Gordon Gulch (2590 m) lies within Arapahoe National Forest and is divided into Lower and Gordon Gulch 2. Gordon Gulch joins the North Boulder Creek about 16 km downstream from Green Lakes Valley (GLV)._ This site is underlain by biotite gneiss and is mostly forested. Different aspect slopes present contrasts in soils and vegetation: thinner, less-weathered rock with grasses and Ponderosa pine (P. ponderosa) on south-facing slopes, and thicker, more weathered rock with dense Lodgepole pine (P. cortorta) on north-facing slopes.

It is characterized by the low-relief remnants of a dissected Tertiary erosion surface in which weathered rock profiles are up to 15 m thick._
Gordon Gulch is within the montane climatic zone._MAP is 780 mm, 70% as snow.

All chemistry samples for major cations/ anions on the Thermo Scientific Dionex Ion Chromatography system in the Ecohydrology Laboratory. Hydrogen (dD) and Oxygen (d18O) Isotope samples were run on a Picarro Cavity Ring-Down Spectroscopy System in the Stable Isotope Laboratory, University of Colorado Boulder/Institute of Arctic and Alpine Research.
