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. Although these trending zone of volcanic vents extending 45 km from lavas never formed a continuous cover over this region, the west moat of the caldera to Mono Lake. The their wide distribution suggests an extensive mantle prevolcanic basement in the area is mainly Mesozoic source for these initial mafic eruptions. Between 3.0 granitic rock of the Sierra Nevada batholith and and 2.5 Ma quartz-latite domes and flows erupted near Paleozoic metasedimentary and Mesozoic metavolcanic the north and northwest rims of the present caldera, at rocks of the Mount Morrisen, Gull Lake, and Ritter and near Bald Mountain and on San Joaquin Ridge Range roof pendants (map A). -

Insights Into Rhyolite Magma Dome Systems Based on Mineral and Whole Rock Compositions at the Mono Craters, Eastern California
ABSTRACT INSIGHTS INTO RHYOLITE MAGMA DOME SYSTEMS BASED ON MINERAL AND WHOLE ROCK COMPOSITIONS AT THE MONO CRATERS, EASTERN CALIFORNIA The Mono Craters magmatic system, found in a transtensional tectonic setting, consists of small magmatic bodies, dikes, and sills. New sampling of the Mono Craters reveals a wider range of magmatic compositions and a more complex storage and delivery system than heretofore recognized. Space compositional patterns, as well as crystallization temperatures and pressures taken from olivine-, feldspar-, orthopyroxene-, and clinopyroxene-liquid equilibria, are used to create a new model for the Mono Craters magmatic system. Felsic magmas erupted throughout the entire Mono Craters chain, whereas intermediate batches only erupted at Domes 10-12 and 14. Mafic magmas are spatially restricted, having erupted only at Domes 10, 12 and 14. Data from the new whole rock analyses illustrates a linear trend. Fractional crystallization does not replicate this trend but rather the linear trend indicates magma mixing. This study also analyzes samples from the Mono Lake Islands and the June Lake Basalts and compares them to the Mono Craters. Although the Mono Lake Islands fall into the intermediate to felsic group, they contain distinctly higher Al2O3 and Na2O at a given SiO2. Therefore, this study concludes that the Mono Craters represent a distinct magmatic system not directly related to the magmatic activity that created the Mono Lake Islands.

Chapter 3K. Environmental Setting, Impacts, and Mitigation Measures - Cultural Resources
Chapter 3K. Environmental Setting, Impacts, and Mitigation Measures - Cultural Resources This chapter addresses potential impacts of the alternatives on cultural resources in Mono Basin and Upper Owens River basin. Impacts are generally in the realm of potential disturbance to cultural resource sites from channel erosion, recreational activity, and restoration activities along the diverted streams and Owens River. Few effects would result from establishing higher or lower lake levels because no sites are expected to be present on the relicted lands. As described below, some diminishment in the use of the lake's food resources by Native Americans may have occurred during the diversion period, but choice of an alternative would little affect future resource utilization as long as resources of Native American importance are avoided during restoration activities. SOURCES OF INFORMATION Background Research A record search was conducted at the Eastern Information Center of the California Archaeological Inventory, University of California, Riverside, to determine the types and locations of known cultural resources within the areas of concern. Primary and secondary archeological, ethnographic, and historical sources were consulted for information pertaining to the areas of concern, including: # the National Register of Historic Places, # California Historical Landmarks, and # California Inventory of Historical Resources. Literature considered in this process is cited in the following discussions. Information on the Mono Lake Paiute is presented by Davis (1959, 1961, 1965, 1962, 1963, 1964), Curtis (1926), Kroeber (1925), and Merriam (1955, 1966:Part 1). Primary accounts of the Owens Valley Paiute are contained in Steward (1929, 1933, 1934, 1936, 1938a, 1938b). Additional information can be found in Davis (1961), Driver (1937), Kroeber (1925, 1939, 1959), and Merriam (1955). -

Marks: Sheep Replace Pronghorn Sheep Replace Pronghorn: An Environmental History of the Mono Basin Robert B. Marks1 Environmental history examines the relationships of humans to the natural environment. It is concerned with understanding the environmental circumstances that condition the ways in which humans are able to obtain their subsistence, and the extent to which the ways they do so changes the environment. Sometimes humans have a very light, and ultimately sustainable, touch on the environment, and sometimes their environmental impact is heavy and not sustainable, threating the environmental underpinnings of human societies. To gauge the history of human impact on the environment, a major task is reconstructing past environments. Written sources are useful, but when they are missing or silent, archeological and paleobotanical findings can be used. -

Exploring the Southern Sierras: Water, Snow & Ecosystem
Exploring the Southern Sierras: Water, snow & ecosystem monitoring across the range The Sierra Nevada marks the geographic boundary between the great Central Valley of California to the west and the Basin and Range province to the east. The range comprises diverse ecosystems: traveling from west to east, you encounter rolling oak woodlands, dense montane coniferous forests, alpine meadows and peaks, and back down to Pinyon pine-Juniper forests and scrublands on the eastern face of the range. In this semi-arid climate, snowpack accumulation in the mountain range constitutes a critical resource for the larger region. Runoff from the Sierras is used by more than 10% of the population of the United States. Sierra Nevada runoff also sustains agriculture in the Central Valley of California, a multi-billion dollar industry providing a considerable portion of the country's produce. Research on hydrology, climate, and ecosystem interactions in this region has immense implications for regional livelihoods and policies. To study these topics in the Sierra Nevada, there are several long-term monitoring sites scattered across the region. This trip will give you a first-hand look at many of the sites, including the SNOTEL installation at Virginia Lakes Ridge, the GLORIA monitoring site, long- term collaborative monitoring of the Mono Basin , the Southern Sierra Critical Zone Observatory, and monitoring efforts by the National Park Service Inventory & Monitoring Program at Yosemite National Park. The trip will take approximately 3 days and include travel to elevations as high as 10,000’/3048 m (as well as an optional hike to near 11,000’/3353 m). -
