| General Description |
The tributary basins of Caribou Creek are all arbitrarily designated with a "C". The C2 basin is the sub-basin with the least amount of permafrost of the CPCRW sub-basins. As such, it has been often been studied intensively in conjunction with C3, the sub-basin with the greatest amount of permafrost. The basin trends to the south, with well-drained slopes and permafrost-underlain treeless muskeg in valley bottom. Although an extensive fire history has not been done, there was probably a stand-replacing fire early in this century (ca. 1925), with some large white spruce stands that survived from the earlier vegetation.
|
| Vegetation Description |
The closed canopy mature white spruce vegetation type is found as "stringers" in the steep, south-facing, headwater slopes that are associated with topographic depression and hence are quite wet. These 150-200 year old trees are probable survivors of the regional wildfires associated with mining activity since the turn of the century. The closed canopy birch and aspen stands are found on the south- and west facing slopes, while the open canopy black spruce is found on the east-facing slopes. The valley bottom contains treeless closed low birch and willow shrub (muskeg).
|
| History |
The flume at C2 was first installed in about 1974.
|
| Directions |
The C2 basin is accessible by all-terrain vehicle or snow machine by a trail that runs west from the confluence of Caribou and Poker Creeks. Stay to the right at the "T" junction about 3 miles up the valley: the left turn goes to the CB and C3 sites, and up the trail to Haystack Mountain. The passable (by vehicle) portion of the C2 trail ends at the flume in the C2 valley bottom, and an unmaintained, walkable trail goes up into the headwaters of the main C2 tributary.
