Site numbers in the United States are based on the "Smithsonian Trinomial System" where each State has its own number (e.g., WA=45), the County within the state has a two letter abbreviation (e.g., Crook County = CR), and sites within the county are given numbers consecutively as they are found and recorded (i.e., 45xxnnn).
So, a site labelled as "45CR121" would be the 121st site recorded in Crook County, Washington.
