CZNet DWCZ - CO - Gordon Gulch 1 & 2, SWE along Snow Pole Transects (GG1-GG2-SWE) -- Gordon Gulch -- (2023)

Description/Abstract

MAR-01-2023 to ongoing - seasonal SWE measured by calibrated scale including mass of tube (cm)

For North aspects, downslope is between the lowest snow pole and second-lowest snow pole. Upslope is between the highest snow pole and second-highest snow pole. For South aspects, data were collected between the two snow poles and this entry is left blank.

LOCATION : Gordon Gulch (GG1) & (GG2) LOCATION DESCRIPTION: Gordon Gulch (2590 m) lies within Arapahoe National Forest and is divided into 1 (lower) and 2 (upper) Gordon Gulch. 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.

For North aspects, downslope is between the lowest snow pole and second-lowest snow pole. Upslope is between the highest snow pole and second-highest snow pole. For South aspects, data were collected between the two snow poles and this entry is left blank. Number of replicate done at each date aspect plot combinationnamic eatter
