The Marys River Fir site was established in 2006. It is located in a Douglas-fir stand planted in 1976, in the Oregon coast range near the town of Summit. The tower is 40 m tall and equipped with a full complement of eddy covariance instrumentation and a vertical profile of CO2 and meteorological data collection. The site is also equipped with a horizontal array of instrumentation collecting data on temperature, soil respiration, sapflow, and tree growth, and contributes data to the CO2 concentration project. The site is powered by solar panels and a backup generator.
