Abstract

Snow Water Equivalent (SWE) was measured using a calibrated scale, including the mass of the tube (units: cm).

For north-facing aspects, “downslope” refers to the area between the lowest snow pole and the second-lowest snow pole, while “upslope” refers to the area between the highest snow pole and the second-highest snow pole. For south-facing aspects, data were collected between the two snow poles, and the upslope/downslope distinction is left blank.

Location: Gordon Gulch (GG1 = lower, GG2 = upper), Arapaho National Forest, Colorado (~2590 m). Gordon Gulch joins North Boulder Creek about 16 km downstream from Green Lakes Valley (GLV). The site is underlain by biotite gneiss and is mostly forested. Contrasting slopes produce differences in soils and vegetation: thinner, less-weathered rock with grasses and Ponderosa pine (Pinus ponderosa) on south-facing slopes, and thicker, more weathered rock with dense Lodgepole pine (Pinus contorta) on north-facing slopes.

The area is characterized by low-relief remnants of a dissected Tertiary erosion surface, with weathered rock profiles up to 15 m thick. Gordon Gulch lies within the montane climatic zone, with a mean annual precipitation (MAP) of ~780 mm, 70% of which falls as snow.

Number of replicates was recorded for each date × aspect × plot combination.
