  <dc:description>&lt;p&gt;&lt;i&gt;Note: This paper is dedicated to Aaron and Elizabeth Waters on the occasion of Dr. Waters' retirement.&lt;/i&gt;&lt;/p&gt;&lt;p&gt;Several new chemical analyses of flows confined to a structural downwarp in northeastern Oregon indicate the first reported occurrence of Late-Yakima–type basalt in the region and the close stratigraphic association of Yakima–type and Late-Yakima–type flows, as well as andesite. The andesite is the most silicic flow rock yet found on the Columbia Plateau.&lt;/p&gt;</dc:description>
