Site ID: CARSNOW
Description: This is a weather station and NRCS Snow course location in the Caribou Poker Creeks Research Watershed.
Directions: NA
Site History: NA
Location: NA
Site ID: CPCRW_NADP
Description: This site is where the National Atospheric Deposition Program bucket is located in the CPCRW watershed region.
Directions: NADP sampler is located about 200m north of the confluence of Caribou and Poker Creeks in CPCRW.

Location: NA
Site ID: CPEAK
Description: This is a weather station on the summit of Caribou Peak (2537' / 773m ASL) in the Caribou Poker Creeks Research Watershed. It consists of a 10-meter tower with various atmospheric sensors and ground temperature thermistors at eleven different depths.
Directions: The Caribou Poker Creeks Research Watershed is located off the Steese Highway 31 miles northeast of Fairbanks. The first two miles of Watershed Road (restricted access) can be driven with a car or truck to the confluence of Caribou and Poker creeks. From there, access to Caribou Peak via the Caribou Trail usually requires an ATV (or a snowmachine in the winter season). Turn right at the T-junction just above the confluence area and follow the trail straight up Caribou Peak (approximately 2 miles). On the summit of Caribou Peak there are two weather stations. The station to the west is a RAWS site that belongs to the Alaska Fire Service (BLM). The station to the east is the LTER CPEAK site.
Site History: The current met tower was installed in April 1998. This replaced an earlier station that was in service from 1993 through 1997. The station logged data during the FROSTFIRE experimental burn that took place in July 1999. In 2001 the station was connected to a radio telemetry network, allowing for remote data acquisition and near-real-time data displays on the Internet.
Location: The site is located on the broad summit area of Caribou Peak, right at the treeline elevation. There are no higher peaks nearby to limit the exposure of this site.
Site ID: CRREL-Met
Description: This is considered the primary climate station in the Caribou Poker Creeks Research Watershed. Located in the lower part of the watershed near the confluence of Caribou and Poker creeks, this station consists of a 12-meter tower with various atmospheric sensors, a separate tower with long and short wave radiometers, ground temperature sensors and soil moisture probes at various depths, plus an older site about 25 meters away with two air temperature sensors and additional ground temperature thermistors.
Directions: The Caribou Poker Creeks Research Watershed is located off the Steese Highway 31 miles northeast of Fairbanks. The first two miles of Watershed Road (restricted access) can be driven with a car or truck during the summer months. After driving across the bridge over Poker Creek, the CRREL tower will be seen about 100 meters ahead and to the left of the road. A short footpath leads from the road to the site. The radiometer tower is to the left (south) of the 12m tower and the CRREL AT sensors and datalogger are about 25m behind (west of) the tower.
Site History: The station's name comes from the agency that originally managed CPCRW and set up many of the research sites, the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL). The original site consisted of the CRREL AT air and ground temperature instruments, the radiometer tower, and a 3m tripod with air temperature, relative humidity, and wind sensors. In May 2000, the Water and Environmental Research Center (UAF) replaced the 3m tripod with the current 12m tower. New instruments for temperature, RH and wind were installed at this time. A tipping bucket rain gauge was added (plugged into the CRREL AT datalogger) in June 2003.
Location: Valley location, wind-sheltered, cold spot in winter. It is on a slight south-facing slope in open canopy black spruce, feather moss, and sphagnum moss; less than 100m from Caribou Creek.
Site ID: HR1A
Description: This is a meteorological site near the crest of Helmer's Ridge, just west of the C4 basin, and at an elevation of approximately 610 meters
Directions: Traveling north from the confluence of Poker and Caribou Creeks, take a left at the T junction. From this point, the trail is only suitable for off-road vehicles. Immediately past the C4 bridge, the Helmer's Ridge trail branches off to the right. Follow this trail for about 3km to the site. Site is on north side of trail.
Site History: Precipitation data has been collected at this site since 1983. A sensor for air temperature was added in March 1992. The site was upgraded in June 2001 with the addition of a tipping bucket rain gage. Various problems with the instrumentation have led to some large gaps in the data record. The site must be visited periodically to download the data from a Campbell datalogger. In 2013, this site was added to the Regional Site Network (RSN) with the age class designation of "Young".
