Charles Pack Forest
Pack Experimental Forest site is located on the Charles Pack Experimental Forest
station, operated by the University of Washington. The site is located about 5 km
southeast of Eastonville, Washington.
With help from SCIGN and UNAVCO, we installed a smaller, hand-drilled geodetic
monument, known as the short drilled-braced geodetic monument. The monument
design is perfect for rapid installations of continuous GPS sites. Data collection started
on March 15, 2001.
CPXF is part of a radio telemetry (FreeWave) subnetwork that feeds into the Pierce College
hub. Click here to

It consists of 1-inch diameter stainless-steel rods forming a quad-pol that stands about 3
feet above the ground surface and is anchored 3 to 6 feet into bedrock. A generator-
powered handhelp rotary drill using a 1.5-inch diameter drill bit is used to prepare
the holes. Epoxy is used to anchor the stainless-steel rod in the holes.
