The species included in this list were collected from Lost Lake (L) and East Glacier Lake (EG) and West Glacier Lake (WGL) and identified by Richard Dufford, Phychologist, in 1988. The collection is maintained by Mr. Dufford in Fort Collins, Colorado. Samples were collected as an integrated sample from a water column at the deepest section of the lake.
This Appendix identifies macroinvertebrate species found in streams and lakes at GLEES during a preliminary qualitative survey conducted in the summer of 1988 by Dr. Boris Kondratieff. The littoral zones of each lake and each stream were sampled by hand-picking and with a triangle net. Insect voucher specimens are maintained in the Gillette Entomological Museum at Colorado State University in Fort Collins, CO.
The soils map of GLEES watersheds is shown in chap. 5, fig. 5.1 and the map units are described in this Appendix.
A soil survey was conducted of the East Glacier, West Glacier and Lost Lake watersheds in July-September 1986. Procedures appropriate for an Order 3 soil survey were followed. Fifteen locations were surveyed and a total of 166 samples were analyzed. The 15 series are listed below, along with the soil classification and number of samples analyzed.
Within the GLEES boundary there are three alpine lakes and several streams and ponds. The selection of GLEES as a research site for investigating of the effects of chemical and physical climate change was in part based on the accessibility of these low alkalinity "sensitive" aquatic ecosystems. This chapter provides a brief description of the physical, chemical, and biological characteristics of the GLEES aquatic ecosystems.
The initial habitat classification as described in Chapter 2 was conducted in 1986 and 1987 based upon field identification of plant species. A field collection of vascular plant species was made during the 1988, 1989, and 1990 summer seasons. The plant species collected were identified and verified in cooperation with the Rocky Mountain Herbarium at the University of Wyoming. Voucher specimens are archived at the Herbarium.
The Medicine Bow Mountains have a core of Precambrian rocks. They contain the boundary, the Cheyenne Belt, between the Wyoming Province to the NW and the accreted Proterozoic continental crust to the SE (Karlstrom and Houston 1984). The Wyoming Province consists of Archean rocks that are locally intruded and (or) overlain by rocks of Proterozoic age, including the lithologies present in the West Glacier Lake drainage basin.
Tenderfoot Creek Experimental Forest (TCEF) is located in Central Montana 24 miles north of White Sulphur Springs and 9 miles northwest of Highway 89 from Kings Hill via Forest Road #839. The experimental forest can also be accessed by Forest Road #586 via Sheep Creek. A general view of TCEF showing roads and drainages is shown in figure 2. The road down Tenderfoot Creek is open only to Administration Travel vehicles.
Three Parshall flumes were installed within East and West Glacier Lakes watersheds during the summer of 1987. Each Parshall flume was prefabricated fiberglass construction fitted with a hypolon liner to bring as much groundwater flow as possible to the surface so that it could be measured by passing the water through the flume.
Wilderness ecosystems in the United States are federally mandated and set aside by the Wilderness Act. They are managed to minimize human impact using methods that leave these systems, to the extent possible, in their natural state uninfluenced by manipulation or disruption by humans.
