The purpose of this project was to investigate a sample of the historic glass artifacts from three excavation sites in the Kittitas Valley: the Grissom Site (45KT301), the Robber's Roost Site ( 45KT800), and the Sorenson Site (no site number). I addressed five questions about the glass artifacts: 1) what was the minimum number of vessels, 2) what functional types of glass were found, 3) what technologies were used to manufacture them, 4) when, where, and which company made this glass, and 5) what Ellensburg stores or companies are represented in the sample. I also used the data to estimate the date of the historic component of each site.

A total of 1,247 specimens were examined from the Grissom Site. These represented a minimum of 40 separate vessels. With the Robber's Roost Site, a total of 982 specimens were examined and there were at least 463 separated vessels. There were 10 glass specimens and nine vessels from the Sorenson Site. All sample vessels from these three sites were made with either mold-blown technology or by a machine. Twenty-one glass manufacturing companies were identified from embossing: 17 companies were located in the eastern US. Three Ellensburg companies were identified from embossed glass. They were the D.O. Woodworth drug store (1889 - 1895), the Elwood drug store (1899 - 1936), and the Sody-Licious Beverage Company (ca. 1916-1949)-which later became the Ellensburg Coca Cola Bottling Company (1949- 1967).

The dates of the historic components of each site were between the 1840s - 1920s at the Grissom Site, around 1860 - 1970 at the Robber's Roost Site, and from the 1870s - 1920s at the Sorenson Site.
