Chapter I: ENDNOTES 1 Dr. John W. Scott, letter, 1946. 2 37.5 on summit of Mount Lemmon, in Arizona (Schwalen, 1942, p. 442 and map). 3 Martin and Mattice, 1930, p. 12 6 Many ecologists separate the scrub oak belt from the piñon-juniper area, which more commonly denotes the Upper Sonoran zone. Such a subdivision is entirety justifiable for local studies, but the climatic differences are relatively minor, and a large number of animal life zone indicators are common to both, so that for broad descriptive treatments of climate in such large areas as the Colorado River Basin, the old system of combining them into one zone is retained here for simplicity's sake. 9 Precipitation does not increase with altitude at a regular rate in all regions. In southeastern Utah, for example, to take some extreme cases, it averages 1 inch for each 112 feet of rise between St. George and Andersons Ranch (near Leeds); 1 inch per 328 feet between Castle Dale and Hiawatha; 1 inch per 730 feet between Green River and Castle Dale; 1 inch per 403 feet between Green River and Watson; and 1 inch per 515 feet between Duchesne and Fruitland.
