Located approximately 1 mile east of east corner of Big Lake on first 
ridge top. Elevation 200 feet, site level. Dry lichen-willow-Dryas- 
sedge tundra. Much exposed soil and pebble layer from wind erosion. 
Lichen layer very thin, less than % inch and badly shattered. Some de- 
tached dry mosses also mixed with lichens. Lichens mostly Cetraria 
cuculata, Thamnolia vermicularis and some Cladonia alpestris. This is 
a windswept area which has received heavy winter utilization by reindeer. 
Wind erosion has been active. | 
The north and south plots, I and III, are protected from reindeer 
grazing by fencing. The east and west plots, II and IV, are unprotected. 
The fence enclosure is 9 by 15 feet. The site photograph of the enclo- 
sure was taken 50 feet west of the enclosure from a permanent photo-
