These notes are explanations of what may appear to the reader to be inconsistencies of style, spelling and cartography. I hope that I have caught them all. Numbers of four digits or more in the text and tables have a comma between the third and fourth digit; they do not in the illustrations and plates. This is because some of the more complex illustrations and plates that have many numbers were produced from existing negatives from other publications that used a different style. We promised not to alter any negatives we borrowed, so sacrificed consistency to economy.
Names of mammals used in the text and appendix are after the 1973 Checklist of North American Mammals North of Mexico (Jones, Carter and Genoway, 1973). Bird names and spellings, common and scientific, are after The Auk ( 1973; Parkes, 1978). Common and scientific names of reptiles and amphibians are after The Vertebrates of Arizona (Lowe, 1972). Plant common names vary greatly. Scientific names for those plants, listed in Appendix B, are after A Catalogue of the Flora of Arizona (Lehr, 1978).
Readers may note that a species of sage is identified as being Mojave sage while a species of yucca is known as Mohave yucca. Perhaps an entry in the 1935 edition of Arizona Place Names, by Will C. Barnes, explains this apparent inconsistency.
An Act of the 13th Legislative Assembly of Arizona contained a clause to the effect that: ‘‘The county seat of Mohave county shall be at Mineral Park or some place located on the Atlantic and Pacific (R)ailway within said county.’’
The Howell code originally spelled this word Mojave, but according to authorities of that day, ‘‘due to an ignorant clerk,’’ the legislative act above quoted spelled it Mohave. Word now seems to be uniformly spelled Mohave, excepting the post office in California which has always used the ‘‘j.’’
Authorities differ on it. Hodge says Navajo, while others write it Navaho. Broadly speaking, scientists and ethnologists have decided on the spelling(s) Navaho and Mohave as most satisfactory and (they are) gradually coming into use. As long as Congress uses a certain form, that is legal for the particular place or thing.
La Paz County does not appear on the Arizona General Soil Map (Plate 1) in accordance with an agreement between the author, editor and the state soil scientist, whose permission was necessary for us to reproduce the map using colors that are keyed to the colors selected for the other color plates. The original map was published in 1975. All other state maps show La Paz County, which became operational January 1, 1983 following a vote by Yuma County citizens on September 7, 1982. The tilde (~) is not used in spelling proper names in Spanish, again, because none was used in the text of the original soils map.
Twenty-four images transmitted to Earth by Landsat between August 24, 1972 and October 12, 1973 were used to make the Arizona Satellite Image Map, 1972- 1973 shown here. Landsat orbits at an altitude of about 920 kilometers (570 miles). The map was published by the U.S. Geological Survey in cooperation with NASA.
