Additions To The Late Tertiary Floras Of The Pacific Northwest, George F. Beck
All Faculty Scholarship for the College of the Sciences
The purpose of this paper and those which will follow, is to present new types of flora found in several older leaf localities of the Pacific Northwest. A study will also be made of a number of new localities as yet not reported upon in the literature. The present paper refers to several new species found at the Bull Quarry, Ellensburg, and the Brickyard locality, Spokane, Washington. Both sites have been studied and reported upon in the past, as noted in attached bibliography.

Washington Petrified Forests-Ginkgo Exotic Forest, George F. Beck
All Faculty Scholarship for the College of the Sciences
Seven years ago we began our study of the Ginkgo Petrified Forest in Central Washington. This is in reality a series of forests occurring at various horizons in the Yakima ( and Wenas?) basalts throughout a vertical range of some 2,000 feet, and in a belt 150 miles long, and 50 miles wide, centering at Vantage on the Columbia River.

Determination Of Fossil Woods (Basswood In Ellensburg Formation), George F. Beck
All Faculty Scholarship for the College of the Sciences
From time to time isolated, rounded pebbles of petrified wood have been encountered in the Ellensburg gravels that overlie the Columbia Basalts in Central Washington. Recently a sufficient number of these specimens were collected to justify a study of the petrified woods of this above-named formation.
