Mojave Desert Trails explores some of the most interesting historic and geological sites in the Mojave Desert. Ecologically and environmentally diverse, the Mojave Desert encompasses a dramatic and enchanting landscape of ancient volcanic cinder cones, Joshua tree forests, sand dunes and rugged mountains. Weather in the Mojave changes as dramatically as its terrain: triple digits from late spring to early fall with winter temps often dropping below freezing. A wet winter, with both rain and snow, will prepare the Mojave Desert for a spectacular display of spring flowers.

Not illustrated. 1902 Excerpt: ...earth. r' = radius of moon, or other body. P = moon's horizontal parallax = earth's angular semidiameter as seen from the moon. f = moon's angular semidiameter. Now = P (in circular measure), r'-r = r (in circular measure);.'. r: r':: P: P', or (radius of earth): (radios of moon):: (moon's parallax): (moon's semidiameter). Examples. 1. Taking the moon's horizontal parallax as 57', and its angular diameter as 32', find its radius in miles, assuming the earth's radius to be 4000 miles. Here moon's semidiameter = 16';.-. 4000::: 57': 16';.-. r = 400 16 = 1123 miles. 2. The sun's horizontal parallax being 8"8, and his angular diameter 32V find his diameter in miles. ' Am. 872,727 miles. 3. The synodic period of Venus being 584 days, find the angle gained in each minute of time on the earth round the sun as centre. Am. l"-54 per minute. 4. Find the angular velocity with which Venus crosses the sun's disc, assuming the distances of Venus and the earth from the sun are as 7 to 10, as given by Bode's Law. Since (fig. 50) S V: VA:: 7: 3. But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated ...

First published in 1930, Salt Desert Trails tells the story of the Great Salt Desert crossings by early explorers and emigrant parties. Central to the story is the opening of the Hastings Cutoff in 1846, which led to the tragedy of the Donner Party and the pioneering of the emigrant trails through Utah’s Wasatch Mountains.

Backpacking California is a collection of more than 70 of the most intriguing backpacking adventures in Wilderness Press's home territory of California. With contributions from more than a dozen Wilderness Press authors, the book describes routes ranging from one night to one week. Backpacking novices as well as "old hand" California hikers will find expert-crafted trips in the Coast Ranges, the Sierra, the Cascades, and the Warner Mountains. Expanded coverage includes trips in Big Sur, Anza-Borrego, Death Valley, and the White Mountains. Several trips have been described in print nowhere else. Each trip includes a trail map and essential logistical information for trip planning.

The cult-y pocket-size field guide to the strange and intriguing secrets of the Mojave—its myths and legends, outcasts and oddballs, flora, fauna, and UFOs—becomes the definitive, oracular book of the desert For the past five years, Desert Oracle has existed as a quasi-mythical, quarterly periodical available to the very determined only by subscription or at the odd desert-town gas station or the occasional hipster boutique, its canary-yellow-covered, forty-four-page issues handed from one curious desert zealot to the next, word spreading faster than the printers could keep up with. It became a radio show, a podcast, a live performance. Now, for the first time—and including both classic and new, never-before-seen revelations—Desert Oracle has been bound between two hard covers and is available to you. Straight out of Joshua Tree, California, Desert Oracle is “The Voice of the Desert”: a field guide to the strange tales, singing sand dunes, sagebrush trails, artists and aliens, authors and oddballs, ghost towns and modern legends, musicians and mystics, scorpions and saguaros, out there in the sand. Desert Oracle is your companion at a roadside diner, around a campfire, in your tent or cabin (or high-rise apartment or suburban living room) as the wind and the coyotes howl outside at night. From journal entries of long-deceased adventurers to stray railroad ad copy, and musings on everything from desert flora, rumored cryptid sightings, and other paranormal phenomena, Ken Layne's Desert Oracle collects the weird and the wonderful of the American Southwest into a single, essential volume.

The definitive guide to more than 300 of the most remote and diverse desert mountains in Anza-Borrego, Death Valley, Red Rock, Spring Mountains, Toiyabe Forest, and more! Complete with tips, directions, descriptions, 18 maps, and over 130 photos.
