
The upper four formations of the Nanaimo Group are...

Approximately 4,210 feet of Late Cretaceous and 1,440 feet of Tertiary sedimentary rocks are exposed in the Salt Wells Anticline area of southcentral Sweetwater County, Wyoming. Late Cretaceous units include the Blair, Rock Springs, Ericson, and Almond Formations of the Mesaverde Group and the Lewis Shale; Tertiary units include the...
The Taylor-Windfall gold prospect, located in south western British Columbia, is hosted by Cretaceous tuffaceous andesites, underlain by granodiorite phases of the Coast Range Plutonic Complex. Mining exploration companies were attracted to the area because of low transportation costs, and a favourable geologic environment defined by high angle deep-seated faults,...

The northwest one-quarter of the Prineville Quadrangle is
underlain by Tertiary and Quaternary volcanic and volcaniclastic
rocks of the Columbia River Basalt Group, and the Clarno, John Day,
Rattlesnake and Deschutes Formations.
The Clarno Formation is dominated by pyroxene-bearing
andesites, but also contains olivine-bearing basalts, oxyhornblende-bearing
dacite and rhyodacite flows...

The history of fire between 1850 and 1977 in a portion of the
Willamette National Forest in-the central Western Cascades of Oregon was
documented using historical sources. Three types of records were
available: (1) records and writings not primarily concerned with fire
but yielding information about fire in context with...
