Geologic Map of the Long Valley Caldera, Mono-Inyo Craters
DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP 1-1933 US. GEOLOGICAL SURVEY GEOLOGIC MAP OF LONG VALLEY CALDERA, MONO-INYO CRATERS VOLCANIC CHAIN, AND VICINITY, EASTERN CALIFORNIA By Roy A. Bailey GEOLOGIC SETTING VOLCANISM Long Valley caldera and the Mono-Inyo Craters Long Valley caldera volcanic chain compose a late Tertiary to Quaternary Volcanism in the Long Valley area (Bailey and others, volcanic complex on the west edge of the Basin and 1976; Bailey, 1982b) began about 3.6 Ma with Range Province at the base of the Sierra Nevada frontal widespread eruption of trachybasaltic-trachyandesitic fault escarpment. The caldera, an east-west-elongate, lavas on a moderately well dissected upland surface oval depression 17 by 32 km, is located just northwest (Huber, 1981).Erosional remnants of these mafic lavas of the northern end of the Owens Valley rift and forms are scattered over a 4,000-km2 area extending from the a reentrant or offset in the Sierran escarpment, Adobe Hills (5-10 km notheast of the map area), commonly referred to as the "Mammoth embayment.'? around the periphery of Long Valley caldera, and The Mono-Inyo Craters volcanic chain forms a north- southwestward into the High Sierra.

Snow Hydrology with Dr
Snow Hydrology with Dr. Ned Bair Ologies Podcast January 14, 2019 Oh hey, it’s that blueberry bagel that tastes like onions ‘cause it pressed its face into an everything bagel. Alie Ward, back with another episode of Ologies. It’s the middle of January, and here in the northern hemisphere, lips are chapped, feet are cold, parkas are on. I’m here to give you a snow job. But first, thank you to everyone who supports on Patreon, and who gets merch, including the new black t-shirts (yes!) at OlogiesMerch.com. Of course, thanks to everyone who rates and subscribes, who leaves reviews on iTunes, you know I read them. You know I read them. For example, this week, thank you to Evie, who said, In the hopes of Alie noticing me [heeyyy], I gotta say that this podcast just recently got me through some pretty bad flying anxiety. So thank you. Thank you for taking me into the sky with you, Evie. Also, EvanDK, I hope you and your pops are feeling okay. Okay, so: snow. Snow! Not just snow, but big cold crumbly scary dangerous avalanches. What the hell are they? I searched far and wide for a snow expert, and I connected with a dude who got his Ph.D. in Environmental Science and Management from University of California, Santa Barbara, a place Steven Ray Morris and I both attended, but this guy is primarily based up near Mammoth Mountain, which is technically a giant lava dome complex. Freakin’ volcano, near Yosemite. It’s chill. -
The History of Valentine Camp by Mary Farrell
History of Valentine Camp Mary M. Farrell Trans-Sierran Archaeological Research P.O. Box 840 Lone Pine, CA 93545 November 7, 2015 Prepared for Valentine Eastern Sierra Reserve University of California, Santa Barbara, Natural Reserve System Sierra Nevada Aquatic Research Laboratory 1016 Mt. Morrison Road Mammoth Lakes, CA 93546 Abstract Located in Mammoth Lakes, California, Valentine Camp and the nearby Sierra Nevada Aquatic Research Laboratory form the Valentine Eastern Sierra Reserve, a field research station in the University of California's Natural Reserve System. The University’s tenure at Valentine Camp began over 40 years ago, but the area’s history goes back thousands of years. Before the arrival of Euroamericans in the nineteenth century, the region was home to Paiutes and other Native American tribes. Land just east of Valentine Camp was surveyed under contract with the United States government in 1856, and mineral deposits in the mountains just west of Valentine Camp brought hundreds of miners to the vicinity in the last decades of the nineteenth century. Even as mining in the region waned, grazing increased. The land that became Valentine Camp was patented in 1897 by Thomas Williams, a rancher and capitalist who lived in Owens Valley. It was Williams’s son, also Thomas, who sold the 160 acres to Valentine Camp’s founders. Those founders were very wealthy, very influential men in southern California who could have, and did, vacation wherever they wanted. Anyone familiar with the natural beauty of Mammoth Lakes would not be surprised that they chose to spend time at Valentine Camp. Valentine Camp was donated to the University of California Natural Land and Water Reserve System (now the Natural Reserve System) in 1972 to ensure the land’s continued protection. -

Chapter 8 Manzanar
CHAPTER 8 MANZANAR Introduction The Manzanar Relocation Center, initially referred to as the “Owens Valley Reception Center”, was located at about 36oo44' N latitude and 118 09'W longitude, and at about 3,900 feet elevation in east-central California’s Inyo County (Figure 8.1). Independence lay about six miles north and Lone Pine approximately ten miles south along U.S. highway 395. Los Angeles is about 225 miles to the south and Las Vegas approximately 230 miles to the southeast. The relocation center was named after Manzanar, a turn-of-the-century fruit town at the site that disappeared after the City of Los Angeles purchased its land and water. The Los Angeles Aqueduct lies about a mile to the east. The Works Progress Administration (1939, p. 517-518), on the eve of World War II, described this area as: This section of US 395 penetrates a land of contrasts–cool crests and burning lowlands, fertile agricultural regions and untamed deserts. It is a land where Indians made a last stand against the invading white man, where bandits sought refuge from early vigilante retribution; a land of fortunes–past and present–in gold, silver, tungsten, marble, soda, and borax; and a land esteemed by sportsmen because of scores of lakes and streams abounding with trout and forests alive with game. The highway follows the irregular base of the towering Sierra Nevada, past the highest peak in any of the States–Mount Whitney–at the western approach to Death Valley, the Nation’s lowest, and hottest, area. The following pages address: 1) the physical and human setting in which Manzanar was located; 2) why east central California was selected for a relocation center; 3) the structural layout of Manzanar; 4) the origins of Manzanar’s evacuees; 5) how Manzanar’s evacuees interacted with the physical and human environments of east central California; 6) relocation patterns of Manzanar’s evacuees; 7) the fate of Manzanar after closing; and 8) the impact of Manzanar on east central California some 60 years after closing. -
