F. Richardson 1937 Month of 20-mile Creek, 9 mi S Add, Lake Co., Oregon May 25, 1937 - A brief description of the immediate region were appropriate now - today being our first day of collecting and intensive investigation of this country! - The main Warner Valley, into which 20-mile Creek opens, is extensive, quite flat, with larger growth as small willows typically only where canyons enter the valley. The amount of rain has apparently been exceptionally large this year resulting in large expanses of shallow water with tules, grasses etc. This has provided a habitat for various water birds. (Only cursory observed. Snailers, Cinnamon Teal, Gulls, Mallards - seen paired for example.) 20-mile Creek runs about east and west; volcanic ridges go up fairly steeply from the stream on either side of the canyon, becoming fairly high even at the mouth of the canyon. (From 300-500 ft.) The canyon is fairly flat towards its mouth, widening during its last half-mile or so, to about 1/4 mile! This has apparently made possible a more extensive riparian habitat at this part with more willow thicket and open meadow. Briefly, the chief habitats so far encountered have been - riparian, willow and cottonwoods; meadow, marshy, low meade or cultivated field; high chaparral, on level near stream, grading into riparian; low chaparral, on hillside, rather sparse
