Crossdating by skeleton plotting
A large wooden sign marks the entrance to Pack Forest at our gatehouse on Highway 7.There is limited parking at the gatehouse and the arboretum for trail users.Here, anomalous growth is plotted on a 2mm grid and up to 120 years are plotted on a single row with a maximum of 7 rows (840 years).The 26th Annual North American Dendroecological Fieldweek (NADEF) will be held at the Pack Forest Conference Center at the Center for Sustainable Forestry in Charles Lathrop Pack Experimental and Demonstration Forest.The skeleton plot is made by calculating departures from high frequency growth for each year by comparing year t to the surrounding three years (t-1,t,t 1). Relative growth is scaled from one to ten but only values greater than three are plotted.This function's primary effect is to create plot with absolute units that can be printed and compared to other plots.Note that this plot is a standard plot in dendrochronology and typically made by hand for visually cross-dating series.This type of plot might be confusing to those not accustomed to visual cross-dating. The implementation is based on Meko's (2002) skeleton plotting approach.
Take I-405 North “Renton” exit then take the Hwy 167 Kent exit South.
Take Exit 127, and follow Highway 512 for about ¾ of a mile.
Take the first exit for Steele St and turn left onto Steele St. Continue for about 5 miles on Steele St/Spanaway Lake Loop Road.
Horse trailers should park in the large gravel lot about ¼ mile North of our main entrance near the junction of Highway 7 and Highway 161.: Fly into Seattle-Tacoma International Airport (SEA) which is about an hour and half drive away from the field station.
We will meet you at the baggage claim and have vans to bring you out to the field station.
Your registration fee includes registration, room, and board for the entire week.
