LOGGING CREEK
Cheyenne Reservation
Site # MY - 18
To reach this site, turn south from U.S. 212 onto the Tongue River Road, about one mile west of Ashland (0.1 mile east of mile #61). Drive 2.3 miles and turn west onto the Logging Creek road, #203. 5.4 miles up the road is the first cattle guard. The site is on the meander to the south of the cattle guard.
This site is at a broad bend in the creek. Cross-section 2 is at a sharp meander, and cross-sections 1 and 3 are across relatively straight reaches up and down stream.
The stream has cut a vertical 3 meter high cliff on the right bank between cross-sections 1 and 2, and for about 20 meters up and down stream from 1 and 2, respectively. This cut exposes mostly silt, with some gravel lenses. The gravel is up to about 5 centimeters in diameter.
Land use is grazing. The pasture is dry, but not overgrazed. The stream banks are not excessively knocked down by cattle. The banks are well covered with vegetation, except for the high vertical bank.
The stream water is very clear, and flowing moderately fast. The water is also cold. Apparently some of the flow is derived from nearby springs. The stream bottom in the pools is entirely covered with aquatic vegetation.
Logging Creek has a well developed pool-riffle system. There are two riffles within the reach mapped. The pools are covered with silt and clay, and the riffles are composed mainly of sedimentary rock and clinker clasts.
Logging Creek (Site # MY - 18) was surveyed 30 August 1975.
Angles determined by a Brunton are followed by a (B), all others derived from plane table data. Distances determined with a tape are followed by a (T), all others found using the alidade. The rod is touching the alidade side of the survey point, and is centered. Compass compensation is 15.5°. See Table 1.
